Abstract

The invention provides an oil pipe detection rod. The oil pipe detection rod comprises a rod body, and a plurality of mounting grooves are formed in the circumferential side wall of the rod body; a plurality of sensors are provided, the plurality of sensors are in one-to-one correspondence with the plurality of mounting grooves, and the sensors are embedded in the mounting grooves; and the signal processing circuit board is arranged in the rod body. The problem that in the prior art, oil pipe detection is difficult is solved.

Description

technical field [0001] The invention relates to the technical field of oil and natural gas logging, in particular to an oil pipe detection rod. Background technique [0002] As the channel for oil and gas collection, storage and transportation at the bottom of the well, the oil pipe plays an important role in the oil production operation. Because the oil pipe has been in a complex and harsh downhole environment for a long time, and the main structure of the oil pipe is a steel alloy structure, the oil pipe will inevitably suffer Stress mechanical damage, corrosion damage and other damage, the common manifestations of tubing damage mainly include tubing corrosion, deformation, perforation, rupture, fracture and so on. Tubing damage seriously threatens the safe production of oil and gas wells, and even leads to catastrophic accidents such as blowouts and platform overturning. Therefore, it is necessary to detect the leakage of oil and gas well casings in time to prevent secon...
