Description

Technical Field

[0001] The utility model relates to the technical field of early warning detection equipment, in particular to an early warning detection equipment for oil drilling. Background Art

[0002] Oil drilling is the process of discovering oil-bearing blocks through exploration. It refers to the use of special equipment and technology to drill a cylindrical hole of a certain diameter downward or to one side at a pre-selected surface location and reach the underground oil and gas layer. With the in-depth development of oil drilling projects, the research and application of accident warning technology has become particularly important. Accident warning technology can help companies perceive potential dangers in a timely manner, reduce the possibility of accidents, and ensure project safety and the safety of life and property of personnel. At present, oil drilling project accident warning technology mainly includes various technical means such as acoustic warning, liquid level monitoring, seismic monitoring, and gas detection.

[0003] At present, when conducting liquid level warning detection in oil drilling projects, wireless immersion level meters are usually used to detect the liquid levels of storage tanks and pipelines, and the liquid level changes are uploaded to the oil drilling early warning detection platform system for recording through 4G / NB-loT signal transmission. When installing this immersion level meter, a steel pipe with an inner diameter of about 45mm is generally fixed in the oil drilling fluid pipe, and several small holes are punched at different heights in the steel pipe. Then the immersion level meter is placed in the steel pipe. This installation method of the immersion level meter requires the steel pipe and the meter head of the immersion level meter to be installed separately, which increases the cumbersomeness of the disassembly and maintenance of the immersion level meter, affecting the maintenance time of the immersion level meter when used as an oil drilling early warning detection equipment. For this reason, we propose an oil drilling early warning detection equipment. Utility Model Content
