Detailed description

In the following description sets forth numerous details to facilitate understanding of the present invention. However, specialists in the art should understand that the present invention can be used without these details and that there are many possible variations or modifications relative to the described embodiments.

The present invention relates to a system and method for Burov the x operations and operations with pump-compressor pipe with one rig. The combined rig for drilling and the use of flexible tubing is designed to eliminate the use of top drive or power swivel system, thereby reducing the requirements for hydraulics, risk factors and cost factors the usual sites for drilling through flexible tubing. Basically, the system and method use a tower having a base with a support attached to the base. Drum flexible tubing is also installed with the ability to rotate on the base with the spindle, and the injector flexible tubing is installed on the mast to facilitate operations with flexible tubing pipe. Additionally, moving the tip of the actuator is installed on the mast to facilitate connection and disconnection of the components of the column of tools, such as components downhole node or other components of the column of tools. The tip of the starter is not involved in the drilling, but uses a smaller engine, such as an electric motor or hydraulic motor, the size is sufficient for the transmission of rotational motion components of the columns of the instruments sufficient for the connection and disconnection of the components of the column of tools. Energy for drilling is provided downhole drilling motor that about is launched into the hole with drill string. The tip of the starter usually does not rotate during drilling and may be used to counter the torque generated during the drilling operation.

Figure 1 illustrates a variant implementation of the present invention. In this embodiment, flexible tubing and rig 20 contain the base 22. As an example, the base 22 may be made in the form of trailer 24, such as a cargo trailer that is supported by many of the wheels 26. In this embodiment, the base 22 is intended for coupling with motorized transport 28, such as a tractor, to create a tractor-trailer vehicle, which can move from one drilling site to another. There are many ways of implementing the trailer 24 and motorized transport 28 is designed to move on the roads, allowing you to transport tubing pipe and drilling equipment on the public high-speed highways. It should be noted, however, that the base 22 may be constructed in other forms, including self-propelled forms that do not depend on a separate tractor, to move rigs for drilling and application of pump-compressor pipes. The base 22 may also contain stabilizing equipment such as a set of supports 30 article is bilization, which can be selectively abut the surface of the earth to align and stabilize the base 22 during drilling operations and operations with pump-compressor pipe.

Tower 20 for drilling and use of tubing further comprises a mast 32, mounted on the base 22. In the illustrated embodiment, the mast 32 is mounted to the structure 34 having a platform 36 on which is mounted structure 38 for supporting the component, such as a rotary table. Structure 38 for supporting the component is intended for connection of the components of the column of tools, such as pipe, using the appropriate connecting mechanism (not shown), for example, wedge grips, as is well known to specialists in this field of technology. All the mast 32 may be movably mounted on the movable element 40 to provide descent of the mast in the storage position for transport to another drilling site. The hydraulic cylinder 42 can be used to move the mast 32 between a storage position and an upper working position, as illustrated in figure 1.

The injector 44 of flexible tubing mounted on the mast 32 by means of a mounting structure 46. Mounting structure 46 may be designed to provide a platform 48 on which the injector 44 flexible pump is impressoras pipe is mounted movably through the feeding mechanism 50. Feeding mechanism 50 can be used to move the injector 44 flexible tubing into and out of aligned position with the mast 32, for example, depending on the type of drilling operations or operations with flexible tubing pipe. The injector 44 flexible tubing may also contain a lubricating device 52 that is designed for guiding the flexible tubing 54 of the injector 44 flexible tubing when the flexible tubing is placed in the bore 56. Arch 58 of the injector may be connected to or located on the upper side of the injector 44 flexible tubing. Arch injector 58 is an arched structure, which facilitates the bending of the flexible tubing 54 and moving the flexible tubing 54 into the injector 44.

Flexible tubing and rig 20 may further comprise a drum 60 for flexible tubing mounted on the base 22. As illustrated, the flexible tubing 54 is wound on the drum 60 is delivered to the injector 44 flexible tubing. During operations with flexible tubing pipe, the drum 60 is selectively rotates around the spindle 61 to deliver flexible pump comp is asarnoj pipe 54 into the bore 56, or to retrieve the flexible tubing from the well. The drum 60 can be rotated using a conventional motor for drum flexible tubing. In one embodiment, the energy for the rotation of the drum 60 of flexible tubing, for pull-out and retraction of the cylinder 42 and to perform various other requires energy operations on the rig 20 can be fed hydraulically by hydraulic source 62 and the source 64 of energy to compress the hydraulic fluid, for example an internal combustion engine and hydraulic pump.

The tip 66 of the actuator is also mounted on the mast 32 to move along the mast 32. For example, the tip 66 of the actuator can be raised and lowered along the mast 32 through the mechanism 68, which may have many forms depending on the particular application. For example, the mechanism 68 may include a release mechanism, the trigger mechanism is integrated in the mast, a winch or other suitable mechanisms for mechanical lifting and lowering of the tip 66 of the actuator. As will be explained in more detail below, the tip 66 of the actuator can be used in the Assembly of the components of the column of tools to support the load of the pipe to ensure a tight swivel device for pumping drilling fluid to provide lifts to the hydraulic actuator to move the comp is required columns of the tools and applications necessary efforts to the connections between the components of the column of tools, for example, components of the drill string. The tip 66 of the actuator can also be mounted on the device, such as a platform 48 and the feed mechanism 50, to provide movement of the tip 66 of the actuator above the well if necessary.

During operation with flexible tubing pipe, such as the descent downhole node in the hole 56, the injector 44 flexible tubing is moved into position relative to the main mast 32, as best shown in figure 2. The injector 44 flexible tubing is transported by the feeding mechanism 50, which translates the injector from the aligned position, as shown in figure 1, to a position aligned with the mast 32 and the bore 56. In this position, the injector 44 flexible tubing can be used to move the flexible tubing 54 in position for connection with components of the column of tools, such as downhole components of the site that fall into the well. In some applications, the flexible tubing may be used in drilling operations. In these applications, the injector flexible tubing combined with the area in which is formed a bore. When switching from operations with flexible tubing pipe to another operation, such as operas is tion drilling composite pipe, the injector 44 flexible tubing may be again moved by the feeding mechanism 52 in the off position. It should be noted that in some applications, the mounting structure 46 and the injector 44 flexible tubing can be used for movement along the mast 32.

Figure 3 tip 66 of the actuator shown in the lower position. The tip 66 of the actuator can be moved along the mast 32, if necessary, to perform various drilling operations and operations with flexible tubing pipe. For example, the tip 66 of the actuator can be used in the Assembly with composite pipes for drilling operations. However, the tip 66 of the actuator can be used to facilitate operations with flexible tubing pipe. For example, the tip 66 of the actuator can be used for clamping, lifting, positioning, connections and pivot connections between the components of the downhole node, which are sequentially connected to flexible tubing pipe 54 below the injector 44 flexible tubing.

Variant implementation of the tip 66 of the actuator illustrated in figure 4. In this embodiment, the tip 66 of the actuator is connected to the mechanism 68 transmission of motion by means of a suitable connecting structure. As shown, one option with dinusha structure 70 comprises a pair of separate pulleys. The tip 66 of the actuator can also include a connection 72 with the line of the drilling fluid, is connected to a rotating swivel 74, which can be used to maintain pressure during pumping material through the connection line 72 of the drilling fluid. Rotating swivel 74 may or may not rotate to maintain pressure during rotation depending on the specific application, which uses the tip 66 of the actuator. The lower part of the rotating swivel 74 contains a cartridge 76 is used to connect components of the column of tools. For example, the cartridge 76 can be used to connect components of the drilling downhole node.

A mechanical device 78 is used to rotate the Chuck 76, thereby allowing the formation or "twisting" of the connections between the components of the column of tools. A mechanical device 78 also allow for the proper application of rotation to an already established connection. As an example, a mechanical device 78 includes a gear 80 attached to the cartridge 76 and driven by a motor 82. The motor 82 may be an electric motor or hydraulic motor, which is relatively simple, with low power consumption, cheap compared to the standard engine, which is required for Verkhneportovaya. Much more energy is required for drilling, comes separate drilling motor 84, which falls into the hole 56 with the drill string 86. Thus, the downhole drilling motor 84 provides power for rotating the drill bit 88 is fully independent from the motor 82, which greatly increases the reliability, simplifies the design and reduces the cost of the tip 66 of the actuator.

The tip 66 of the actuator can also include a rod 90, such as a drill rod, which can be used to lock connectable or releasable components. Advanced hydraulic stop 92 may be used to prevent rotation of the components of the column of tools, such as the components of the downhole node during connection and disconnection. Resistant device can also be used to lock the cartridge 76 and prevent rotation of the holder 76 during drilling operations downhole motor 84. To further prevent rotation of the components of the tip of the starter during drilling operations protivovrashchatelnogo mechanism 93, such as one or more multi-faceted rods, can be located between the lug 66 of the actuator and the alignment structure, such as a mast 32, to prevent undesired rotation due to torque transmitted h is cut oil column 86 during drilling.

The tip 66 of the actuator can also include lifts 94, which can be used for holding components of the column. For example, the lifts 94 can be used to hold the components of the downhole node during the operations of Assembly and disassembly. Depending on the application, lifts 94 can be in the form of mechanized lifts. Mechanized lifts have the ability to open and close remotely. Lifts 94 can also include hydraulic cylinders 96, designed to control the position of the sling support lifts 94. This provides the lifts more opportunities for positioning for precise alignment of the components of the column of tools during installation and retrieval.

An example of using the tip 66 of the actuator and lifts 94 for connection of the components shown in figure 5 and 6. Initially, the tip 66 of the actuator is lowered to the bottom of the mast 32 to capture a video component 98 columns instruments, such as the downhole node, as shown in figure 5. The tip 66 of the starter then rises along the mast 32, allowing the lifts 94 to deviate by moving the component 98 under the action of gravity to align with the structure 38 of the support component, such as a rotary table. As soon as the tip 66 p is animedia enough to component 98 was suspended almost vertically above structure 38 of the support component, the component can be lowered into place by lowering the tip 66 of the actuator. For example, a component 98 may be omitted in the mouth 100 through the structure 38 to support component for connection with a further component. If the component 102 has already been suspended in the structure 38 for supporting the component, the tip 66 of the actuator is used to move a component 98 downward for engagement with the component 102, as shown by the arrow 104 figure 6. After gearing components 102 and 98 columns tool tip 66 of the actuator can be omitted to connect the cartridge 76 component 98. As discussed above, the motor 82 is then used to rotate the cartridge 76 and connecting components 98 and 102. Engine 82 can also be used for application of the desired force to the connection. Components and assemblies of components in the flexible tubing pipe and the drilling rig 20 allow the use of the rig in a wide variety of drilling operations and operations with flexible tubing pipe, comprising drilling operations with flexible tubing pipe. Additionally only the tip 66 of the actuator provides more functionality in supporting, connecting and disconnecting the downhole components, along the low risk high reliability and relatively low cost of the device. It should be noted, however, that the various components can be added to the tower 20, or may replace the illustrated components. Additionally, the tip 66 of the actuator can be used for a wide variety of applications, including the Assembly and disassembly of the downhole nodes, the Assembly and disassembly of the composite pipes, and many other applications. The injector 44 of the flexible tubing and the drum 60 of the flexible tubing can be used for many types of operations with flexible tubing pipe.
