摘要
在水平井测井中，由于地层界面与井轴接近平行，因此测井仪器响应随地层电导率的变化规律与垂直井有着本质差别。基于三维数值模式匹配法，模拟了水平井中不平整界面地层双感应测井的响应特征；通过数值分析，研究了水平井中不平整界面地层的阶梯高度和阶梯长度对双感应测井响应的影响，为水平井测井解释工作中消除复杂地层界面对感应测井的影响提供了理论参考。
Abstract
In horizontal well,the formation boundary is almost parallel with well axis,so the response of logging equipments varying with formation conductivity is quite different from that in vertical well.Based on the 3D Numerical Mode-Matching(NMM)method,we simulated the response of dual induction log of the formation with uneven boundary in horizontal well,and the impact of step height and step length was studied.The research result provided theoretical reference for removing the impact of complex formation interface on induction logging.
