The invention discloses an oil drill pipe coupling detection system, which includes a detection device, a bottom data remote transmission system and an industrial computer; the bottom data remote transmission system input terminal is connected with the detection device, and the bottom data remote transmission system output terminal is connected The machine phase is connected; the low-level data remote transmission system is burnt on the single-chip microcomputer; the industrial computer is provided with a coupling position detection module based on the LSTM neural network model; the voltage signal output by the detection device is on the low-level data long-distance transmission system After conversion and processing, the underlying data remote transmission system sends the processed data to the coupling position detection module to separately control the opening and closing of the upper and lower semi-sealed rams of the BOP. The invention can detect the coupling well and meet the needs of the industry. Compared with other coupling detection technologies, the coupling detection technology provides a complete detection scheme and experimental results. Will not affect the coupling detection accuracy.
Description
technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a detection system for couplings of petroleum drilling pipes. Background technique [0002] At present, blowout preventers are widely used to seal oil wells in the drilling and workover industries at home and abroad, and the blowout preventer rams must be opened and closed strictly according to the process during the lifting and lowering of the drill pipe. There is a rubber core cavity in the middle of the upper and lower half-sealed rams of the blowout preventer to allow the drill pipe to pass freely, and the coupling of the drill pipe cannot pass directly. Therefore, when the coupling needs to pass through the blowout preventer, one of the half-seals needs to be opened in advance. After the coupling passes through the half-closed ram, close the half-closed ram, and then open another half-closed ram, until the coupling completely passes through the blowout preventer, ...
