油层开采实践表明,平面上同一河道砂体内部渗流能力存在差异。储层流动单元旨在揭示由油层物性不同造成的非均质性规律。以姬塬油田吴420区为研究区块,根据垂厚、渗透率、孔隙度、突进系数等参数,采取spss主成分分析法,合理制定各参数权重,对河流相储层进行了渗流单元划分,精细地揭示了河道砂平面非均质特征。
The practice of reservoir exploration shows that there are differences in the seepage capacity of the same channel sandbody in the plane. Reservoir flow units are intended to reveal the heterogeneity caused by the different physical properties of the reservoir. Taking Wu 420 area in Jiyuan Oilfield as a research area, according to the parameters of vertical thickness, permeability, porosity and jerk, the spss principal component analysis method is adopted to make the weight of each parameter reasonably. The percolation unit of the fluvial facies reservoir is divided , Reveals the inhomogeneous features of channel sand plane.
