摘要: 储层非均质性研究是精细油藏描述的核心内容,自产生以来已经取得了显著发展。阐述了储层非均质性研究的发展过程,概述了储层非均质性的分类及描述,并系统总结了目前研究储层物性特征和储层非均质性的方法,包括有储层野外露头分析、沉积体系分析、层次界面分析、结构单元和流动单元分析、高分辨率层序学研究、统计学方法以及现在比较推崇的劳伦兹曲线法等,指出了描述储层非均质性的相关参数和应用的关键,以期为老区块的剩余油开发以及新探区油气开发有利区带的预测提供科学依据。Abstract: The research of reservoir heterogeneity has remained as the core of fine reservoir description since its appearance, and has achieved remarkable progress so far. This paper briefed the history of the reservoir heterogeneity research, summarized its classification and description scheme, and concluded with the state of the art methods for the research of reservoir properties and heterogeneity, including the description of outcrop, sedimentary system analysis, level interface analysis, structural unit and flow unit analysis, high-resolution sequence study, statistics method and Lorentz curve method which is now commonly used. Key parameters and their applications in reservoir heterogeneity description are emphasized in order to provide a scientific basis for the residual oil exploitation in old blocks, and the forecast of favorable zone in new oil and gas exploration areas.
