摘要
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.
