The invention relates to oilfield equipment for sampling for analysis at the mouth of oil wells and can be used for integrated sampling multicomponent gas-liquid systems, transported through pipelines.

On the constructive and functional characteristics of the closest analogue is a sampling device (patent RU 2151290 G1), inside of which is the management body of the flow of multicomponent gas-liquid environment, equipped with sealing elements, select the camera in the form of sealed spherical segment with intake channels, the locking body with the guide tube, the valve of the sampling set with the ability to interact with a spring-loaded rod. The body of the flow control and shut-off body are driven individually by separate handles.

The disadvantages of the known devices include the complexity of the design, which increases its cost and operating costs, complicates maintenance. The control flow is driven through the shaft with Salnikov seal, want to strictly follow:

a) periodically re-tighten the packing to prevent leakage;

b) at least wear to add a lip seal or replace with a new set that is associated with the stop SK is Ainy, violation of ecology at the wellhead, etc.

There is a danger that distant from the main fluid flow details as the rod 38 (figure 4), the spring 39 may take the frost, as in the oil composition may be water, and the device will heat up during sampling. In addition, the device is mounted on a horizontally located the site of the discharge pipe, where multicomponent gas-liquid mixture has time to settle (settle) in a way that negatively affects the results of the sample analysis.

The technical problem solved by the invention are to simplify the design and maintenance of the device, improving the quality of sampling multicomponent gas-liquid environment.

The problem is solved in that the hollow body is a fragment of the discharge pipe at the vertical part of wellhead equipment, body control the flow of multicomponent gas-liquid medium is made in the form of the valve of smaller size than the inner diameter of the hollow casing, and the selected camera is a ring cavity in the hollow body, located at the valve and communicated to the inlet flow of multicomponent gas-liquid medium through the intake channels made symmetrically to the axis of rotation of the valve, a valve body and a stem fitted in the stupas under multiple threads of corresponding section, executed on the shaft for a length of not less than one-quarter of the axial step in this thread, and remote from the hollow body of the device is protected from the cold insulating material.

1 shows a frontal projection of the axial section of the device in operating position; figure 2 is a horizontal projection of the device in section; figure 3 - the damper shaft.

The device consists of a hollow body 1 (figure 1), representing a fragment of the discharge pipe at the vertical part of wellhead valves (not shown). Inside the hollow of the housing 1 is located a shaft 2 to which is attached (welded) flap 3, and the diameter of the valve is smaller than the internal diameter of the hollow body 1, thus formed annular gap 4 (2) for the passage of the mixed flow of multicomponent gas-liquid environment.

In the hollow body 1 is provided camera sample 5, is in communication with the annular gap 4 through the suction channels 6, performed at the level of the valve 3 and placed symmetrically to the axis of rotation of the valve 3. Inside the shaft 2 is a rod 7 with the opportunity to interact with the valve 8 sampling valve body with one hand, and on the other by the compression spring 9 mounted in the hollow bobince 10, protected from the cold insulating material 11, such as Styrofoam and the casing 12.

Valve sampling 8 represents the C itself bulb, mounted in the socket head 13 (2) of the drive screw 14 and fixed by way of compression. The cylindrical section of the head 13 is associated with the corresponding area of the body 15 of the locking device with the smallest gap that provides a delay sampling until complete closure of the valve 3 (figure 2). The saddle 16 is placed in the threaded boss 17 (figure 1) and recorded on a strip 18 with a coupling nut 19 through the housing 15 of the locking device with the discharge tube 20.

The rod 7 is equipped with a pin 21 projecting ends forming on the rod 7, the tabs under the appropriate desahogo thread as open dushani helical grooves 22 (Fig 3) length not less than one-quarter of the axial step of these grooves. L=0,25·t, where L is the necessary and sufficient length of the axial component of the helical grooves for opening and closing the valve, the t - axis step helical grooves.

The ends of pin 21 (Fig 1) on the periphery are located in the longitudinal grooves 23 of the hollow boss 10, which prevents cranking rod 7 in the process. Intermediate portions of the ends of the pin 21 in contact with the shaft by dushani helical grooves 22 (Fig 3).

For sampling of multi-component gas-liquid environment must be installed under the guide tube 20 cumulative capacity (not shown). On the back end 24 (1) of the drive screw 14 to put on the handle (not the azan), bundled with the device, turn it on turn until, until the cumulative capacity of the selected mixture. This occurs after at the same time the cylindrical section of the head 13 (2) of the drive screw 14 will be released from the coupling with the body 15 of the locking device and the valve 3 closes under the action of the projections of the shaft 7 to the shaft 2 through its helical grooves due to the potential energy of the spring 9, taken at its rasathi.

After selecting the required sample volume the drive screw 14 is turned to close the valve 8, to contact its seat 16, while at the same time the 8 ball valve selection pushes the rod 7 together with the projections 21 along the spiral grooves 22 (Fig 3) and opens the valve 3, turning it a quarter turn, thus favouring the passage of the produced well fluid through the hollow body 1 (Fig 1).

In operation, after using one side of the saddle 16 and the latter is set by the other party, indicating the rational use of metal saddle 16 (e.g., stainless steel) and, consequently, to improve the reliability of the device as a whole.

The elimination of the seals on the shaft body to control the flow of multicomponent gas-liquid environment can simplify the design of the device and its maintenance with simultaneous improving the AI quality sampling.

Sampling device for integrated sampling multicomponent gas-liquid medium containing installed in the pressure pipeline of the mouth of the hollow valve body, inside of which is the management body of the flow of multicomponent gas-liquid environment, select the camera with intake channels, a stop valve with a handle and guide tube, a drive valve sampling set with the ability to interact with a spring-loaded valve located inside of the shaft body to control the flow of multicomponent gas-liquid medium, characterized in that the hollow body is a fragment of the discharge pipe at the vertical part of wellhead equipment, body control the flow of multicomponent gas-liquid medium is made in the form of the valve of smaller size than the internal the diameter of the hollow casing, and the selected camera is a ring cavity in the hollow body, located at the valve and communicated to the inlet flow of multicomponent gas-liquid medium through the intake channels made symmetrically to the axis of rotation of the valve, a valve body, and a rod provided with projections under multiple threads of corresponding section, performed on a shaft over a length not less than one-quarter of the axial step in this thread.
