摘　　要：凤冈地区是黔北最富有基质的页岩气资源地区之一,燕山期又是该区内构造变动期中最强烈的构造运动时期。通过凤参1井页岩力学实验和声发射测试结果,应用有限元法对凤冈地区燕山期进行了构造应力场数值模拟。根据摩尔-库伦准则,进行裂缝预测。预测结果与声发射所测的燕山期古应力期次数值范围基本吻合。Fenggang area is one of the most rich shale gas resources in northern Guizhou, and Yanshan period is the most intense tectonic movement in the period of tectonic movement in the region. By means of the finite element method, the numerical simulation of tectonic stress field of the Yanshan period of Fenggang area is carried out by the finite element method, and the results of shale mechanics and the Fengcan 1 well acoustic emission test are carried out. According to Mohr-Coulomb criterion,and the fracture prediction. The predicted results are in agreement with the numerical range of the Yanshan period in the period of the paleo stress period measured by acoustic emission.
