| 摘 要： | 对水平井进行水力压裂,一口井可以形成多条横向裂缝,增产效果比直井更明显,因此近年来水平井压裂应用越来越广泛.该文以ABAQUS软件为平台,采用流固耦合单元模拟岩石的应力渗流耦合行为,采用带有孔隙压力自由度的粘结单元模拟油层和隔层的破裂和扩展,射孔连接微环隙和横向裂缝,即假设了双向同时起裂和扩展的可能性.对大庆油田某水平...

| Abstract: | Multiple transverse fractures could be generated in the process of horizontal well hydraulic fracturing,which may achieve higher productivity than vertical well hydraulic fracturing,so more and more horizontal well hydraulic fracturings were performed in recent years.In this paper,fluid-solid coupling elements were used to describe the behavior of rock fluid-solid coupling,and pore pressure cohesive elements were employed to simulate the process of fracture initiation and propagation in oil and barrier laye... |
