摘要
Abstract
There are some difficulties in logging operations in the ultra-deep sidetracked horizontal wells in Tahe oilfield, such as poor wet-connector docking, strict tool temperature-resistant performance,limited logging tool combination and unknown downhole risks while conveying the drilling strings. To solve the above problems, proposed is a new and more complete ultra-deep sidetracked horizontal well logging technique and its supporting logging program, which includes wellbore preparation, tool performance test and combination, logging process control and protection of the wellhead cable. If the downhole temperature is above 175 ℃/140 MPa, we should use higher temperature-resistant logging tool; the tool's temperature performance must be carfully tested before logging operations; if the high temperature drying over testing method is used, the tool's temperature should be warmed up to 175 ℃. The anti-collision device of well head cable can effectively protect the logging cable during the drilling tool conveying. Close cooperation a-mong the in-situ logging units is also important for obtaining complete and accuracy log data. This technology has been applied in Tahe oilfield for 40 times, and the success rate of one log run is 90%. This technology can not only be used to the log operation of the horizontal wells but also to logging operation of some complex deep straight wells.关键词
