摘要:
以评价五里湾油藏长6油组储层的宏观非均质性,分析其对剩余油的控制作用为目的,综合运用测井及地质资料开展储层层间、层内及平面非均质性研究。结果表明:层内韵律性以正韵律和反韵律为主,夹层分布稳定; 层间隔层主要为2m左右的泥岩层或泥质粉砂岩层,层间砂体表现为4种垂向连通方式; 平面孔、渗参数变化明显受控于沉积微相和砂体的展布,水下分流河道物性条件好于河口坝微相。储层垂向上砂体的韵律性与渗透率非均质性对流体的渗流能力的影响,控制了层内剩余油的分布; 平面砂体的连续性以及不同成因砂体的物性变化是影响储层剩余油平面分布的重要因素; 层间隔层以及层间渗透率非均质性造成了合注合采过程中的层间矛盾,控制了剩余油垂向分布。
Abstract:
For evaluating and analyzing the macroscopic anisotropy and its controlling on the remaining oil distribution,the well logging data and geological information were comprehensively applied in this research of the intraformational,interlaminational and plane anisotropy.The results showed that the intraformational rhythm is mainly positive and reverse.The interlaminational interlayer is mainly an about 2 meter thickness of mudstone or siltstone.The interlaminational sand bodies have 4 kinds of connected manners in vertical direction.The changes in plane porosity and permeability are obviously controlled by the microfacies and distribution of sand bodies.The physical properties of the underwater distributary channel are better than the estuary dam.The intraformational remaining oil distribution is influenced by the fluid seepage ability controlled by the vertical sandbodies rhythm and the permeability anisotropy.The plane sand body continuity and the physical property change of the sand bodies with different formation cause are main controlling factors of the plane distribution of remaining oil.The interlaminational interlayer and the interlaminational permeability anisotropy,which control the remaining oil distribution,cause interlayer contradictions in the process of commingled production.
