超深井测井深度质量控制方法探讨

摘要

The true depth is the basis of applying logging data.In Tahe oilfield,the logging depth of ultradeep well is calibrated by the standard well logging and its correction amount is calculated by the mathematical fitting way.Then analysis focuses on the differences between calibration environment of standard wells and actual logging environment,followed by some suggestions of corresponding controlling measures.Meanwhile,discussions are carried out about error causes of engineering depth,depth of well log and logging depth,and the detection method of on-site logging depth.%准确的深度是测井资料应用的基础,塔河油田超深井测井深度采用测井标准井标定并通过数学拟合的方式求取校正量。对标准井标定环境和实际测井环境的差异进行了分析,并提出了相应控制措施;同时对工程深度、录井深度和测井深度的误差产生原因及现场测井深度的检查方法进行了探讨。
