【摘要】：本文根据渤中34-1油田NmⅡ油组的井取心资料、测井资料、生产动态资料等,从研究区地质特征入手,通过精细等时地层对比以及沉积相研究,并综合运用储层地质学、层序地层学、沉积岩石学及石油地质学等多方面学科知识进行了三角洲前缘砂体储层构型的研究,最后结合生产开发中的动静态资料、构型研究成果分析了储层构型对剩余油分布的影响,以此指导油田的中后期开发、挖潜。通过追踪区域范围内的标志层及其测井响应、连井剖面对比、剖面闭合等方法对全区进行了精细地层划分与对比;采用分级控制的砂体内部建筑结构研究方法,纵向上细分沉积格架,平面上细分沉积微相、构型级次划分、复合砂体内部单砂体刻画等四个方面分级精细研究单砂体储层构型表征。通过储层构型研究得出四级构型界面限定的地质体可划分出水下分流河道、水下分流河道间湾两种单一构型单元,并对单河道砂体的纵横向延伸范围进行了定量计算,并将构型单元的空间组合关系进行了解释,共解释2种横向组合关系以及3种纵向组合关系,在油藏范围内分析了构型单元对剩余油分布的影响这5种情况。
[Abstract]:According to the Nm wells of oil group of Bozhong 34-1 oilfield coring data, logging data, production dynamic data, according to the geological characteristics of the study area, through the fine isochronous stratigraphic correlation and sedimentary facies analysis, and comprehensive use of reservoir geology, sequence stratigraphy, sedimentary petrology and petroleum geology and other aspects of knowledge study on the delta front sand body reservoir configuration, combined with the production and development in the dynamic and static data, configuration analysis of research results of reservoir structure influence on the distribution of remaining oil, in the late development stage, in order to guide the oilfield development. Through the tagging region layer and logging response, connecting well section, section closed method of fine stratigraphic division and correlation of the region; the hierarchical control sandbody architecture research method, the longitudinal subdividing sedimentary framework, plane fine sedimentary microfacies, The configuration of grading, four aspects of compound sand body sandbody characterization of fine classification of single sand body reservoir architecture characterization. Through the study of reservoir architecture that geological body interface four architecture defined can be divided into underwater distributary channel, underwater distributary bay two single structure unit, and the single river channel sand body in vertical and horizontal extension were calculated, and the relationship between the space combination configuration unit is explained, which explained 2 syntagmatic relation and 3 kinds of vertical relationship, these 5 kinds of circumstances affect configuration unit distribution of remaining oil in the reservoir analysis range.
