摘　　要：录井过程中井深是一个最重要的参数,该参数测量正确与否是录井成败的关键。陆上和海上的录井方法虽然大部分都是相同的,但是有一部分参数的测量由于所处环境不同而采用的方法有一定的差异,其中井深参数测量海上和陆地就有所区别。在对海上浮动钻井平台上经常使用的3种测量井深的方法——绞车与游车补偿传感器测量法、大钩位置与升沉补偿传感器测量法和压力水瓶传感器测量法分别介绍的基础上,通过各种测量方法的相互对比,从中确定一个相对较好的测量方法。Well depth is the most important parameter during mud logging,which determines the success or failure of mud logging operation.Though the most parts of mud log- ging methods onshore or offshore are same,the measure- ments adopted for a part of parameters exist differences due to the different environments,among which,the measure- ment for well depth parameter offshore is different from that of onshore.On the basis of the detailed introduction of 3 common well depth measuring methods on offshore drill- ing platform,which are the methods of drawworks and traveling block compensation sensor,hook position and heave compensation sensor and pressure water bottle sen- sor,the paper put forward a relative good measuring meth- od through the comparison between them.
