摘　　要：随着我国能源结构的不断优化,页岩气的勘探开发已被列入了国家战略开发范围。由于页岩气藏储层特征决定,采用水平井工艺可大大提高页岩气开发效率得到了极为广泛的应用,井壁稳定问题作为影响水平井开发效果的重要因素之一。文章以四川威远地区页岩气藏为研究对象,重点分析页岩气水平钻井过程中影响井壁稳定的因素,并提出相应对策。With the continuous optimization of China's energy structure,the exploration and development of shale gas has been included in the national strategic development scope.Due to the determination of reservoir characteristics of shale gas reservoir,horizontal well technology can greatly improve the efficiency of shale gas development and has been widely used.Wellbore stability is one of the important factors affecting the development effect of horizontal Wells.Based on the horizontal well development of shale gas reservoir in Weiyuan area of Sichuan province,this paper focuses on the factors affecting wellbore stability during horizontal drilling of shale gas,and puts forward corresponding countermeasures.
