Abstract

The invention discloses an oil-gas well casing reliability evaluation device, which comprises a base, a top cover, a cross beam, a threaded plate and a sliding plate. One side surface of the sliding plate is fixedly connected with a fixed rail, the fixed rail is fixedly connected with a fixed block through a fixed groove, and the lower surface of the fixed block is fixedly connected with a main-stage telescopic rod. According to the oil-gas well casing reliability evaluation device, through the arrangement of an X-ray emitter, the oil-gas well casing reliability evaluation device has the effect of detecting whether cracks exist or not, and therefore, the leakage condition is avoided after long-time use; and a pressure claw, an air cylinder and a first-stage telescopic rod are arranged in amatching manner, so that in the using process, pressure can be applied to an oil-gas casing pipe according to the corresponding pressure value, when the pressure value reaches a certain value, the oil-gas casing pipe is determined to be qualified if the oil-gas casing pipe does not deform and is determined to be unqualified if the oil-gas casing pipe deforms, the effect of detecting the hardnessof the oil-gas casing pipe is achieved, and the purpose of safety improving is achieved.

Description

technical field [0001] The invention relates to the technical field of oil and gas casing evaluation, in particular to an oil and gas well casing reliability evaluation device. Background technique [0002] Oil casing is a steel pipe used to support the walls of oil and gas wells to ensure the normal operation of the entire oil well after the drilling process and completion. Each well uses several layers of casing according to different drilling depths and geological conditions. Cement cementing is used after the casing is lowered into the well. Unlike oil pipes and drill pipes, it cannot be reused and is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes. Tubing leakage during the production process may lead to tubing collusion and pressure fluctuations affecting the safety of the casing, and may easily cause tubing leakage and puncture of the tubing. The cost of later workover is huge and there is a major...
