摘　　要：针对以往工程录井参数大多用于钻头磨损状况、钻具刺漏等方面的判别,应用程度相对较低的问题,该文提出了将录井参数用于管柱摩阻、摩扭分析中,通过GS69-1井的试验,获得了较好的效果,证实利用录井参数检测管柱摩阻、摩扭,对保障大位移定向井的施工安全及井身结构优化设计提供了有利的指导和保障。The paper puts forward the logging parameters to be used in the pipe string frictional resistance and wrench movement analysis of pipe string according to the former problem that engineering logging parameters are mostly used to discriminate bit wearing degree and drill string piercement.The method has been proven to be better through the experiment of GS 69-1 well. It is verified that using logging parameters to test pipe string frictional resistance and wrench movement provides beneficial guiding and guarantee to secure drilling safely in large displacement directional well and designing wellbore structure optimally.
