摘要
针对丘陵油田西山窑组储集层低孔特低渗的油藏特征,结合注水开发动态,选取反映储集层物性、沉积特征及流体性质的主要参数,对流动单元进行了划分,共划分出E、G、M、P 4种类型。研究表明,流动单元的平面展布在一定程度上受沉积微相控制,不同类型的流动单元其渗流能力和储集能力差异较大,在生产动态特征方面表现为吸水、产液及含水特征存在明显差异。因此,注水开发阶段以流动单元为基础进行动态分析和潜力研究,有助于获得较理想的开发效果。
The reservoir in Xishanyao formation is characterized by low porosity and ultra-low permeability.Main parameters reflecting reservoir properties,sedimentary characteristics and fluid properties are selected according to water injection dynamic,and the flow units of the reservoir is divided into four types,including E,G,M and P4.The research indicated that the planner distribution of flow units is to some extent controlled by the sedimentary facies,and different types of flow unit have great difference in seepage capability and reservoir capability and it has obvious differences in production performance characteristics such as absorbent,produced fluid and water-bearing features.The dynamic analysis and the potential study based on the flow units at water injection stage are helpful to take good development effect.
