剩余油分布及其挖潜研究综述

介绍了国内外剩余油分布的研究现状，从微观规模和宏观规模2个角度对剩余油研究技术进行了综述，微观规模常用的研究技术主要有物理模拟、计算机模拟等，宏观研究常用技术有测井解释、三维地震、流动单元划分等。认为不同的地质环境和开发方式会导致不同的剩余油分布模式，不同油田、不同区块分布模式不同。影响剩余油分布的主要因素中，储层因素是内在的，开发因素是外在的。概括介绍了我国部分油田剩余油挖潜的一些常用技术，认为应主要从改善储层非均质性的地质角度和调整注采状况的开发角度入手，采用动态、静态结合和多学科结合的方法挖潜剩余油。

Residual oil distribution and potential tapping study

This paper introduces the current actuality of the study of residual oil distribution in the world,addresses the technology of the study from the points of both micro and macro scale: the micro scale study includes physical modeling and computer modeling;and the macro scale study includes logging interpretation,3D seismic and flow unit division.It is thought that different geological environment and development scheme will lead to different mode of residual oil distribution.Among the factors affecting residual oil distribution,reservoir factors are interior,and development factor are exterior.Conventional technologies for tapping residual oil are summarized.It is believed that residual oil shall be produced by starting with improving reservoir heterogeneity and adjusting injection-production status,and by combining dynamic,static and multidisciplinary methods.
