摘　　要：针对樊庄地区高阶煤含气量高、产气量低的特点,煤层压裂改造可有效的将井孔与煤层天然裂隙连通起来,从而加快气体解吸速率,地应力场是影响该区煤层气开发效果的重要因素。本文利用地球物理测井技术,总结出一套适用樊庄地质条件和煤层气勘探开发特点的地应力场评价方法,优选煤层气有利开发部署区,为煤层气有利开发区水力压裂施工提供依据,取得了较好的生产效果。Since the characteristics of the high gas content and low gas production of high-rank coal in Fanzhuang,the fracturing of coal seam can effectively connect the well hole with the natural fracture of coal seam,thus increasing accelerating the gas desorption rate.The analysis of ground stress field is an important factor affecting the development effect of coalbed methane in this area.In this paper,by using geophysical logging technology,a set of evaluation method of ground stress field suitable for Fanzhuang geological conditions and the characteristics of coalbed methane exploration and development has been explored,so as to optimize the favorable development and deployment areas of coalbed methane,and provide a basis for the construction of hydraulic fracturing in favorable development areas of coalbed methane,which has achieve good production results.
