DETAILED DESCRIPTION

[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0036] The hydraulic tubing tongs are special machines used to make or break out tubing during well repair operations in oil and gas fields. The hydraulic tubing tongs include a tongs body, a motor and a hydraulic tubing tongs control device. The tongs body has jaws whose size needs to match the size of the tubing so that the jaws can clamp the tubing.

When controlling the hydraulic oil pipe clamp, the operator can operate the reversing handle to control the manual reversing valve, thereby making the motor rotate forward or reverse; the operator can also operate the manual shift switch to realize the movement of the shift switch between different gears.

[0038] However, when making or breaking the oil pipe, the operator needs to be within the oil and gas wellhead and the rotation range of the hydraulic tubing clamp to operate, which makes it easier for mechanical injury accidents to occur, resulting in low safety of the hydraulic tubing clamp control device.

[0039] The embodiments of the present application provide a hydraulic oil pipe clamp control device and an operating method thereof, which can solve the problems existing in the above-mentioned related technologies.

[0040] Figure 1 is a structural schematic diagram of a hydraulic oil pipe clamp control device provided in an embodiment of the present application, such as Figure 1 As shown, the hydraulic oil pipe clamp control device includes: a remote control component 11, a first control component 12, a first solenoid valve 13 and a reversing valve 14.

The first control component 12 is used to receive the control signal output by the remote control component 11, and control the first solenoid valve 13 based on the control signal. The first solenoid valve 13 has at least two liquid circuits and a valve core located on the solenoid valve body. The first control component 12 of the valve body can convert the received control signal into an electric current, and control the movement of the valve core of the first solenoid valve 13 through the electric current, thereby opening or closing different liquid circuits on the first solenoid valve 13.

[0042] like Figure 2 As shown, Figure 2 yes Figure 1 The structural schematic diagram of the reversing valve in the hydraulic oil pipe clamp control device shown in the figure, the reversing valve 14 includes a valve body 148, a liquid supply hole 145, a piston 149, two drive pipelines (1410 and 1411) and two control pipelines (141 and 142), the valve body 148 includes a valve chamber 1481, the piston 149 is located in the valve chamber 1481, and the valve chamber 1481 is divided into a first regulating chamber 14811 and a second regulating chamber 14812, the piston 148 and the valve chamber 1481 constitute a first circuit and a second circuit, and the reversing valve 14 also includes a return hole 146.

[0043] like Figure 3 As shown, Figure 3 yes Figure 1 As shown in the external structure diagram of the hydraulic oil pipe clamp control device, the first regulating chamber and the second regulating chamber are respectively connected to the liquid supply pipeline through two control pipelines (141 and 142), and the first solenoid valve 13 is installed on the two control pipelines (141 and 142) to control the liquid supply pipeline to be connected to one of the two control pipelines (141 or 142), and the liquid supply pipeline is used to provide power fluid.

[0044] like Figure 1 As shown, the workover rig at the oil and gas well site includes a power device 31, which can provide hydraulic power for the hydraulic oil pipe clamp control device. The power device 31 can include a distribution valve 311, a hydraulic pump 312, a filter element 313, a check valve 314 and an oil tank. Among them, the hydraulic pump 312 is used to provide hydraulic power, and the liquid supply pipeline 143 can be connected to the hydraulic pump 312 on the workover rig at the oil and gas well production site through the distribution valve 311. The distribution valve 311 can be used to control the opening and closing of the liquid supply pipeline. The other end of the hydraulic pump 312 is connected to the oil tank through the filter element 313 and the check valve 314. The filter element 313 can filter impurities in the liquid in the oil tank to prevent the impurities in the liquid from damaging the hydraulic pump 312. The check valve 314 can prevent the liquid from flowing back to the hydraulic pump 312 to prevent the hydraulic pump 312 from being damaged by the reversal of the hydraulic pump 312. The oil tank can be used to collect the power fluid of the hydraulic oil pipe clamp device.

[0047] like Figure 4 As shown, Figure 4 yes Figure 2 The schematic diagram of the first circuit of the reversing valve shown in the figure, the power fluid in the first regulating chamber 14811 pushes the first regulating piston 14813 to move, and the piston 149, under the push of the first regulating piston 14813, makes the first circuit 1482 connected with the motor 22 of the hydraulic oil pipe clamp, and blocks the second circuit and the liquid supply pipe 143. At this time, the second circuit can be connected with the return liquid pipe 144 to form a hydraulic circuit of the reversing valve 14 and the motor of the hydraulic oil pipe clamp, so that the motor of the hydraulic oil pipe clamp continues to rotate in the clockwise direction, that is, the motor of the hydraulic oil pipe clamp is controlled to rotate forward.

[0048] Or, if Figure 5 As shown, Figure 5 yes Figure 2 The schematic diagram of the second circuit of the reversing valve shown in the figure shows that the power fluid in the second regulating chamber 14812 pushes the first regulating piston 14814 to move, and the piston 149, under the push of the second regulating piston 14814, makes the second circuit 1483 connected with the motor of the hydraulic oil pipe clamp, and blocks the first circuit and the liquid supply pipeline 143. At this time, the first circuit can be connected with the return liquid pipeline 144 to form a hydraulic circuit of the reversing valve 14 and the motor 22 of the hydraulic oil pipe clamp, so that the motor of the hydraulic oil pipe clamp continues to rotate in the counterclockwise direction, that is, the motor of the hydraulic oil pipe clamp is controlled to reverse.

[0049] The embodiment of the present application is explained by taking the example that the motor rotates clockwise as forward rotation and counterclockwise as reverse rotation, but the motor can also rotate clockwise as reverse rotation, and counterclockwise as forward rotation, and the embodiment of the present application does not limit this.

[0050] The hydraulic oil pipe clamp control device provided in the embodiment of the present application can, after the remote control component sends a control signal, the first control component controls the first solenoid valve based on the control component, and then the first solenoid valve controls the flow direction of the power fluid in the circuit of the reversing valve to make the motor of the hydraulic oil pipe clamp rotate forward or reverse, that is, the rotation of the motor of the hydraulic oil pipe clamp can be remotely controlled, and the function of controlling the hydraulic oil pipe clamp to buckle or unclip the oil pipe can be realized.

[0051] To summarize, the embodiment of the present application provides a hydraulic oil pipe clamp control device including a remote control component, a first control component, a first solenoid valve and a reversing valve. After the remote control component sends a control signal, the first control component controls the first solenoid valve based on the control signal. The first solenoid valve controls the movement of the piston of the reversing valve so that any one of the two circuits of the reversing valve is connected to the motor of the hydraulic oil pipe clamp, so that the motor of the hydraulic oil pipe clamp rotates forward or reverse, thereby realizing remote control of the hydraulic oil pipe clamp. This can solve the problem of low safety when the hydraulic oil pipe clamp control device in the related art is in use and the operator is within the wellhead of the oil and gas well and the rotation range of the hydraulic oil pipe clamp to operate, thereby achieving the effect of improving the safety of the hydraulic oil pipe clamp control device.

[0052] Optionally, the hydraulic oil pipe clamp control device also includes a high-low gear conversion component and a second control component, the high-low gear conversion component includes a shift fluid cylinder and a second solenoid valve, the second control component is wirelessly connected to the remote control component and electrically connected to the second solenoid valve, the shift fluid cylinder is connected to the second solenoid valve, the shift fluid cylinder is installed on the shift switch of the hydraulic oil pipe clamp, the second solenoid valve is connected to the fluid supply pipeline, and the second control component is used to control the fluid supply pipeline through the second solenoid valve to supply fluid to the shift fluid cylinder to push the shift switch of the hydraulic oil pipe clamp.

[0053] Optionally, the hydraulic oil pipe clamp control device also includes a jaw alignment monitoring component, which is installed on the clamp body of the hydraulic oil pipe clamp. The jaw alignment monitoring component includes a visual probe and a video signal transmitting unit, which is used to obtain a position image of the hydraulic oil pipe clamp and send a video signal to the remote control component.

[0054] Optionally, the hydraulic oil pipe clamp control device also includes a torque transmission component, which is connected to the fluid supply pipeline and is used to convert the hydraulic signal into an electrical signal and transmit it to the remote control component.

[0055] Optionally, the remote control component includes a direction control button, a gear control button, a signal transmitting unit, a signal receiving unit and a display unit. The direction control button is used to input direction change instructions, the gear control button is used to input gear change instructions, the signal transmitting unit is used to output instructions, the signal receiving unit is used to receive electrical signals and video signals from the jaw alignment monitoring component and the torque transmission component, and the display unit is used to display the position image and torque value of the hydraulic oil pipe clamp.

[0056] Optionally, the first control component includes a first signal receiving unit and a first signal conversion unit, the first signal receiving unit is used to receive the switching control signal output by the remote control component, and the first signal conversion unit is used to convert the received switching control signal into current to control the first solenoid valve.

[0057] Optionally, the second control component includes a second signal receiving unit and a second signal conversion unit, the second signal receiving unit is used to receive the shift control signal output by the remote control component, and the second signal conversion unit is used to convert the received shift control signal into current to control the second solenoid valve.

[0058] Optionally, the first solenoid valve and the second solenoid valve are both three-position four-way solenoid valves.

[0059] Optionally, when the torque force value exceeds a specified safety value, a reminder is displayed on the display unit.

[0060] Alternatively, if Figure 1 As shown, the hydraulic oil pipe clamp control device also includes a high-low gear conversion component 15 and a second control component 16. The high-low gear conversion component 15 includes a shift cylinder 151 and a second solenoid valve 152. The second control component 16 is wirelessly connected to the remote control component 11 and electrically connected to the second solenoid valve 152. The shift cylinder 151 is connected to the second solenoid valve 152.

[0061] like Figure 6 As shown, Figure 6 This is a structural schematic diagram of the hydraulic oil pipe clamp control device provided in an embodiment of the present application installed on the hydraulic oil pipe clamp, the shift cylinder 151 is installed on the shift switch 21 of the hydraulic oil pipe clamp, the second solenoid valve 152 is connected to the liquid supply pipeline, and the second control component is used to control the liquid supply pipeline to supply liquid to the shift cylinder 151 through the second solenoid valve 152 to push the shift switch 21 of the hydraulic oil pipe clamp.

[0062] That is, through the operation of the high and low gear conversion component, the shift switch can be driven to operate, so that the shift switch can operate between different gears, thereby realizing the effect of remote shifting of the hydraulic tubing pliers. The gears can include high gear and low gear. When the shift switch is in low gear, the motor speed of the hydraulic tubing pliers is slower, and when the shift switch is in high gear, the motor speed of the hydraulic tubing pliers is faster.

[0063] Optionally, the hydraulic oil pipe clamp control device also includes a jaw alignment monitoring component, which is installed on the jaw alignment monitoring device of the hydraulic oil pipe clamp. The jaw alignment monitoring component includes a visual probe and a video signal transmitting unit, which are used to obtain the position image of the hydraulic oil pipe clamp and send a video signal to a remote control component, wherein the jaw body of the hydraulic oil pipe clamp has a jaw, and the visual probe is installed on the jaw body, and the visual probe is opposite to the jaw, so as to obtain a real-time image of the jaw position, and send the real-time image to the remote control component through the video signal transmitting unit, so that the operator can make a visual judgment on the holding condition of the jaws on the oil pipe, which can avoid the hydraulic oil pipe clamp from getting stuck when clamping or releasing the oil pipe.

[0064] Optionally, the hydraulic oil pipe clamp control device also includes a torque transmission component, which may include a pressure sensor and a signal sending unit. The pressure sensor can be connected to the fluid supply pipeline to obtain the pressure signal of the fluid supply pipeline. The signal sending unit can be used to convert the hydraulic signal into an electrical signal and transmit it to the remote control component.

[0065] Torque is a kind of torque that makes an object rotate. The torque of hydraulic tubing pliers refers to the torque output from the motor of the hydraulic tubing pliers. Under the condition of fixed power, the torque is inversely proportional to the speed of the motor. The faster the speed, the smaller the torque. Conversely, the slower the speed, the greater the torque. The torque reflects the load capacity of the hydraulic tubing pliers within a certain range.

[0066] like Figure 1 As shown, the power device 31 further includes a relief valve 315, which can be installed on the liquid supply pipeline 143, that is, the working torque of the hydraulic oil pipe clamp can be controlled by limiting the liquid supply pressure through the relief valve 315. In a stable working state, there is a linear relationship between the output torque of the hydraulic oil pipe clamp and the liquid supply pressure of the liquid supply pipeline 143. Therefore, the magnitude of the output torque of the hydraulic oil pipe clamp can be determined by obtaining the liquid supply pressure of the liquid supply pipeline 143.

[0067] However, in actual operation, the expected torque control effect may not be achieved. Sometimes, excessive make-up torque may damage the threads of the oil pipe, posing a risk of breakage and sticking of the threads, while insufficient make-up torque may cause the oil pipe to come loose. Therefore, by connecting a torque transmission device to the liquid supply pipeline, the hydraulic signal of the liquid supply pipeline can be obtained in real time, and the torque transmission device can convert the hydraulic signal into an electrical signal and transmit it to the remote control component.

In this way, the operator can remotely control the first control assembly and the second control assembly at the remote control assembly, which can reduce the labor intensity of the operator while providing the safety of the hydraulic oil pipe clamp operating device. In addition, the operator can watch the images of the jaws and the oil pipe of the hydraulic oil pipe clamp in real time through the display unit, so that the operator can perform the next operation according to the actual situation at the production site.

[0069] Optionally, when the torque value exceeds a specified safety value, a reminder is displayed on the display unit. The specified safety value is 12MPa. The display unit on the remote control component can also display the torque value. When the torque value is greater than 12MPa, a safety reminder is displayed on the display unit to enable the operator to reduce the torque of the hydraulic oil pipe clamp in time to avoid excessive torque and damage to the thread of the oil pipe.

The second control component 800 includes a second signal receiving unit 810 and a second signal conversion unit 820. The second signal receiving unit 810 is used to receive the shift control signal output by the remote control component. The second signal conversion unit 820 is used to convert the received shift control signal into an electric current to control the second solenoid valve. In this way, the remote control component can be wirelessly connected to the second control component 800.

[0072] Optionally, the first solenoid valve and the second solenoid valve are both three-position four-way solenoid valves. When the coil is energized or de-energized, the operation of the valve core will cause the fluid to pass through the valve body or be cut off, so as to achieve the purpose of changing the direction of the fluid, and the three-position four-way solenoid valve has three working positions and four passages. The power supply voltage of the first solenoid valve and the second solenoid valve is 24V, which can be connected to the low-voltage power supply of the well repair equipment at the oil and gas well production site.

Fig. 9 As shown, Fig. 9 It is a schematic diagram of the structure of the connecting plate shown in the embodiment of the present application. The connecting plate 17 has four channels, which are respectively connected to the four passages of the first solenoid valve. The first solenoid valve can control the opening and closing of the four channels in the connecting plate 17. The two channels (171 and 172) in the connecting plate 17 can be connected to the two control pipelines (141 and 142) of the reversing valve. The two control pipelines (141 and 142) can be U-shaped connecting pipes. The connecting plate 17 has an overflow hole 175, which is connected to the third channel 173 of the connecting plate 17.

[0080] Step 1003: The first solenoid valve controls the movement of the piston of the reversing valve through two control pipelines to connect the first circuit with the motor of the hydraulic oil pipe clamp or the second circuit with the motor of the hydraulic oil pipe clamp, so that the motor of the hydraulic oil pipe clamp rotates forward or reversely.

[0081] To summarize, the embodiment of the present application provides an operating method for a hydraulic oil pipe clamp control device. After the remote control component sends a control signal, the first control component controls the first solenoid valve based on the control signal. The first solenoid valve controls the movement of the piston of the reversing valve so that any one of the two circuits of the reversing valve is connected to the motor of the hydraulic oil pipe clamp, so that the motor of the hydraulic oil pipe clamp rotates forward or reverse, thereby realizing remote control of the hydraulic oil pipe clamp.
