MIT和MID-K组合测井技术在川渝地区的应用

川渝地区高温高压高危井多,井下状况复杂,井筒完整性测井评价在油气田开发中有着重要意义。分析讨论了多臂井径MIT和电磁探伤MID-K测井技术的特点和不足,将2种测井技术组合应用可满足该地区复杂井况油套管损伤检测的需求。设计制作了管柱损伤检测实验装置,验证多臂井径MIT和电磁探伤MID-K组合测井技术的可行性。通过对川渝地区280余口井测量结果跟踪分析,建立了适合该地区油套管损伤程度评价的5级测井评价标准;通过21口井起油管实际验证测井评价结果显示,符合率为90.48%。

Application of MIT and MID-K Combination Logging Technology in Sichuan and Chongqing Area

There are many high temperature ,high pressure and high‐sulfur wells with downhole complex condition in Sichuan and Chongqing region .Wellbore integrity logging evaluation is of great significance in the development of oil and gas fields .Discussed are the characteristics and shortages of the MIT and MID‐K logging technologies ,and combination of MIT and MID‐K logging technology is used to meet the needs of the complex well tubing and casing damage detection in this area . Design and manufacture of pipe string damage detection experimental device verified the feasibility of MIT and MID‐K combination logging technology . Through tracking analysis more than 280 wells measurement results in Sichuan and Chongqing region , established is the oil tubing and casing damage degree log evaluation standard with 5 level for the area .The testing results show that the coincidence rate of 21 wells log evaluation is 90.48% .
