【摘要】 《民南区块精细油藏描述研究》主要是针对民南区块扶杨油层已接近中高含水期的开发现状及矛盾,为了控水稳油、挖掘油藏潜力而提出来的。随着新民油田开发的不断深入,油层非均质性及开发矛盾逐渐显现出来,油层水驱及剩余油分布变得更为复杂。文中通过研究斜井校直、小层细分沉积单元及全区统一系统对比、岩石相分析及测井微相模式建立、开发密井网平面沉积微相及单砂体精细解剖、研究区沉积模型建立等内容,采用了斜井校直技术、沉积单元划分与对比技术、岩心相识别及测井微相建模技术、沉积单元级平面微相综合研究技术等关键技术对民南区块进行了研究。取得重要成果和结论:建立了全区统一的高分辨率等时地层格架;完成了34个沉积单元面沉积微相划分及单砂体精细分布图的研究;新民油田物源方向明显为西南,属河控浅水三角洲沉积体系;研究成果应用在生产实践中取得非常好的效果。更多还原

【Abstract】 "Fine reservoir description of Xinmin Southern block"primarily directed at the status and the contradictions of the development of Fuyang reservoir of the Xinmin Southern block which is close to high water cut stage of the development,in order to control water-stable oil,mining and reservoir potential of the initiative.With the deepening of Xinmin oil field development,reservoir heterogeneity and the development of contradictions gradually appearing,water-drive reservoir and distribution of remaining oil are become more complicated.In this paper,by studying the inclined shaft alignment,small sub-layer deposition units and a uniform system for the whole region contrast,facies analysis of cores and logging set up micro-phase model,the development of dense well and flat sedimentary microfacies fine anatomy of a single sand body of the study area such as deposition modeling,the South Block were studied by these method.deposition unit used classification and correlation technology,the identification of core and logging micro-phase modeling techniques,the unit class plane Microfacies General research techniques,the heterogeneity and analytical techniques such as flow unit of the public key technology.Key results and conclusions obtained:Set up a unified whole region,such as high-resolution stratigraphic framework:completed the 34 units divided into surface sedimentary microfacies and fine single sand body distribution of the study;Xinmin oilfield obvious source for the south-west,which is river delta in shallow water control system:application of research results in practice in the production of very good results.更多还原
