摘要
Abstract
As a result of complex LWD induction resistivity tool structure,measuring signal is effected by magnetic core,reflective layer and drill collar; and due to the tool's asymmetric structure,the conventional middle induction resistivity logging theory can not meet the requirements of the tool research and design.The structure and performance of LWD induction resistivity tool are introduced.With the help of numerical simulation software “Maxwell” based on the finite element method,the effects of magnetic core,reflective layer and drill collar on the measurement signal are calculated and analyzed,and the K value of tool is determined too.The actual measured value and the numerical value are compared.The research provides a theoretical basis for the tool data processing and future development.关键词
