Adnaznachna to control and process automation.

Known information technology drilling complex according to the book of Mr. Molchanov A. geophysical Measurement and process parameters in the process of drilling wells, -M.: Nedra, 1983, p 168-169.

This complex consists of the telemetry system containing, in turn, power supply, directional sensors, the electronic unit. The complex provides transmission to the surface only survey data. Other downhole and technological parameters are not controlled.

Known information technology drilling complex according to the book of A. Bulatov I. and other Reference drilling engineer. -M.: Nedra, 1985, so 2, S. 9, Fig. 36.

This set contains a processing unit and information visualization (block sensor and logger), ground-based technological sensors. Downhole parameters not monitored, which is one of the disadvantages of the complex, because the knowledge of many parameters in the immediate vicinity of the downhole motor (speed turbines, axial force, torque) is more important than the same information obtained in the upper part of the drill pipe string. The weight of the drill pipe may not be equal to the axial load on the bit, e.g., due to bending of the drill is e measurements. The second drawback is that data processing is slow, inaccurate and seems much too clearly. The third disadvantage is that the values of all parameters displayed on analog devices and recorders, and analysis of situations encountered during drilling, depends on the experience of the technician operating the equipment. The assessment of the situation requires complex calculations and long-term analysis. This is especially critical in emergency situations requiring rapid decisions. This task can be solved only with the automation of the drilling process.

The closest analogue of the claimed invention is an information technology geosteering complex book Molchanov, A. A. geophysical Measurement and process parameters in the process of drilling wells. -M.: Nedra, 1983, S. 178-184.

This complex contains the driller's console, block processing and visualization, made in the form of interconnected converting complex and computer monitor downhole telemetry system, a torque sensor, ground the sensor, flow sensor and pressure sensor, and installed in the casing downhole telemetry system block inclinometry >/p>The task of the invention is the increased efficiency in delivering technology solutions and automation of the drilling process, improving the accuracy and reliability of information recording, and increases the speed of processing and transmission.

The solution of the stated problem is achieved due to the fact that the information technology geosteering complex containing the driller's console, block processing and visualization, made in the form of interconnected converting complex and computer monitor downhole telemetry system, a torque sensor, ground the sensor, flow sensor and pressure sensor, and installed in the casing downhole telemetry unit to the directional and the sensor axial load is supplied by the ground sensor density sensor having a gas phase, a level sensor mud set in the receiving tank, the Executive bodies of the control system connected to the output of the computer, while ground-based flow sensor, pressure sensor, density sensor, and the sensor of the presence of the gas phase is installed in the discharge line of the drilling fluid and the torque sensor is installed in the casing downhole telemetry system.

Nali is on the drilling process and to improve the measurement accuracy. Mainly this is achieved by using a computer and a large number of sensors, giving almost a full view of ground-based and technological parameters of the drilling process. In addition, the use of special software was able to handle an array of information and present it on the screen, and the driller's console in a very visual and easy to analyze, and to enter into the program control actions during emergency situations. The essential features described in the claims, constitute a set of necessary and sufficient for the implementation of the project, because the presence of any one or more, but not complete will not allow you to get the desired result. The use of a computer or only ground sensors will not lead to the claimed technical result.

Configurations using one or more Executive agencies listed in the table.

The operation of the device depends on its configuration.

1. In the case of applications for electromagnetic communication channel (EMK).

During the drilling of the pump 5, which is on the discharge line 7 delivers the drilling fluid to the mud motor and makes it work. Survey parameters with block inclinometry 34 and downhole parameters from sensors axial load 30 and torque 31 and turns the turbine 32 via the transmitting module 33 in the form of an electromagnetic signal fed to the antenna 15 and then to the receiving device 16 and the computer 17. Signals from ground-based technological sensors 8, 10, 11, 12, 13, 21 and 29 are fed to the entrance of the Converter system 18 and further input into the computer 17, which is converted and processed and transmitted simultaneously on the monitor 35 and the driller's console 38, if necessary, and a printer 36. On the monitor 35 information promptly, efficiently and clearly communicated to the contractor Geophysics, and on the driller's console 38 of this information seems to be establecida mainly survey data.

Converter system 18 converts the readings from all ground sensors into a signal acceptable to the computer 17. Sensors installed in the casing downhole telemetry systems transmit information to the surface via the transmitting module 33 to the antenna 15, the receiving device 16 and then into the personal computer 17.

The program information processing from the process sensor 47 (Fig. 2) processes all the information received from the sensors to represent originally in digital form, then for visualization in the form of tables, graphs and charts on the monitor 35 and, in addition, calculates and outputs data obtained by mathematical transformation to the measured parameters, for example the deviation from the trajectory. The program of developing technical solutions 48 performs more complex logical and mathematical transform information to develop recommendations for the management of the drilling process. Control program 51 directly delivers the control signals to the Executive bodies of the management system, which includes the pump 6, the drive of the winch 18, the drive of the rotor 25 and the drive preventer 28. Possible to issue a warning (sound and light) signals when the accident at the pump 6, the winch drive 18, the drive of the rotor 25 and the drive preventer 28. Each of these control actions can be implemented either separately or together in any combination. Feedback between the computer 17 and a downhole telemetry system 3 is carried out by acting on the control valve 14 and parcel of the control pulse in the hydraulic channel. This relationship can be used, for example, to turn on or off the power source 4.

If the pulsator 43 creating hydraulic pulses mud, information about the survey parameters and downhole technology sensors can be transmitted via hydraulic communication channel to the pressure sensor 10 and further to converting complex 18 and the computer 17. However, you can use either one hydraulic channel or both channels of communication: hydraulic and electromagnetic for duplication, transmission or parallel send different data. According to information from flow sensors 11, density 12 and the sensor of the presence of the gas phase 13 flowing through the Converter Alu connection to the pressure sensor 10. It is necessary to consider the impact of the characteristics of the drilling fluid on the speed of propagation of the hydraulic waves in the fluid (mud) to avoid distortion of the results.
