Embodiment Construction
[0044] The leak detection tool used in the high-pressure gas leak detection method provided by the present invention includes a sealing tool and a detection gas collection sleeve. The two sides of the connecting screw buckle part that may leak are used to establish an inner airtight space that can be filled with detection gas, or an air-filled space; the detection gas collection sleeve is arranged outside the tubing string or casing string or auxiliary tools, Connect the thread buckle part that may leak, and cover the part to be leaked in the detection gas collection sleeve to establish an external closed space or detection space that can detect leakage; the inflatable space is provided with a high-pressure detection gas inlet, used It is connected with a device that generates high-pressure detection gas; the high-pressure detection gas enters the gas-filled space; and a gas detection instrument is connected to the detection space.
[0045] The device that can quickly generate...
