摘　　要：电阻率成象测井是石油测井中最新一代的测井方法 ,对测井仪器响应的精确模拟 ,可以为此类仪器的优化设计和资料解释提供依据。针对电阻率成象仪激励条件比较复杂的特点 ,同时考虑井下地层固有的非均质性 ,选用有限元方法对仪器产生的位场进行分析 ,并对一些典型的地层模型进行模拟 ,给出其电阻率井壁成象结果 。Resistivity imaging is the newest method of well logging. The precise simulation of imager is the basis of optimum design of tools and interpretation of well log. In view of the complex sources of resistivity imager and the inhomogeneity of underground formations, the finite element method is applied to analyze the potential fields excited by imager. Some typical formation models are numerical simulated, and the results are converted to resistivity imaging to reflect the formation characteristics on the wall directly.
