Summary As oil and gas exploration progresses into deeper ultradeep territories, the radio frequency identification (RFID) tags used in drillpipes are required to demonstrate enhanced resilience elevated temperatures pressures. Current research on for ultrahigh temperature pressure environments is relatively scarce. This study focuses application of RFID drilling operations, aiming further enhance tags’ resistance meet requirements. Numerical simulations were conducted assess mechanical properties installed varying dimensions under conditions process enabled optimization installation holes. The optimal tag determined be φ24.3×7 mm, with corresponding hole being φ24.3×11 mm. To evaluate high-temperature endurance tags, they subjected a 200℃ period time, after which maximum 230℃ was applied. Furthermore, bespoke high-pressure apparatus conduct 7-day test at 200 MPa. findings demonstrated that exhibited reliable performance even when an extreme 230℃. consistent prolonged periods high pressure. efficacy validated through 11-well field experiment, wherein embedded no indications detachment or deterioration. Once removed from apparatus, able read automatically real thus enabling automated collection data drillpipe actual operating conditions. this provide valuable insights establish foundation design challenging deep exploration.

Abstract With the popularization and application of production enhancement measures such as nitrogen gas injection lift drainage in oil wells western China, corrosion failures wellhead devices, downhole tubing strings tools occur frequently. Oxygen ingress has become one main causative factors inducing failure metallic materials. In this work, behavior a variety materials O2-CO2 coexistence environment was investigated. Based on experimental results general corrosion, maximum pitting rate, morphology composition products, characteristics possible mechanisms were discussed. The showed that presence oxygen significantly enhanced low alloy steels (P110 3Cr) stainless (13Cr 316), especially promoted localized 13Cr steel. critical content suitability several for use oxygen-containing environments comprehensive consideration material upgrading, control inhibitors, it concluded combined steel inhibitors may be relatively more practical economical solution.
