摘　　要：本文据相似理论和方法,通过力学模拟实验,首次应用三维有限元法并综合钻探资料及地震成果,深入探讨了川东卧龙河构造形成机制、应力分布和裂缝发育规律及其与气藏富集的关系。研究结果与勘探实际吻合较好,为在该构造优选井位提供了有力的依据。In the light of similarity theory and method, through mechanical simulation test, the mechanism- forming, stress distribution and the relation between fracture growth law and gas pool accumulation of Wolonghe structure in East Sichuan are discussed by first time using tridimensional finite element and syntheizing drilling data and seismic achievements. The study result tallies with field exploration, thus providing basis for optimum seeking well location in the structure.
