Abstract

The invention discloses casing pipe detection equipment based on image recognition. The casing pipe detection equipment comprises a box body, a groove formed in the side face of the box body, a flat plate in sliding fit with the inner wall of the groove and a positioning plate fixedly connected with the inner wall of the groove. The device further comprises a touch sensing device and an elastic buffering piece. The first annular groove is formed in the wall of the groove, an annular track is arranged in the first annular groove, the image acquisition device is in sliding fit with the annular track, and the first driving device is used for driving the image acquisition device to move circumferentially along the annular track; the image acquisition device is used for providing an image source for the image recognition system. The automatic detection device is used for solving the problems that in the casing production process in the prior art, the automation degree of male buckle end detection is low, the labor intensity is large, and missing detection and false detection are prone to occurring, and the purposes of improving the automation degree of casing detection and reducing influences on field casing operation and well logging operation are achieved.

Description

technical field [0001] The invention relates to the field of oil and gas exploitation, in particular to casing detection equipment based on image recognition. Background technique [0002] Casing is a pipe used to support the well wall of an oil and gas well to ensure the normal operation of the entire oil well during the drilling process and after completion. It is the main component that isolates the wellbore and the well wall, and is important to ensure subsequent well completion and oil production. composition. According to the provisions of "Processing, Measurement and Inspection of Tubing, Casing and Line Pipe Threads", for casing joints with partial trapezoidal threads and low-grade large-size round threads, the triangle mark should be printed at a certain distance from the pin end. , as the control position for the buckle-up of the casing, so that the collar of the casing can be buckled up to a reasonable position to ensure the effectiveness of the sealing between t...
