中文摘要:
      对于已经进入注水开发中后期的油藏,开展储层构型研究是精细化油藏描述、深化剩余油分布认识的必要举措。本文以靖边油田梁镇区域延9曲流河储层为研究对象,结合岩芯、测井等资料,通过密井网解剖,识别不同级次的构型界面并分级次细分构型单元。本研究在梁镇区域主力油层延92-1单层内部划分出了3—5级构型界面;延92-1小层同期单河道之间以孤立式、对接式为主,不同期次河道垂向上以叠加式、切叠式为主,该小层整体上呈侧向拼接-垂向切叠式复合河道结构形式;在单河道内部识别出3个单一点坝,同时,在点坝内部识别出3个侧积层,4个侧积体构型单元。本次储层构型单元划分研究可以为下一步储层构型定量解剖及剩余油挖潜提供地质依据。
英文摘要:
      Reservoir configuration study, refining reservoir description and deepening understanding of distribution of remaining oil are the necessary measures for the reservoir under condition of middle-late water-injected development stage. This paper deals with reservoirs of Yan 9 meandering river in Liangzhen area of Jingbian oil field. Combined with data of core and well log and dissection of closely spaced well met configuration interfaces in different sizes are recognized and different configuration units subdivided. In the single layer Yan 92-1, the main oil layer of Liangzhen area are divided 3-5 configuration interfaces. The layer Yan 92-1 is mainly, isolated or abutted in contemporary channels, in un-contemporary channel overprinted or sliced vertically, generally abutted laterally and sliced vertically. In the single channel are recognized 3 single pint bars and 3 lateral accretion shale beds and 4 accretion sand bodies in the point bar. Such reservoir configuration unit division will provide geological basis for the next quantitative analysis of reservoir architecture and tapping of the remaining oil.
