摘　　要：大庆外围油田以低、特低渗透储层为主，天然裂缝比较发育。针对储层裂缝对油田注水开发效果影响较大的问题，通过分析研究外围油田裂缝监测数据资料，深入开展了储层裂缝表征、预测及综合描述方法研究，研究了双重介质储层裂缝建模方法，形成了一套完整的低孔低渗储层裂缝定量描述方法，建立了裂缝网络模型及双重介质模型，实现了裂缝几何模型与等效介质模型转换，初步解决了储层裂缝地质建模技术难题。其研究成果在油田开发中得到广泛应用，取得较好的开发效果和经济效益，对非均质裂缝型油田精细开发调整具有重要指导意义。Daqing peripheral oilfields are mainly characterized by low-permeability ＆ ultra-low-permeability reservoirs and well-developed natural fractures. In the light of the issue of serious influences of the reservoir fractures on the performances of oilfield water flooding, with the help of the analyses and studies on the monitored data of the fractures, the method researches on the fracture characterization, forecast and comprehensive describing method are deeply carried out, and moreover the dualporosity media fracture modeling approach is studied, thus a set of com- plete quantified characterizing method of low-porosity and low-permeability reservoir fractures is established, the fracture network model and dual-porosity media model are built, so the geometric model of the fractures can be converted into equivalent media model, finally the technical problems of the geological modehng for the reservoir fractures is generally solved. The study achievements have extensively applied in the oilfield development and the much better social and economical effects have been acquired. In a word, the achievements have possessed important guiding significance for the fine development adjustment of heterogeneous fractured oilfields.porosity media
