A fixing ring is fixedly connected to the outer surface of the shielding shell, and a threaded fixing hole is opened through the top of the fixing ring. Output pipes are connected through both sides of the shielding shell, and an electric throttle valve is connected through the top of the output pipe.
[0005] Preferably, an electric telescopic rod is fixedly connected to the top of the fixed plate, and a transmission arm is fixedly connected to the top of the electric telescopic rod.
[0006] Preferably, a wrapping shell is fixedly connected to the tail end of the transmission arm, and a telescopic shell is fitted inside the wrapping shell. Limiting holes are opened through the front of both the wrapping shell and the telescopic shell, and six limiting holes are provided.

The telescopic shell moves inside the wrapping shell under the action of external force, which drives the transmission plug to move up and down. Then, the external bolt is inserted into the limiting hole to fix the telescopic shell after the length adjustment, thereby increasing the transmission range of the pressurized operation device and improving the extraction effect of oil and gas wells.

Detailed Implementation
[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0021] Reference Figures 1-4A pressurized oil and gas well operation device includes a fixed plate 1 and a delivery pipe 2. The delivery pipe 2 is connected through the top of the fixed plate 1. The fixed plate 1 provides fixing points for the delivery pipe 2, an electric telescopic rod 7, and a support rod 17, which are fixedly connected to its top and bottom. The delivery pipe 2 is connected through the top of the fixed plate 1, providing space for the user to move the transmission rod 8 up and down. A shielding shell 3 is connected through the bottom of the delivery pipe 2. The shielding shell 3 is connected through the bottom of the delivery pipe 2, providing fixing points for a fixing ring 4 and an output pipe 5, which are fixedly connected to its outer surface. It is connected to the top of an external oil and gas well to facilitate the subsequent output of oil and gas. A fixing ring 4 is fixedly connected to the outer surface of the shielding shell 3. The fixing ring 4 is fixedly connected to the shielding shell 3. When it is necessary to fix the shielding shell 3, external bolts can be inserted into the fixing ring 4 by external force, and then inserted into the oil and gas well to complete the initial fixation of the shielding shell 3. The top of the fixing ring 4 is provided with a threaded fixing hole. Both sides of the shielding shell 3 are connected to the output pipes 5. When the output pipes 5 are connected, oil or natural gas is output to the external environment under the action of gravity, thereby completing the output of oil and gas. The top of the output pipes 5 is connected to the electric throttle valve 6. When it is necessary to output oil and gas, electrical energy can be transmitted to the electric throttle valve 6 through the external control component. At this time, the electric throttle valve... 6. Open the internal connection of the drive output pipe 5. An electric telescopic rod 7 is fixedly connected to the top of the fixed plate 1. When it is necessary to extract oil and gas from inside the oil and gas well, electrical energy can be transmitted to the inside of the electric telescopic rod 7 through an external control component. At this time, the electric telescopic rod 7 extends or retracts, driving the transmission rod 14 indirectly connected to its output end to move up and down. A transmission arm 8 is fixedly connected to the top of the electric telescopic rod 7. The transmission arm 8 moves up and down under the drive of the electric telescopic rod 7, driving the transmission rod 14 indirectly connected to its bottom to move up and down. The transmission rod 14 is fixedly connected to the bottom of the two extension plates 13. The transmission rod 14 moves up and down under the drive of the transmission arm 8, driving the transmission plug 15 fixedly connected to its bottom to move up and down. The transmission rod 14 is fixedly connected to the bottom of the transmission plug 15. The transmission plug 15 moves up and down under the drive of the transmission rod 14. Under the action of negative pressure, it generates suction force on the oil and natural gas inside the oil well, and transports the oil and natural gas to the inside of the shield shell 3. The bottom of the fixed plate 1 is fixedly connected to the support rod 17. The support rod 17 is fixedly connected to the bottom of the fixed plate 1, and provides a fixing point for the flange 18 fixedly connected to its bottom. There are four support rods 17. The bottom of the fixed plate 1 is fixedly connected to the flange 18. When it is necessary to fix the whole device, the external bolts can be inserted into the inside of the flange 18 by external force and then inserted into the inside of the external fixing plane to complete the fixing of the whole device.
[0022] Reference Figure 1 , Figure 2 and Figure 5A housing 9 is fixedly connected to the tail end of the transmission arm 8. The housing 9 provides a connection point for the telescopic housing 10, which is fitted inside the transmission arm 8, and also provides a fixing point for the limiting hole 11 that penetrates through its outer surface. The telescopic housing 10 is fitted inside the housing 9. When it is necessary to adjust the pressure range of the transmission plug 15, the telescopic housing 10 can be pulled by external force to adjust the telescopic length of the telescopic housing 10 and adjust the transmission range of the transmission plug 15. Limiting holes 11 are opened through the front of both the housing 9 and the telescopic housing 10. After the range of motion is adjusted, the external bolts are inserted into the limiting holes 11 to fix the telescopic shell 10 after the length adjustment, and then the transmission length is adjusted. There are six limiting holes 11. The bottom of the telescopic shell 10 is fixedly connected to the wrapping frame 12. The wrapping frame 12 provides a connection point for the extension piece 13 that is bolted to its inner side. The extension piece 13 is bolted to the inner side of the wrapping frame 12. The extension piece 13 is bolted to the wrapping frame 12 to fix the wrapping frame 12 and the extension piece 13, and then the transmission rod 14 is fixed.
[0023] Reference Figure 1 An active electrode 16 is fixedly connected to the top of the fixed plate 1. When the moisture in the external environment is conducted to the outer surface of the active electrode 16, the active electrode 16 is made of a material with a high metal activity series. It preferentially undergoes an oxidation reaction to transport some electrons to the outer surface of the device, thus slowing down the corrosion rate of the device. There are two active electrodes 16, and the active electrodes 16 are located outside the conveying pipe 2.
[0024] In use, this invention first inserts the external bolts into the interior of the external fixing plane by external force to fix the entire device. Then, the external bolts are inserted into the interior of the fixing ring 4 by external force and into the interior of the oil and gas well to fix the shielding shell 3. When oil and gas need to be extracted, electrical energy can be transmitted to the interior of the electric telescopic rod 7 via the external control component. At this time, the electric telescopic rod 7 extends or retracts, driving the transmission rod 14 indirectly connected to its output end to move up and down. The transmission rod 14 moves up and down under the drive of the transmission arm 8, driving the transmission plug 15 fixedly connected to its bottom to move up and down. The transmission plug 15 moves up and down under the drive of the transmission rod 14, generating suction force on the oil and natural gas inside the oil well under negative pressure, and transporting the oil and natural gas to the inside of the shielding shell 3. Then, electrical energy is transmitted to the interior of the electric throttle valve 6 via the external control component. At this time, the electric throttle valve 6 opens to drive the internal connection of the output pipe 5. When the internal connection of the output pipe 5 is made, the oil or natural gas is output to the external environment under the action of gravity, thereby completing the output of oil and gas.
