Yu Houquan, Qu Wanli, Huang Zailu. Using Echo Pulse Echo to Detect Casing Corrosion and Defects. Logging Technology, 1997,21 (2): 129 ~ 132 The principle of using ultrasonic pulse reflection method to measure thickness is introduced. The limitations and feasibility of using this principle to measure the corrosion and defects of oil casing are analyzed and discussed. The basic scheme of using ultrasonic to detect casing thickness and numerical simulation were carried out. Simulation results show that although there are some technical difficulties, under certain conditions, the use of ultrasonic pulse echo detection of casing corrosion and defects is feasible.
