At present, when the built-in detection tool is used for detection, when the detection tool is unsealed, the high-pressure gas in the annular space formed by the detection tool and the inner wall of the oil casing will be released quickly in a short period of time, resulting in a large force that reacts on the On the detection tools, especially when used to detect the sealing performance of small-sized tubing and casing pipe strings, the built-in detection tools are small in size and light in weight, which may easily cause the high-pressure gas to rush out of the tubing and casing, bringing safety hazards to the drilling platform

The invention discloses oil and gas well pipe string thread sealing property detection equipment and method, and belongs to the technical field of oil and natural gas drilling and production technologies. The oil and gas well pipe string thread sealing property detection equipment comprises a barrel-shaped shell, a gas detection passage is arranged in the wall of the shell, an external air source connecting hole which is communicated with the gas detection passage is formed in the middle of the shell, openings of the gas detection passage in the inner walls of the two ends of the shell are equipped with piston cylinders which can slide relatively, the inner walls of the two ends of the shell are equipped with compressed closed mechanisms respectively, the piston cylinders are matched with the compressed closed mechanisms, sliding of the piston cylinders can make the compressed closed mechanisms attached to the outer wall of an oil casing, and annulus sealing is achieved. According to the oil and gas well pipe string thread sealing property detection equipment and method, detection is conducted specially for small-sized oil casing pipe string sealing property, larger reactive force produced through gas used for detection on the detection equipment after the detection is completed can be effectively avoided, and potential safety hazards caused to a drilling platform due to the fact that the detection equipment is prevented from being pushed out of the oil casing through high pressure gas are avoided.
Description
technical field [0001] The invention relates to the technical field of oil and natural gas drilling, in particular to a detection technology for oil and gas well pipe strings. Background technique [0002] In the process of oil and gas exploitation, it is often necessary to test the tightness of oil and gas well pipes at joints. At present, when the built-in detection tool is used for detection, when the detection tool is unsealed, the high-pressure gas in the annular space formed by the detection tool and the inner wall of the oil casing will be released quickly in a short period of time, resulting in a large force that reacts on the For testing tools, especially when used to test the sealing performance of small-sized tubing and casing strings, the built-in testing tools are small in size and light in weight, which can easily cause the high-pressure gas to rush out of the tubing and casing, bringing safety hazards to the drilling platform.
