The working principle is that the hydraulic blowout preventer is mainly used for controlling the opening and closing of a flashboard of the hydraulic blowout preventer, the pipe is clamped, meanwhile, the function of shearing an oil pipe at high pressure is realized, the power source automatically starts pressurization when the pressure is set to be insufficient according to the system pressure, and the power source automatically stops pressurization when the set highest pressure value is reached; when the system or the equipment has a fault, the voice prompt is automatically alarmed; the system is stable, safe and reliable.
Before the system works normally, the opening and closing conditions of a first high-pressure stop valve 10 on a working pressure control pipeline and a second high-pressure stop valve 22 on a high-pressure control pipeline are checked, and the first high-pressure stop valve 10 on the high-pressure control pipeline is closed for a long time under the normal condition; the second high-pressure cutoff valve 22 on the working pressure control line is normally opened to operate. It is to be noted that the first high-pressure cutoff valve 10 and the second high-pressure cutoff valve 22 may not be opened at the same time. Immediately after closing the first pressure relief valve 15 on the working pressure control line and the first three-position four-way operation valve 16, the handles are in the neutral state (i.e., closed state).
After the inspection is finished, the working pressure power switch 61 on the working pressure control area 6 is turned on, then the first start button 62 is pressed, the first explosion-proof pressure control starter 19 starts to start the motor and pump set which supplies power to the power pressure source 1 through the second lead 33, the oil level low alarm sensor 34 and the alarm system which are used for displaying the low oil level are arranged on the oil tank 2, the oil level low alarm sensor 34 is connected with the oil tank liquid level display lamp 68 through the third lead 35, when the oil level is low and reaches the lowest position, the alarm is given, and the oil tank liquid level display lamp 68 is red, the oil is pumped into the pipeline, enters the high pressure oil filter 3 from the elbow joint 8, enters the first high pressure check valve 4 on the working pressure control pipeline through the working pressure control pipeline 9 (the oil original circuit is prevented from returning), enters the first high pressure stop valve 10, and then the accumulator set 11 stores the pressure. Pressure is connected with first explosion-proof pressure control starter 19 through first high-pressure main pipe 17 and first low pressure main pipe 18 respectively, and first high-pressure main pipe 17 is connected with the first high pressure manometer 65 of operating pressure control district 6 through first high-pressure auxiliary pipe 36 simultaneously, and first low pressure main pipe 18 is connected with the first low pressure manometer 67 of operating pressure control district 6 through first low pressure auxiliary pipe 37, can directly see high low pressure size at the system panel. The pressure highest value system of the first explosion-proof pressure control starter 19 is set to be MPa, and when the pressure reaches the value, the motor and the pump set of the power pressure source 1 are controlled to stop working; the lowest pressure system is set to be 18.9MPa, and when the pressure is lower than 18.9MPa, the motor and the pump set of the power pressure source 1 are controlled to start working; when the working pressure value in the accumulator group 11 is within the set range value (18.9 MPa-MPa), the first rated high-pressure display lamp 64 and the first rated low-pressure display lamp 66 are in green lamps, which indicates that the system is normal and safe.
If the pressure of the accumulator group 11 is higher than the MPa and reaches 21.5MPa, the first explosion-proof control alarm 20 starts to alarm, and simultaneously the first rated high-pressure display lamp 64 on the working pressure control area 6 is prompted to be red by voice, and the first high-pressure gauge 65 rises, which indicates that the first explosion-proof pressure control starter 19 of the system is out of order and cannot control the motor and the pump set of the power pressure source 1 to stop working. For the safety of the whole device, if the pressure value rapidly rises to 23.1MPa, the first overflow valve 13 (the set pressure value range of the first overflow valve 13 is not more than 23.1MPa, and the closing pressure is not lower than 18.9 MPa) starts overflow and reduces the pressure, and the first closing button 63 is immediately pressed to ensure the safety, so that the first explosion-proof pressure control starter 19 is powered off to stop the operation of the motor and the pump set. While pressing the first alarm stop button 691. And finally, opening the first pressure relief valve 15 to relieve the pressure in the pipeline and then carrying out maintenance.
The accumulator set 11 stores pressure, and when the pressure enters the first pressure regulating and reducing valve 14 through a pipeline to reduce the pressure to 10.5MPa of working system pressure used for controlling the blowout preventer, the working system pressure is output pressure, and the working system pressure is connected with an output pressure gauge 69 through a first pressure output auxiliary pipeline 40. And finally, a first three-position four-way operation valve 16 is used for controlling operations such as opening and closing of a ram block of the blowout preventer, pipe clamping and the like.
When the pipe column is required to be sheared urgently in case of emergency during wellhead control operation, the normal 10.5MPa and 21MPa can not meet the requirements of shearing the pipe column, and the pipe column can be sheared only by the pressure between 21MPa and 25 MPa. It is necessary to close the first high-pressure cut-off valve 10 in the working pressure control line and then open the second high-pressure cut-off valve 22 in the high-pressure control line while closing the second pressure relief valve 26 and the second three-position four-way operation valve 27 with the handle in the neutral state (i.e., closed state).
After the inspection is finished, the high-voltage power switch 71 on the high-pressure control area 7 is turned on, the second start button 72 is pressed, the second explosion-proof pressure control starter 30 starts to work by supplying power to the motor and the pump set of the power pressure source 1 through the seventh lead 42, oil is sucked from the oil tank 2 and is pressed into the pipeline, the oil enters the high-pressure oil filter 3 from the elbow joint 8, enters the second high-pressure check valve 5 on the high-pressure control pipeline (for preventing the oil from returning from the original path) through the high-pressure control pipeline 21 and then enters the first high-pressure check valveTwo high pressure shut off valves 22 and a high pressure manifold 23. The pressure is respectively connected with the second explosion-proof pressure control starter 30 through a second high-pressure main pipeline 28 and a second low-pressure main pipeline 29, the second high-pressure main pipeline 28 is connected with a second high-pressure gauge 75 on the high-pressure control area 7 through a second high-pressure auxiliary pipeline 43, the second low-pressure main pipeline 29 is connected with a second low-pressure gauge 77 on the high-pressure control area 7 through a second low-pressure auxiliary pipeline 44, and the high-low pressure can be directly seen on a system panel. The second burst pressure control actuator 30 pressure peak system setting is 250 -0.7When the pressure reaches the value, controlling the power pressure source 1 to stop the motor and the pump set; the lowest pressure value system is set to 23.1MPa, and when the pressure is lower than 23.1MPa, the motor and the pump set of the power pressure source 1 are controlled to start working; when the working pressure value in the high-pressure collecting pipe 23 is within the set range value (23.1 MPa-25)0 -0.7MPa), the second rated high voltage indicator lamp 74 and the second rated low voltage indicator lamp 75 are in green, indicating that the system is normal and safe.
If the high pressure manifold 23 is above 25 f0 -0.7When the MPa reaches 25.5MPa, the second explosion-proof control alarm 31 starts to alarm, and simultaneously, the voice prompts that a second rated high-pressure display lamp 74 on the high-pressure control area 7 is a red second high-pressure gauge 75 to rise, which indicates that the second explosion-proof pressure control starter 30 of the system has a fault and cannot control the motor and the pump set of the power pressure source 1 to stop working. For the safety of the whole device, if the pressure value is rapidly increased to 28.5MPa, the second overflow valve 25 (the set pressure value range of the second overflow valve 25 is not more than 28.5MPa, and the closing pressure is not lower than 23.1 MPa) starts overflow and pressure reduction, and the second closing button 73 is immediately pressed to ensure the safety, so that the second explosion-proof pressure control starter 30 is powered off to stop the operation of the motor and the pump set. While a second alarm stop button 78 is pressed. Finally, the second pressure relief valve 26 is opened to relieve the pressure in the pipeline for maintenance.
During normal operation, the pressure in the high-pressure collecting pipe 23 enters the second three-position four-way operating valve 27 through a pipeline to operate and control the instantaneous high-pressure shearing pipe column operation of the shearing ram of the blowout preventer. After the pipe column shearing operation is finished, the second closing button 73 is closed again to stop the power supply of the second explosion-proof pressure control starter 30, the motor and the pump set of the power pressure source 1 stop working, then the high-voltage power switch 71 is closed, the second pressure relief valve 26 is opened to relieve the pressure in the pipeline, and finally the second high-voltage stop valve 22 is closed.
The safety combined blowout preventer control device system is mainly different from a conventional control device system in that a high-pressure control area is added and combined with a working pressure control area to implement separate operation, and high-pressure operation cannot be implemented under special conditions and accidental high-pressure damage to systems and equipment is avoided; the system has a safety alarm voice prompt, and a separate alarm voice prompt is set according to a control area, so that accidents caused by equipment or system faults are avoided; the overflow valve has an overflow pressure reduction function, and the overflow valve is automatically opened after the pressure reaches an alarm function, so that the pressure relief function is implemented, and the safety of equipment personnel is ensured; the system has stable pressure and high safety, and has the functions of safe starting and safe shutdown; energy conservation, emission reduction, safety, environmental protection and strong applicability; the high-pressure working pressure is combined together and simultaneously separated to operate, and the functions of safety alarm voice prompt, safety start, safety shutdown, safety environmental protection and the like are combined together, so that the key problem that emergency control cannot be performed under special conditions is solved.
