Problems solved by technology

In the past, pipe coupling detection devices were generally not used in oil and water wells under pressure. The main reason is that the existing detection devices or instruments are all non-contact induction. It needs to be debugged for a long time, and the signal detected by this device needs to be judged and identified by personnel with a certain technical level, and the false alarm rate is high, so it is difficult to popularize and apply
In recent years, an inductive snubbing detection device for pipe strings under pressure needs to be equipped with certain post-processing equipment to work normally, and the technical requirements and cost of the application in the snubbing operation site of oil and water wells are relatively high and reliable. Low performance, can not meet the actual needs of field applications

Description

Technical field: [0001] The invention relates to a wellhead device used for workover operations of oil and water wells in oil fields. Background technique: [0002] During the workover operation of oil and water wells under pressure, when the coupling of the pipe string is close to the position of the BOP of the wellhead ram, it is necessary to send an alarm or control signal from the coupling detection device to make the BOP of the wellhead ram open quickly and timely to ensure The pipe string coupling passed the wellhead ram blowout preventer smoothly. In the past, pipe coupling detection devices were generally not used in oil and water wells under pressure. The main reason is that the existing detection devices or instruments are all non-contact induction. It needs to be debugged for a long time, and the signal detected by this device needs to be judged and identified by personnel with a certain technical level, and the false alarm rate is high, so it is difficult to pop...
