摘要
通过分析页岩油气水平井测井难点,对水平井测井技术在页岩油气井中的应用进行研究。对湿接头工具进行多项技术改造和成功试验,提高了水平井测井的成功率和时效。从测井资料时效性、可控性以及技术的成熟度、施工队伍和施工经验等方面考虑,湿接头式水平井测井技术是当前页岩油气水平井测井的最佳选择。对长水平井段、小井眼和各种复杂井况(高压气井、起下钻困难井等)以及从井控安全方面考虑,采用无电缆存储式测井技术解决方案。
Based on analyzing the difficulties of horizontal well logging in shale well, researches have been done about the applicability of the horizontal well logging in the shale well. A number of technical improvements and successful experiments of wet-joint tools boost the success rate and efficiency of the horizontal logging. Wireless memory logging has just been developed in recent years and expanded quickly for its special advantages without the need of cable connection. The log practices prove that wet-joint logging method becomes the optimal choice due to the better time-efficiency and controllability of logging data, better log technologies and logging crews, etc. But the wireless memory logging is a better choice in the case of long horizontal-section, slim- hole, bad hole conditions （such as high pressure gas well, hard trip, etc. ） and well control and well safety.
