Abstract

The invention relates to an environment-friendly drilling/workover operation oil pipe flaw detection device which comprises a flaw detection ball box and a flaw detection platform, a plurality of flaw detection balls are arranged in the flaw detection ball box, an outlet is formed in the bottom of the flaw detection ball box, a switch for controlling the flaw detection balls to fall out is arranged at the outlet, and the flaw detection ball box is arranged above the front of the flaw detection platform. A lifting platform is arranged below the outlet, a pushing device is arranged on one side of the lifting platform, and the pushing device is connected with a power conveying device and a pressure intensity detection device. The device is used for detecting flaws in the oil pipe in the field of lifting and lowering the oil pipe during well repair, and has the advantages of improved efficiency, convenience, environmental protection and no influence on the efficiency of well repair operation.

Description

technical field [0001] The invention relates to a mechanized workover operation device in the petroleum industry, in particular to an environment-friendly oil pipe flaw detection and detection device for drilling / workover operation. Background technique [0002] During the oil production process of oil wells, the sucking pipes installed in the formation will be damaged or damaged due to eccentric wear or corrosion. The oil sucking pipes need to be cleaned and damaged. If the tubing damage is not detected in time and corresponding measures are taken, it will have a serious impact on the normal production of the oil well. [0003] At present, the detection methods of oil pipe damage are mostly divided into three types: [0004] 1) After the oil well operation is taken out of the formation, the oil pipe is transported to the maintenance workshop. The oil pipe is cleaned in the maintenance workshop, and the oil pipe is placed horizontally and passed through the flaw detection p...
