摘要
本文以八面河油田沙三段为例,从测井解释储层参数、储层砂体韵律性、沉积相分析和非均质类型研究入手,探讨了层内非均质性类型及其特征。研究表明该区层内非均质类型共有箱型、钟型、漏斗型、中间突变型和复合型等五种。沙三沉积期不同微相非均质程度不同,席状砂、远砂坝、水下分流河道等微相属强非均质体,河口砂坝非均质程度弱,属最好储集层。
This article takes the third member of the Sha hejie formation in the Ba mianhe oil field as an example. Study logging interpretation of resevior parameter, rhythm of resevior body and analysis of sedimentary facies with heterogeneity types, discusses of in-layer heterogeneity and its characters, the conclusion indicates that the in-layer heterogoeneity are trunk model, bell model, filler model, middle abruptly changing model and composite model. Differs heterogeneity of the all microfacies of the three member of the ShaHejie formation, sheet sand, distal bar and subaqueous distributary channel are all seriously heterogeneity; distributary mouth bar is weak heterogeneity,so it＇s the best resevior.
