Description

The invention relates to the oil and gas industry, in particular to the field of pumping technology, mainly to installations for gas production.

Application: gas production.

The device consists of: a pressure creation device, pumping pumps installed in a sealed housing, a retractable fixation system, a pipe folding system, a rotational mechanism for drilling blades, drilling blades, a blade deployment system, a control unit, a unit for monitoring and operating systems, a mechanical lock, as well as pipes, transceiver, grounding, control panel.

The prototype of the proposed invention is a drilling method with control of the operating mode of a hydraulic downhole motor in downhole conditions, including measuring pressure readings in the injection line under load and without load on the bit, maintaining a constant difference in the measured pressure readings, determining the maximum permissible value of the feed rate, and measuring the feed rate bit and reducing it to acceptable values (1).

The disadvantage of the prototype is that the method of controlling the operation of the hydraulic downhole motor is not effective enough, takes into account a limited number of operating parameters of the drilling rig during the drilling process and does not provide adjustments to the wellbore trajectory during the drilling process.

The prototype of the proposed invention is a drilling tool feed device that implements a drilling method with automatic control of the drilling tool feed, based on maintaining a constant torque on the bit and reducing fluctuations in the bottom of the drill string due to controlled pressure in the manifold line (1). This method does not limit the feed rate of the drilling tool, which causes premature wear of the bit due to its impact on the bottom and overload during a sharp change in rocks of different hardness. Exceeding the drilling speed over the upward flow rate of the drilling fluid often leads to clogging of the annular space with drilled rock particles.

The disadvantage of this method is that it does not adjust the well trajectory.

The prototype of the proposed invention is a drilling method with automatic control of the feed of a drilling tool during the drilling process (1), including measuring the pressure of the drilling fluid in the manifold line, comparing it with the specified and maximum permissible values and controlling the actuator for feeding the drilling tool depending on the results of the comparison, carrying out measurements of additional operating parameters of drilling, idle parameters, increasing or decreasing the feed rate of the drilling tool.

The disadvantages of this drilling method are low reliability associated with the need to collect information from a large number of sensors, and high complexity of setup. The method also does not provide for drilling inclined wells with adjustment of their trajectory.

Operating principle of the pressure creation device:

The electromagnet (22) is turned on, which extends the entire structure, using a magnetized plate (21) and a travel mechanism (17), which moves along the guides (18). From the base (23), the blades (24) are extended into the central area of the device. The electric rotator (16) is turned on, which rotates the beam (15) with the attached beam (20) using the connecting bowl (19) on which the blades (24) are fixed. The work process is in progress. The electric rotator (16), made with the ability to regulate power, allows you to increase or decrease the speed of rotation of the blades (24) used to create the pressure necessary to transport gas through the gas transmission system. When performing work, the electric rotator (16) and the electromagnet (22) are turned off. The device, with the help of a spring placed on the base (23), returns to its original position.

Operating principle of ground pumps:

The pumping pumps are installed in a sealed housing (26). An electromagnet (25) is built into the sealed housing (26), which, when turned on, moves the magnetized plate (27) with a fixed beam (29) with a built-in pumping part (33). The guide rings (28) produce a uniform movement of the beam (29). The pump part (33) at the ends is connected by a rubber elastic wall (32), which creates a seal inside the pump, but allows the pump part (33) to move. When the electromagnet (25) is turned on, the magnetized plate (27), beam (29) and pump part (33) move. When the pump part (33) reaches the fixation angle (31), the electromagnet (25) is turned off and the spring (30) returns the beam (29) combined with the running elements to its original position, this allows gas to rise from the ground. A clock electromagnet (25) is installed in the pumping pump, which is designed to be adjustable in power and speed to set the pumping pump to the value necessary to lift gas from the ground when the gas is located at different depths.
