以秦皇岛某油田北区 NmⅠ3 砂体为对象,在系统分析岩心资料、密井网测井资料、生产动态资料的基础上,运用储层构型基本原理,将研究区复合河道划分出河流相五种单一成因砂体,同时根据单河道的识别标志和河流相砂体的对比模式,把研究区NmⅠ3复合砂体细分为了3期单河道,明确了单河道的沉积微相,阐述了单河道内部剩余油分布规律.
以秦皇島某油田北區 NmⅠ3 砂體為對象,在繫統分析巖心資料、密井網測井資料、生產動態資料的基礎上,運用儲層構型基本原理,將研究區複閤河道劃分齣河流相五種單一成因砂體,同時根據單河道的識彆標誌和河流相砂體的對比模式,把研究區NmⅠ3複閤砂體細分為瞭3期單河道,明確瞭單河道的沉積微相,闡述瞭單河道內部剩餘油分佈規律.

This paper, focusing on the NmⅠ3 sand body in the Northern Block of QHD32-6 oil field, uses the basic principles of reservoir architecture to divide the complex channels of the researched area into five types of single fluvial sand bodieson the basis of system analysis of cores, logging of dense well patterns and production behaviors; meanwhile, according to the recognition marks of single channels and the comparison patterns of fluvial sand bodies, this paper subdivides the complex sand bodyNmⅠ3of the researched area into three-staged channels, defines the sedimentary microfacies of single channels, sets forth the distribution rules of remaining oil within single channels, and therefore provides reliable geologic bases for the follow-up developmental adjustment of oil fields.
