Self-offset well shock detection device

Abstract

The invention discloses a self-offset well shock detection device, and relates to a well shock detection device. A motor is arranged in a shell; the output shaft of the motor is provided with a lead screw connected with a sliding nut; the sliding nut is hinged with a support rod; one end of the lead screw connected with the output shaft of the motor is provided with a flat-hole connector, and theoutput shaft of the motor is a flat shaft correspondingly; the flat-hole connector on the lead screw is in sliding connection with the output shaft of the motor; a compression spring is arranged between the flat-hole connector on the lead screw and the sliding nut; and after the support rod is unfolded, if conditions that soil on the well wall is loose and collapsed, a position is moved and a support point slides occur, the elasticity of the compression spring can push the sliding nut to drive the support rod to reliably support the well wall, so that the automatic support and offset can be achieved. The shock detection device is reliable to couple the well wall, low in noise, and high in precision, accurately receives signals, acquires signals truly and reliably, accurately performs analysis and judgment, and is suitable for well shock detection.

Description

technical field [0001] The invention relates to a vibration detection device in a well, in particular to a self-compensating vibration detection device in a well. Background technique [0002] We know that the vibration detection device in the existing well is to be provided with a motor in the housing, and the output shaft of the motor is provided with a screw mandrel, the screw mandrel is connected with the sliding nut, and the sliding nut is hinged to the strut. This kind of vibration detection device in the well, because the output shaft of the motor is provided with a screw rod, the screw rod is connected with the sliding nut, the sliding nut is hinged to the support rod, and the support rod is opened to support the well wall. Movement, support point sliding, and no support compensation function, resulting in unreliable coupling between the vibration detection device in the well and the well wall, high noise, inaccurate received signals, poor precision, unreal and unrel...

AI Technical Summary

Problems solved by technology

[0003] The technical problem solved by the present invention is to solve the problem of unreliable coupling between the vibration detection device in the well and the well wall when the support rod is opened to support the well wall. Large noise, inaccurate received signals, poor precision, untrue and unreliable collected signals, and inaccurate analysis and judgment. Provide a support rod to support the well wall. Point sliding, with support compensation function, reliable coupling between the well vibration detection device and the well wall, low noise, accurate signal reception, high precision, true and reliable signal acquisition, and accurate analysis and judgment.
