摘要(Abstract)：
苏德尔特油田布达特群裂缝型油藏是海拉尔盆地的主力产油层之一,采用常规规模压裂工艺,油井措施有效期短,增产效果不理想。通过分析储层天然裂缝发育特征和变质岩岩石力学特性,确定了体积改造压裂方式,现场应用了滑溜水混合缝网压裂、大规模冻胶体积压裂等2种压裂工艺,效果显著。分析结果证明,扩大改造规模并提供有效支撑是裂缝型油藏增产改造的发展方向。
The fracture-type reservoirs of Budate group are the main producing pays in Suderte Oilfield in Hailar Basin.Using the conventional size of fracturing technology,the effective period of the stimulated oil wells is shorter and the effects are not ideal.Through the analyses of the developed characteristics of the natural fractures of the reservoirs and the lithomechanical properties of the metamorphic rock,the fracturing forms of the volume stimulation are determined and furthermore two types of fracturing technologies including slick water-mixed network fracturing and large-scale gel volume fracturing are applied in the field and then much obvious effects are achieved.The results of the analyses show that enlarging the stimulation size and providing effective propping capacity are the development orientation of the stimulation of fracture-type oil reservoir.
