摘要: 结合松辽盆地南部长岭凹陷腰英台油田裂缝油藏的开发实践,对地应力场和天然裂缝场进行了定量分析,以油层构造为研究对象,建立了平面模型模拟构造应力场,并与实测地应力值相比较,从而得出应力场的分布特征。从储层裂缝形成的古构造应力场出发,根据弹性力学理论,应用岩石的破裂准则,确定并预测储层构造裂缝的组系、方位和密度。通过应力场和天然裂缝场的发育分布研究,确定现场试验井组,指导压裂改造和油田开发井网部署的设计优化和现场实施。Abstract: Combined with the development of fractured hydrocarbon reservoir of Yaoyingtai Oil field in the Changling Sag of the Southern Songliao Basin,the paper quantitatively analyzes the ground stress field and the natural fracture field,and sets up an areal model to simulate the tectonic stress field and compares it with the actually measured ground stress value by taking the reservoir structure as the study object so as to obtain the distribution characteristics of the stress field.Based on the palaeotectonic stress field formed in the reservoir fracture and the theory of elasticity,by using of the fracture criteria of rock,it determines and predicts the group,azimuth and density of the reservoir tectoclase.The study of the development distribution of stress field and natural fracture field determines the well groups for the field experiment and instructs the fracturing treatment and the design optimization and field application of the well pattern arrangement for the field development.
