The invention discloses a non-metallic lined gas storage well for storing natural gas or hydrogen-mixed natural gas and an installation method thereof. The non-metallic lined gas storage well comprises a cylinder body, an outer connecting pipe, a reinforcing rib, a pressure plate layer, a cementing layer and a fastener There is a tubular cavity in the middle of the cylinder body, the upper part is provided with a connecting part, and the lower part is provided with a lower head; the cylinder body is buried in the ground, and the outer side of the cylinder body is sleeved with a reinforcing rib, and the outer side of the cylinder body and the reinforcing rib is provided with a cementing layer; The upper part of the cementing layer is provided with a pressure plate layer, and the pressure plate layer is fixed to the cementing layer by fasteners; the outer pipe is provided with a drainage pipe, an air intake pipe and an exhaust pipe, and the outer pipe is connected with the pipe connection part of the cylinder body, and the cylinder body is at least partially composed of Made of non-metallic materials. This can not only ensure the compressive strength, but also bring about the use of non-metallic materials to ensure corrosion resistance, hydrogen embrittlement resistance, and low cost, thereby optimizing the design of underground gas storage wells for storing natural gas and hydrogen-mixed natural gas. |
