Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3 An intelligent and efficient pressurized electric energy storage device includes: an electric energy storage system 1, an electric power system 2, a pressurized pressure source system 3, and a PLC data acquisition system 4. The electric energy storage system 1 includes an external power supply interface 1.1 and an energy storage battery pack 1.2. The external power supply interface 1.1 is electrically connected to the energy storage battery pack 1.2. An intelligent allocation control display 1.3 is fixedly installed on the side wall of the energy storage battery pack 1.2. A rectifier 1.4 is fixedly installed on the intelligent allocation control display 1.3. The intelligent allocation control display 1.3, the rectifier 1.4, and the output circuit 1.5 are electrically connected. The output circuit 1.5 is fixedly installed between the electric energy storage system 1 and the electric power system 2.

[0019] When using the electric energy storage 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 safely connected. At the same time, check whether the pipeline connection and the connection of each pump and valve of the pressurized pressure source system 3 meet the relevant requirements. Check whether the pressure input and output pressure sensors of the PLC data acquisition system 4 are within the calibration validity period. If they are found to be ineffective or expired, stop using it immediately and replace it. Also check whether the connector is firm and whether the connection direction of the connector is reversed, otherwise it will not be able to display.

[0020] The PLC data acquisition system 4 includes an operation control 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-sealed output pressure sensor 4.7, an explosion-proof pressure controller 4.8, and a high-pressure valve group 4.9. The operation control console 4.1 is equipped with a safety semi-sealed switch, a safety fully sealed switch, a safety slip switch, and a safety ring-sealed switch.

[0021] Note the pressure rating of the pressurized device, select a suitable explosion-proof pressure controller 4.8 to control the working pressure of the pump set, and install and use it in accordance with the well control regulations. Adjust the minimum pressure start and maximum pressure stop, and check the sensitivity at the same time.

[0022] 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 inlet pipe 3.4, a pump outlet pipe 3.5, an accumulator group 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 through the operating console input pipe 3.8. The pressurized pressure source system 3 is equipped with multiple oil circuit interfaces, which are A, B, C, and D oil circuit interfaces.

[0023] The intelligent allocation control display 1.3 includes a power switch 1.3.1, a mixed 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 mixed switch 1.3.5, a grid power switch 1.3.6, and a battery switch 1.3.7;

[0024] Please check whether the "three power supply modes" display on the intelligent dispatch control display 1.3 is correct, whether the wiring meets the requirements, and whether the indicator light is red when not working to indicate that the power is connected and green when working normally.

[0025] The electric power system 2 includes an explosion-proof electrical controller 2.1 and a non-magnetic explosion-proof motor 2.2;

[0026] Start each pipeline control valve on the operation control console 4.1 respectively, check the changes in input and output pressure values, and check whether the supplementary pressure of the accumulator group 3.6 is stable. Check whether the pump group automatically starts working when the pressure is lower than the set pressure value of 19MPa, and whether the pump group automatically stops working when the pressure is higher than the set pressure value of 21MPa.

[0027] Before operation, 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, turn on the power switch 1.3.1 in the intelligent distribution control operation area on the intelligent distribution control display 1.3, and check whether the mixed power supply mode indicator light 1.3.2, the grid power supply mode indicator light 1.3.3, and the battery power supply mode indicator light 1.3.4 are lit and red. If they are red, it means that all the lines are normally powered.

[0028] Simultaneously, depending on the on-site needs, if the grid power is normal, the hybrid power supply mode should be selected. That is, when the hybrid switch 1.3.5 is pressed, the hybrid power supply mode indicator light 1.3.2 above will change from red to green, indicating that the hybrid power supply mode is in operation. At the same time, the indicator lights for the other two power supply modes—grid power supply mode indicator light 1.3.3 and battery power supply mode indicator light 1.3.4—will both be red. To prevent system errors, the intelligent dispatch control display 1.3 should be checked again. Its display mode should be: grid power → battery pack → rectifier → motor. Figure 3 The first illustration in the middle;

[0029] If the battery malfunctions and requires repair or replacement, we can use the grid power supply mode. When the grid power switch 1.3.6 is pressed, the grid power supply mode indicator 1.3.3 above will change from red to green, indicating that the grid direct power supply mode is running. The other two power supply mode indicators—1.3.2 (mixed power supply mode) and 1.3.4 (battery power supply mode)—will both be red. To prevent system errors, we should also check the intelligent distribution control display 1.3. Its display mode should be: Grid Power → Rectifier → Motor. Figure 3 The second illustration in the middle;

[0030] After selecting the appropriate power supply mode based on the on-site working environment, the power enters the rectifier 1.4 and is transmitted to the explosion-proof electrical controller 2.1 in the electric power system 2 via the output circuit 1.5. The explosion-proof electrical controller 2.1, together with the explosion-proof pressure controller 4.8, controls the automatic start and automatic shutdown of the non-magnetic explosion-proof motor 2.2. At the same time, the explosion-proof electrical controller 2.1 also controls the radiator motor 3.7 and explosion-proof lights and other electrical appliances.

[0031] When the non-magnetic explosion-proof motor 2.2 starts working, it will drive the two sets of high-pressure gear pumps 3.1 in the pressurized pressure source system 3 to operate. The hydraulic oil is drawn from the hydraulic oil tank 3.2 through the pump inlet pipe 3.4 and delivered to the accumulator group 3.6 and the control panel input pipe 3.8 through the pump outlet pipe 3.5. The hydraulic oil enters the control console 4.1 through the control panel input pipe 3.8 for intelligent control.

[0032] The PLC data source is through the input pressure sensor 4.3, which transmits system pressure data to the data acquisition display 4.2. Activating the safety semi-sealed switch, safety full-sealed switch, safety slip switch, and safety ring seal switch on the operation control console 4.1 causes the pressure to be output through the high-pressure valve group 4.9, with corresponding interfaces A, B, C, and D, used to control the operation of various blowout preventers at the pressurized wellhead. The output pressure display is achieved through the coordinated operation of the safety semi-sealed output pressure sensor 4.4, safety full-sealed output pressure sensor 4.5, safety slip output pressure sensor 4.6, and safety ring seal output pressure sensor 4.7, transmitting the output data to the data acquisition display 4.2.

[0033] When the pressure in the pressure source system displayed on the data acquisition display 4.2 of the control console 4.1 is lower than the set pressure, the explosion-proof pressure controller 4.8 and the explosion-proof electrical controller 2.1 automatically control the non-magnetic explosion-proof motor 2.2 to start, driving the high-pressure gear pump 3.1 to replenish the pressure to the pipeline and accumulator group 3.6 in a timely manner, ensuring the stability and safety of the operation. After the output hydraulic oil passes through various blowout preventers, it returns to the corresponding interfaces A, B, C, and D through the return oil pipeline, and then is sent to the hydraulic oil radiator 3.3 for cooling. After cooling, it finally returns to the hydraulic oil tank 3.2 for replenishment.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
