摘　　要：随着临兴西区致密砂岩气藏勘探开发逐步深入,水平井成为提高单井产量的重要手段,而水平井钻探成功率和储层钻遇率很大程度上受地质导向技术的制约。利用LXX23-21H水平井的成功案例对临兴西区水平井地质导向技术进行总结,提出一套基于近钻头方位伽马随钻测井技术的地质导向方法,认为准确选择标志层、精确着陆和水平段导向控制是水平井钻探成功的主要因素。该方法可指导区内后续水平井施工,提高开发效率和效益。With the deepening of the exploration and development of tight sandstone gas reservoirs in the Linxing West gas filed,horizontal wells have become an important means to increase single well production.However,the success of horizontal well drilling and the rate of reservoir encounter are greatly affected by geosteeing technology.Based on the successful case of LXX23-21H horizontal well in Linxing west area,a set of geo-steering method based on at-bit azimuth gamma logging while drilling is proposed.It is believed that accurate selection of marker layers,efficient landing and horizontal section steering are the main factors for the success of horizontal well drilling.This method provides guidance for the subsequent horizontal well construction in the area and improves the development efficiency and benefit.
