摘　　要：对钻具输送的无电缆测井方式的作业特点和使用的深度信息获取方法进行分析,指出因作业方式的变化,目前深度信息获取方法遇到的问题。提出了采用实时存储大钩运动和大钩负荷信息,事后结合钻具长度和测井数据的波动性,进行深度信息校正的方法,并编制了相应的软件。现场应用表明该方法提高了获取深度信息的质量,能够满足现场作业要求。In this paper, the characteristics and the existing problems of the depth information acquisition method of the no-cable logging are analyzed. According to the operating characteristics of the no-cable logging, the motion information of the hook and hook load information are combined with the length of the drilling tools and the fluctuation of the logging data to correct the depth information, and the correspond-ing software is compiled. Field application shows that this method can improve the quality of depth information, and can meet the require-ments of operation.
