The possibility of closing the well 1 in the sequence side valve 3 - the nadkasny valve 4 - the underground valve-cutter 5 is provided automatically by the commands of the station control panel, in the remote control mode by the operator’s command from the remote central control station and in manual mode, and the opening is in sequence : underground valve-shutter 5 - nadkorna valve 4 - side valve 3 provide preferably in manual control mode.

Well control is as follows.

At the moment when the control station starts operating, the entire hydraulic system is filled with the working fluid - the working medium.

The required working pressure of the working medium in the control lines of the station is created and maintained by a pump-accumulator plant 7.

The working medium from the tank 37 with a volume of about 200 liters is fed through a coarse filter 40 and a valve to the inlet of an electric pump 38, which is driven by an electric motor 39. At the outlet of the pump 38 after the crane, the working medium is passed through the filter 41.

The safety valve 42 is adjusted to a predetermined operating pressure of 21 MPa and, when the predetermined pressure is exceeded, a high-pressure line 10 is connected to the cavity of the tank 37.

- 16 013310 allows the discharge of excess volume of working medium through the bypass drain line 33.

Through a check valve 43 from the high-pressure line 10, the working medium is supplied to the collector 44 and the modules 45 of the power functional pneumohydro-accumulator 9 are filled to store the necessary supply of working medium under pressure, each module 45 having a volume of 40-50 liters.

After filling the power of the functional pneumohydroaccumulator 9, the working medium through the pipelines is fed to the power lines 14-17 of the functional control of the actuators of the locking bodies, the underground shut-off valve, the throttle valve and the logic control line 18.

Using the pressure regulator 13 in the power line 16 of the functional control of the actuator of the underground slam-shut valve 5, the pressure in the high pressure line 10 is reduced from 21 MPa to a pressure of three or four times the pressure at the outlet of the multiplier 32, which provides the working pressure in the power line 16 of the functional control the actuator of the underground valve-slam-shut 5, equal to 24 MPa (280 kgf / cm ² ). The safety valve 47 is adjusted to a predetermined operating pressure of 28 MPa and, when the predetermined pressure is exceeded, the said line 16 is connected to the cavity of the tank 37 and the excess volume of the working medium is discharged via the bypass drain line 33.

Using pressure regulators 12 reduce the pressure in the power line 17 of the functional control of the actuator of the throttle valve 6 and in the logic control line 18 to a working pressure of 4 MPa (40 kgf / cm ² ), and in the power lines 14, 15 of the functional control, respectively, the lateral actuators and nadkorny gate valves 3, 4 - up to 14 MPa (140 kgf / cm ² ). The safety valves 47 adjust to a predetermined working pressure of 4 MPa and, when the set pressure is exceeded, these lines are connected to the cavity of the tank 37, and the excess volume of the working medium is discharged via the bypass drain line 33.

In the station control unit 11, the working medium at a pressure of 4 MPa in the logic control line 18 is fed to the inlet of the normally closed hydraulic distribution valve 28, which is designed to relieve control pressure in case of fire. After filling the line 34 of the fuse-link 26, the hydraulic distribution valve 28 is opened and the working medium enters the inlet of the normally-closed hydraulic distribution valve 29, designed to relieve control pressure when the low and high pressure control valve 27 is activated in line 35 of the valve. Then the working medium passes through normally open distribution valve 30, intended for remote activation and shutdown of the entire well, and distribution valve 31, intended for manual emergency shutdown of the entire well by means of an emergency shutdown button.

After the distribution valve 31, the working medium is fed to the inlet of the normally closed distribution valve 49 with hydraulic actuator and manual override.

When the line 34 of the fuse-insert 26 is filled, the pressure relay 48 outputs a signal to the central control panel.

When line 35 of low and high pressure control valve 27 is full, another pressure relay 48 also provides a signal to the central control panel.

Next, in order to open a well, you need to perform the following sequence of actions:

pull the handle of the distribution valve 49, which is placed on the power supply, and the working medium through the check valve 56 is fed to the actuator of the regulator valve 19, which opens and the working medium from the power line 16 of the functional control of the actuator of the underground shut-off valve 5 is fed to its actuator .

The opening nadkorny valve 4;

pull the knob of the distribution valve 51, which is placed on the power supply, and the working medium through the normally open solenoid valve 52 enters the actuator of the regulator valve 21, which opens and the working medium from the power lines 14, 15 of the functional control, respectively, actuators of the side and pickled valves 3 4 enters the actuator of the side valve 3. The side valve opens 3. The reservoir fluid from well 1 flows through the open underground shutoff valve 5 into the font These fittings 2.

The closure of the well 1 can be carried out by the automatic protection system or by the system of remote activation and shutdown of the well. In addition, there is the possibility of autonomous control of a regulating throttle valve.

- 17 013310

At the standard pressure values in lines 35, 34, respectively, of the low and high pressure control valve 27 and the fusible insert 26 of the well, the control valve 29 is in the open position. When the working medium pressure drops or increases in the above-mentioned lines below or above the set (specified) values, the control valve 29 moves to the closed position, the working medium is discharged from the power lines 19-16 of the functional control, respectively, to the lateral actuators, nadkorny valves 3, 4 and underground valve-slam-shutter 5. Throttles 25 with control pneumo-hydroaccumulators 24 serve to regulate the time interval during the sequential closing of the closure organs of the well 1.

In the event of a fire when the ambient temperature rises at the wellhead above the set value (in a fire situation), the working medium is discharged from line 34 of the fuse-link 26, after which the control valve 28 moves to the closed position, the working medium is discharged from power lines 14- 16 functional control, respectively, side, nadkorny valves 3, 4 and underground valve-slam-shutter 5. Throttles 25 with control pneumohydroaccumulator 24 serve to regulate the time interval sequential closing of shut-off elements of the well 1.

System of remote shutdown of a well.

In the station control unit 11, a distribution valve 30, made solenoid, and a remote shut-off solenoid valve 52, controlled from the station's control panel or from the central control panel, are installed.

When a 24V signal is applied to the electric drive of the distribution valve 30, the side valve 3, the snubbed valve 4 and the underground slam-shut valve 5 are remotely closed.

When a 24V signal is applied to the actuator of the remote control valve 52, the side gate valve 3 is remotely closed.

Control throttle valve control.

When voltage is applied to the first electromagnet of the three-position distribution valve 53, the working medium under pressure up to 4 MPa from the power line 17 of the functional control of the actuator of the throttle valve 6 is fed into its actuator. From the positioner installed on said valve, an analog signal is output to the control cabinet 36 or to the central control panel. Then from the cabinet 36 receives a signal at the first electromagnet (voltage is removed) and the three-position control valve 53 is transferred to the neutral position. If it is necessary to reduce the flow rate of the produced fluid from the control cabinet 36, a signal is sent to the second electromagnet of the three-position distribution valve 53, the working medium is reset to the specified parameters.

Thus, the proposed methods for controlling the flown armature and underground equipment of gas, gas condensate, oil and gas and oil fields provide increased reliability and trouble-free operation, respectively, gas, gas condensate, oil and gas and oil fields.
