DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] Reference Figure 1-Figure 3 , an electric energy storage type intelligent and efficient pressure device, comprising: an electric energy storage system 1, an electric power system 2, a pressure source system 3 and a PLC data acquisition system 4, the electric energy storage system 1 comprising an external power supply interface 1.1 and an energy storage battery pack 1.2, the external power supply interface 1.1 being electrically connected to the energy storage battery pack 1.2, an intelligent allocation control display 1.3 being fixedly mounted on the side wall of the energy storage battery pack 1.2, a rectifier 1.4 being fixedly mounted on the intelligent allocation control display 1.3, the intelligent allocation control display 1.3, the rectifier 1.4 and an output circuit 1.5 being electrically connected, and an output circuit 1.5 being fixedly mounted between the electric energy storage system 1 and the electric power system 2; When using the electric energy storage type intelligent high-efficiency pressurized device, first check whether the external power supply of the electric energy storage system 1 and the electric power system 2 is securely connected. At the same time, check whether the pipeline connection of the pressurized pressure source system 3 and the connection of each pump and valve meet the relevant requirements. Check whether the pressure input and output pressure sensors of the PLC data acquisition system 4 are within the validity period of the test. If they are found to be invalid or expired, stop using them immediately and replace them. At the same time, check whether the connector is firm and the connection direction of the connector cannot be inverted, otherwise the display will not be able to be displayed. The PLC data acquisition system 4 includes an operating console 4.1, a data acquisition display 4.2, an input pressure sensor 4.3, a safety semi-sealed output pressure sensor 4.4, a safety fully sealed output pressure sensor 4.5, a safety slip output pressure sensor 4.6, a safety ring seal output pressure sensor 4.7, an explosion-proof pressure controller 4.8, and a high-pressure valve group 4.9. The operating console 4.1 is equipped with a safety semi-sealed switch, a safety fully sealed switch, a safety slip switch, and a safety ring seal switch. Pay attention to the pressure level of the pressurized device and select a suitable explosion-proof pressure controller 4.8 to control the working pressure of the pump group. It should be installed and used according to the requirements of well control regulations. Debug the minimum pressure start and maximum pressure stop, and check the sensitivity at the same time; The pressurized pressure source system 3 includes a high-pressure gear pump 3.1, a hydraulic oil tank 3.2, a hydraulic oil radiator 3.3, a pump oil inlet pipe 3.4, a pump oil outlet pipe 3.5, an accumulator assembly 3.6, a radiator motor 3.7, and an operating console input pipe 3.8. The pressurized pressure source system 3 is fixedly connected to the PLC data acquisition system 4 via the operating console input pipe 3.8. The pressurized pressure source system 3 is equipped with multiple oil circuit interfaces, namely oil circuit interfaces A, B, C, and D. The intelligent deployment control display 1.3 includes a power switch 1.3.1, a hybrid power supply mode indicator 1.3.2, a grid power supply mode indicator 1.3.3, a battery power supply mode indicator 1.3.4, a hybrid switch 1.3.5, a grid power switch 1.3.6, and a battery switch 1.3.7; Pay attention to check whether the "three power supply modes" on the intelligent deployment control display 1.3 are displayed correctly and whether the wiring meets the requirements. When the display light is not working, it should be red to indicate that the power is connected, and it should be green when working normally; The electric power system 2 includes an explosion-proof electrical controller 2.1 and a non-magnetic explosion-proof motor 2.2; Start each pipeline control valve on the operating console 4.1 respectively, and check the changes in the input and output pressures, as well as the stability of the replenishment pressure of the accumulator group 3.6. When the pressure is lower than the set pressure value of 19MPa, the pump group will automatically start working, and when the pressure is higher than the set pressure value of 21MPa, the pump group will automatically stop working.

[0016] In the present invention, before operation, it is necessary to check whether the external power supply interface 1.1 and the energy storage battery pack 1.2 in the electric energy storage system 1 are properly connected. Then, the power switch 1.3.1 in the intelligent deployment control operation area on the intelligent deployment control display 1.3 should be turned on. It is also necessary to check whether the hybrid power supply mode indicator 1.3.2, the grid power supply mode indicator 1.3.3 and the battery power supply mode indicator 1.3.4 are lit and red. If they are red, it means that all circuits are normally energized. At the same time, according to the needs of the site, if the grid power is normal, select the hybrid power supply mode, that is, when the hybrid switch 1.3.5 is pressed, the hybrid power supply mode indicator 1.3.2 above changes from red to green, and the hybrid power supply mode is running. At the same time, the other two power supply mode indicators: grid power supply mode indicator 1.3.3 and battery power supply mode indicator 1.3.4 are both red. In order to prevent system errors, it is necessary to check the intelligent deployment control display 1.3 again. The display mode of the screen should be: grid power → battery pack → rectifier → motor. Figure 3 The first picture in the figure; If the battery fails and needs to be repaired or replaced, we can use the grid power supply mode. That is, when the grid power switch 1.3.6 is pressed, the grid power supply mode indicator 1.3.3 above changes from red to green. At this time, the grid direct power supply mode is running, and the other two power supply mode indicators: 1.3.2 hybrid power supply mode indicator 1.3.2 and battery power supply mode indicator 1.3.4 are both red. In order to prevent the system from being misused, check the intelligent deployment control display 1.3 again. The display mode of the screen should be: grid power → rectifier → motor. Figure 3 The second picture in the middle; After selecting the power supply mode according to the on-site working environment, the power enters the rectifier 1.4 and is transmitted to the explosion-proof electrical appliance controller 2.1 in the electric power system 2 through the output circuit 1.5. The explosion-proof electrical appliance controller 2.1 and the explosion-proof pressure controller 4.8 work together to control the automatic start and shutdown of the non-magnetic explosion-proof motor 2.2. At the same time, the explosion-proof electrical appliance controller 2.1 also controls the radiator motor 3.7, the explosion-proof lamp and other electrical appliances. When non-magnetic explosion-proof motor 2.2 starts working, it drives the two sets of high-pressure gear pumps 3.1 in the pressurized pressure source system 3 to operate. The hydraulic oil is sucked from the hydraulic oil tank 3.2 through the pump oil inlet pipe 3.4 and delivered to the accumulator group 3.6 and the operating console input pipe 3.8 through the pump oil outlet pipe 3.5. The hydraulic oil then enters the operating console 4.1 through the operating console input pipe 3.8 for intelligent control. The PLC data source is obtained by transmitting system pressure data from input pressure sensor 4.3 to data acquisition display 4.2, activating the safety semi-sealed switch, safety fully sealed switch, safety slip switch, and safety ring seal switch on operation console 4.1. At this time, the pressure is output through high-pressure valve group 4.9 in a pressurized branch output. The corresponding output interfaces are A, B, C, and D, respectively, which are used to control the operation of various blowout preventers at the pressurized wellhead. The output pressure is displayed by the safety semi-sealed output pressure sensor 4.4, safety fully sealed output pressure sensor 4.5, safety slip output pressure sensor 4.6, and safety ring seal output pressure sensor 4.7, which work together to transmit the output data to data acquisition display 4.2. When the pressure in the pressure source system shown in data acquisition display 4.2 on operating console 4.1 falls below the set pressure, explosion-proof pressure controller 4.8 and explosion-proof electrical appliance controller 2.1 automatically start non-magnetic explosion-proof motor 2.2, driving high-pressure gear pump 3.1 to promptly replenish pressure in the pipeline and accumulator group 3.6, ensuring operational stability and safety. After the hydraulic oil passes through various blowout preventers, it returns to the corresponding ports A, B, C, and D through the return oil pipelines and is then sent to hydraulic oil radiator 3.3 through the oil pipes for heat dissipation and cooling. After cooling, it is finally returned to hydraulic oil tank 3.2 for replenishment operation.
