Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of layered injection and production, specifically to a layered injection and production linkage alarm device. BACKGROUND

[0002] Layered injection and production technology is suitable for the exploitation of multi-layer gas wells, especially when there are large differences in the geological characteristics and exploitation conditions of each layer of gas reservoir, layered injection and production technology can play a greater advantage. With the continuous development of oil and gas exploitation technology, layered injection and production technology is also constantly innovating and improving. In the future, layered injection and production technology will pay more attention to the development of intelligence, automation and refinement to improve the efficiency and benefit of exploitation, and reduce the cost and environmental impact of exploitation.

[0003] During the layered injection and production process, gas leakage may occur, so we need to use a gas leakage alarm device. Because the layered injection and production uses high-strength special-purpose pipelines, leakage usually occurs at the pipeline connection. The existing technology sets an electromagnetic valve at the outlet end of the pipeline connection and a gas leakage cavity at the pipeline connection to detect whether the pipeline leaks. When using the electromagnetic valve at the outlet end of the pipeline connection, if leakage occurs at the pipeline connection, the electromagnetic valve cannot cut off the gas at the inlet end. Even if the pipeline connection detects gas leakage and sends an alarm, the gas is still in a continuous leakage process, and there is still a certain potential danger if the staff cannot handle it in time.
