阵列感应测井(MIT)是一种能够同时获得多种纵向分辨率、多种径向探测深度的感应型电阻率测井方法。本文主要介绍了阵列感应测井仪(MIT)的基本原理,结合阵列感应测井(MIT)在长庆油田的应用实例,具体分析了MIT曲线在均质地层的响应关系及标准曲线要求;然后从仪器刻度、螺杆钻具、仪器是否居中、仪器预热温度、井眼规则程度5个方面对阵列感应测井进行了影响因素分析,最后总结了阵列感应测井的曲线质量控制要求。
Array Inductive Logging (MIT) is an inductive resistivity logging method that enables the simultaneous acquisition of multiple vertical resolutions and multiple radial probing depths. This paper mainly introduces the basic principle of array induction logging tool (MIT). Combining with the application example of array induction logging (MIT) in Changqing Oilfield, the response relationship of MIT curve in homogeneous formation and the requirements of standard curve are analyzed. Then, The influencing factors of array induction logging are analyzed from five aspects: instrument scale, screw drill, centering of instrument, preheating temperature of instrument and rule degree of wellbore. Finally, the requirement of curve quality control of array induction logging is summarized.
