The invention provides a coupling detection device. The coupling detection device comprises a coupling detection device body, a detection part and a warning device. The warning device is electrically connected with the detection part. An upper flange is arranged at the upper end of the coupling detection device body. A lower flange is arranged at the lower end of the coupling detection device body. The detection part is an acoustic detection part and comprises an upper acoustic wave emitter, a lower acoustic wave emitter, an acoustic wave receiving device and a data processor. The upper acoustic wave emitter and the lower acoustic wave emitter are located on the same side of the coupling detection device body. The acoustic wave receiving device is located on the other side of the coupling detection device body. The central axis of the acoustic wave receiving device is located in the position between the upper acoustic wave emitter and the lower acoustic wave emitter. The upper acoustic wave emitter, the lower acoustic wave emitter and the acoustic wave receiving device are fixedly connected with the coupling detection device body. The data processor is electrically connected with the acoustic wave receiving device. The warning device is provided with a Bluetooth alarm. According to the coupling detection device, coupling detection is high in accuracy rate and small in error.
Description
Technical field [0001] The invention relates to the technical field of oilfield production logging tool design, in particular to a coupling detection device. Background technique [0002] Work under pressure is often used in the process of erection and maintenance of oil wells. Pressure work refers to a special operation method in which high-pressure oil and water wells are used to raise and lower oil pipes without killing the well or blowing out. The main device for working under pressure is the annular blowout preventer or the ram blowout preventer. The sealing rubber ring deforms under the control of hydraulic pressure to hold the tubing in the well tightly and realize the sealing of the wellhead. Under normal circumstances, when the well pressure exceeds 14MPa, the annular blowout preventer works alone, which is not enough to ensure safety. At this time, a single ram blowout preventer is required to work with it to meet the requirements for well closure. When the single ram ...
