Abstract

The invention discloses casing vibration shaft mouth monitoring detection equipment. The casing vibration shaft mouth monitoring detection equipment is characterized in that one end of a metal probe is magnetically attached to a micro-vibration sensor, and the other end of the metal probe is magnetically attached to a piezoelectric type acceleration sensor by a micro-vibration signal input port of a detector, and is in a data connection with a dynamic data acquisition device by a charger amplifier; the dynamic data acquisition device is used to input data in a computer terminal by a communication port, and the data is analyzed by matched software; after integrating processing of acquired acceleration signals is carried out twice, the acceleration signals are converted into amplitude signals; the amplitude signals are used to generate a sound real-time oscillogram; sound signals are played back in a sound box by an audio output port; Fourier operation of time domain signals is used to generate frequency domain signals to generate a spectrogram; by comparing the frequency domain signals with known object frequency domain information, a collided object type is identified.

Description

technical field [0001] The invention relates to the field of petroleum technology, in particular to casing vibration wellhead monitoring and detection equipment. Background technique [0002] Casing damage can result in overall pressure loss, thinning of production tubing, or the inability to run intervention tools. In actual operation, the one-time success rate of the fishing operation with the wrong casing is not high. The reason is that apart from complex well conditions and improper selection of fishing tools, one of the main reasons is that fishing is blind and it is difficult to achieve accurate fishing. In this case, the correctness of catching the falling objects in the well is particularly important. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problem of low first-time success rate in salvage construction, and provide a casing vibration wellhead monitoring and detection device. [0004] The invention ...
