摘要
新疆油田六中东区砾岩油藏非均质性极强,部分层系存在明显水流优势通道,严重影响注水开发效果。运用油藏数值模拟方法,利用生产动态数据识别了水流优势通道,结合剩余油分布研究,优选了18注28采s37层系开展深部调驱先导试验,设计了高强度缓膨颗粒、常规体膨颗粒、凝胶等段塞式组合,优化了配方,现场应用增油效果明显,达到了调驱目的,对同类油藏的开发具有实际指导意义。
The conglomerate reservoir in east Liuzhong district of Xinjiang oilfield is highly heterogeneous.There are obvious preferable flow channels in part of the layers,which adversely affect waterflooding effect.Reservoir simulation has been carried out with production performance data to recognize preferable flow channels.Combined with residual oil distribution research,18 injectors and 28 producers in the s 3 7 layer system were chosen to conduct a pilot test of in-depth profile control and flooding.The designed slug flow included high strength retarded swelling particles,conventional swellable particles and gel,which were prepared with optimized formula.The pilot test has obtained notable incremental oil,achieved the goal of profile control and flooding,and is instructive to similar reservoir development.
