Abstract
There are difficulties in horizontal well log interpretation and evaluation because of the survey data error of vertical depth of while drilling logging and wireline logging in horizontal well.We compare and analyze horizontal well trajectory of 32 wells in Changqing oilfield,calculate one borehole trajectory of while drilling logging survey and wireline logging survey by average angle method.From the logging technology,the depth measurement and precision measuring of instruments,we analyze the cause of depth error.The error of borehole trajectory between while drilling logging and wireline logging is mainly due to the depth of measurements.The well trajectory error correction methods are proposed.The actual calculation results show that well trajectory is closer to actual after applying the method,which has great significant to the relation analysis of well trajectory and formation and the evaluation of horizontal well logging data.关键词
