摘　　要：微电极测井曲线的纵向分辨能力强，划分薄互层和薄夹层比较可靠，是砂泥岩剖面组合测井中不可缺少的测井方法。但微电位和微梯度测井曲线受外围影响因素较多，测井资料在地质解释上存在不少争议。该文章对国内各大油田微电极测井曲线存在问题进行总结和分析，提出测井曲线质量控制措施，提高微电极测井曲线质量。MicroloG logging has high longitudinal resolution and reliable division of thin interheddings and interlinings.It is a indispensable in sand mudstone profile combination logging.But micro-normal and micro-inverse logging curves are affected lot by peripheral influencing factors. There are many disputes about the well logging data in geological interpretation.This paper summarized and analyzed the problems existing in miorolog curves in each inland giant oilfield.It put forward some counter measures of quality control to improve microlog curves.
