Embodiment 1
[0034] Embodiment 1, with reference to attached Figure 1-5 , the single well casing gas desulfurization pressurized storage device mentioned in the present invention, its technical solution is: include oil extraction exhaust device, chemical reaction device, natural gas drying device and multi-stage labor-saving gas compression device and compressed gas storage tank 33, The described oil extraction and exhaust device will be connected to the chemical reaction device through the gas outlet pipe after the natural gas between the casing pipe 1 and the oil pipe 2 is produced, and the chemical reaction device includes a reaction tank 15, a liquid level gauge 16, a liquid discharge Hole 17, injection hole 18, gas-collecting connecting pipe 19, chemical reaction liquid 20, the chemical reaction liquid 20 that is housed in the reaction tank 15 adopts sodium hydroxide solution, and one side of the reaction tank 15 is provided with a liquid level gauge 16, the top One side is provided ...
Embodiment 2
[0052] Embodiment 2, with reference to attached Image 6 The difference between the present invention and Embodiment 1 is: the left end face of the supercharging power cylinder 24 of the multi-stage labor-saving gas compression device is connected to the compression intake pipe 23, and the above-mentioned compression intake pipe 23 is formed by combining a dynamic sealing steel pipe and a PVC steel wire composite pipe , and the left end of the power piston 27 is connected and fixed through the dynamic sealing steel pipe, and the dynamic sealing steel pipe between the power piston 27 and the left end inner wall of the booster power cylinder 24 is provided with a plurality of air outlets, that is, the A place. Moreover, the inner wall of the left end of the power piston 27 and the left end of the supercharging power cylinder 24 is provided with a limiting block 47, and the position of the intake end of the supercharging air supply pipe 25 moves to the right.
