摘要
Abstract
In view of the unclear understanding of the reservoir heterogeneity of Chang 21 in Zhengsi block,the intra-,interlayer and plane het-erogeneity of the study area is studied in detail based on the results of reservoir physical property testing and logging data.The results show that the in-layer heterogeneity is strong in terms of sand body rhythm,permeability heterogeneity parameters and interlayer distribution,and the Chang 211 small layer has the strongest heterogeneity,followed by Chang 231 and Chang 221 small layers.From the perspective of sandstone density and interlayer distribution,the interlayer heterogeneity of Chang 231 is the strongest.On the plane,the sand body of Chang 21 reservoir has good connectivity,but the lateral variation is large and the heterogeneity is strong.In general,all the dimensions of Chang 21 reservoir show strong het-erogeneity,among which Chang 211 is the most heterogeneous,followed by Chang 231 and Chang 221.To clarify the heterogeneity of Chang 21 reser-voir in the study area is helpful to understand the spatial distribution law of oil and water in Chang 21 oil subgroup,and can provide theoretical reference for efficient oilfield development and remaining oil exploitation.关键词
