方位伽马在水平井地质导向中的应用

Application of Azimuth Gamma in Horizontal Well Geosteering

近些年出现很多大斜度井与水平井,相应推动了随钻测井技术发展,其中至关重要的测量内容是方位伽马测井,这部分测量数据体现出明显方位性,在合理运用自然伽马的基础上,提供了地质导向服务,从而把握地层状况。因此,根据方位伽马资料,开展方位伽马在水平井地质导向中应用的研究具有一定现实意义。

In recent years,there are many highly deviated wells and horizontal wells,which have accordingly promoted the development of logging while drilling technology.The most important measurement content is azimuth gamma logging.This part of the measurement data reflects obvious azimuth.Based on the rational use of natural gamma,geosteering services are provided to grasp the stratum status.Therefore,based on the azimuth gamma data,it is of practical significance to carry out the research on the application of azimuth gamma in horizontal well geosteering.
