摘  要:井下油套管损伤(包括电化学腐蚀及机械损伤)是油气勘探、开发中最为普遍的现象,给经济造成巨大损失、给油气生产和环境保护带来极大困难。MID-S多层管柱扫描式电磁探伤成像测井仪,增加了井周扫描功能,在测量精度上有了较大的提高。通过对各种电磁探伤异常曲线进行分析以及对造成曲线异常的原因进行了总结,提高了测井资料的解释符合率,能够为油田套损监测和措施作业提供更为准确、详实的依据。Downhole casing damage(including electrochemical corrosion and mechanical damage) is the most common phenomenon in oil and gas exploration and development, which causes huge economic losses and brings great difficulties to oil and gas production and environmental protection. MID-S multi-layer string scanning electromagnetic flaw detection imaging logging tool has increased the function of borehole scanning, and has greatly improved the measurement accuracy. Through the analysis of various abnormal curves of electromagnetic flaw detection and the causes of abnormal curves, the interpretation coincidence rate of logging data can be improved, to provide more accurate and detailed basis for casing damage monitoring and measure operation.
