摘　　要：采用野外露头、岩心描述、裂缝磁定向等方法研究低渗透油田不同类型裂缝的发育程度、影响因素及其对储层的渗流响应。综合应用差应变、波速各向异性岩心应力测试技术和测井解释技术 ,结合有限元模拟技术和现场微地震监测等手段对地应力分布进行描述 ,并对大庆油田地应力类型及分布规律进行系统研究。同时 ,在地应力及裂缝对油田注水开发中的作用方面进行了深入探讨。Taking eastern and western low permeability reservoirs of Daqing placanticline as working areas,adopting field outcrops,core description data and fracture magnetic oriented method,etc. to classify the fractures of the working area,studying the developing degree of different types of fracture,influence factor and response of the reservoir seepage.At the same time,comprehensively using different strain wave,core stress detecting technique of wave velocity anisotropic and well log interpretation, combined with finite element simulation and the field micro-seismic observation to study the stress distribution and to make description.The distribution rule of the structural fractures is predicted and the types and distribution rule of the ground stress studying is made systematically. Besides,the effect of the ground stress and the fractures in Daqing oilfield water flooding development is further discussed.
