摘　　要：随钻电导率测井具有诸多优点,但其仍然要受井下测量环境的影响,主要包括井眼、地层电性各向异性、围岩、泥浆侵入等,若不对这些原始数据进行必要的解释处理,就可能失去随钻测井的地层评价意义。本文重点阐述了泥浆侵入和地层各向异性对随钻电导率测井的影响,同时介绍了随钻电导率测井的主要应用。Resistivity LWD has many advantages,but it is still affected by the downhole environment,including borehole,formation electrical anisotropy,surrounding rock,mud-filtrate invasion,etc.If these raw data are not analyzed and processed,the formation evaluation of LWD will be meaningless.This paper focuses on the effects of mud-filtrate invasion and formation anisotropy on Resistivity LWD and introduces the main applications of Resistivity LWD.

关 键 词：随钻电导率测井 泥浆侵入 各向异性
