随着油气勘探开发的需要,定向井越来越多的出现在我们的视野中,从钻井工艺上来讲,定向井的施工难度比常规钻井难度要大,对录井作业也提出了更高的要求,只有完善常规录井技术,寻求新技术来克服定向井中给录井带来的各种难题,才能满足日益成熟的钻井施工中的需求。此文针对定向井的钻井及录井特点,对定向井中录井遇到的技术难题进行分析,结合长时间的现场实践经验,总结出了一套实用的方法,对常规录井方法进行了一些改进,对油气田勘探开发现场录井具有一定的参考价值。
With the need of oil and gas exploration and development, more and more directional wells appear in our field of vision. From the point of view of drilling technology, directional well construction is more difficult than conventional drilling, and also puts higher requirements on logging operations , Only to improve the conventional logging technology and seek new technologies to overcome the various challenges posed by mud logging in directional wells can we meet the needs of the increasingly mature drilling construction. In this paper, according to the characteristics of directional well drilling and mud logging, the technical problems encountered in mud logging in directional wells are analyzed. Combining with the long-time field practical experience, a set of practical methods are summarized, and the conventional mud logging methods are carried out Some improvements have certain reference value for oil and gas field exploration and development on site logging.
