摘　　要：在油田测井作业中,深度是测井信息重要的有机组成部分,所有地层或套管的测井参数资料都与深度相对应,离开了深度的测井信息将失去任何物理和地质意义,因此,正确的测井深度直接关系到对地质层位的划分、油气层的判断,测井作业中深度的准确性是合格测井资料的最基本要素,本文从测井深度采集系统原理入手,对深度测量装置,深度采集处理和电缆深度以及深度误差产生的原因进行研究,确保测井系统在不同区域测井的深度准确性。深度校正的方法主要有套管鞋校深和伽玛校深方法。During logging operations in the oil field,the depth is an important organic component of the logging information and the logging parameters correspond to the depth,inaccurate depth will make the logging information lose any physical and geological significance,therefore,the correct logging depth is directly related to the division of geological horizon and the hydrocarbon reservoir.the accuracy of depth in logging operations is the most basic element of qualified logging data.This paper starts with the principle of logging depth acquisition system,and studies the causes of depth measuring device,depth acquisition processing and cable depth and depth error,so as to ensure the depth accuracy of logging systems in different areas.Depth correction mainly includes casing depth and gamma depth correction.
