摘要
油气藏描述是油气田勘探、开发过程中一项利用获取的地下信息来研究和定量描述油气藏开发地质特征并进行评价的新技术。本文在查阅大量国内外资料的基础上,总结了不同阶段油气藏描述的主要任务、研究内容及相应的技术方法。作为油气藏描述的最终成果,储层地质建模是近年发展起来的对油气储层定量表征和刻画的技术。本文从储层建模的基本理论入手,在简要介绍储层建模的类型的基础上,重点论述了国内外已知的几种储层建模技术和方法及各种方法的适应性,同时详细列举了储层建模的步骤,并对储层地质建模应用范围和效果进行了简要评述。本文对于全面了解油气藏精细描述及储层地质建模的研究内容、方法、理论基础及研究实施步骤具有重要的指导意义。
Abstract
Reservoir description is a new technology that is to study and quantitatively describe the geological characteristics of reservoir development, and to evaluate them, through application of the obtained underground information, during oil/gas exploration and development process. Based on the consulting a large number of domestic and international data, the main task, research content, and respective technical methods of oil / gas reservoir description at various stages are summarized in this paper. At the same time as the final results of reservoir description, reservoir geological modeling is a technology that, developed in recent years, quantitatively describes and depicts oil/gas reservoirs. Proceeding from the basic theory of the reservoir modeling , on the basis of a brief introduction to the type of reservoir modeling, several known reservoir-modeling techniques and methods at home and abroad, and their adaptability of various methods are mainly discussed in the paper. Detailed steps of reservoir modeling were enumerated in the paper, and the field of application and effectiveness of reservoir modeling are briefly reviewed. This paper has important significance for prehensive understanding of the content, methods, theoretical basis, and implementation steps of researches on the fine description of reservoirs and reservoir modeling.
前言
一般认为精细油藏描述是指油田进入高含水期和特高含水期后、对油田挖潜和提高采收率,以搞清剩余油分布特征、规律及其控制因素为目标所进行的油藏多学科综合研究[1]。在油田开发后期进行的精细油藏描述,具有精细程度高、基本单元小、预测性强、与动态结合紧以及计算机化程度高的特点。其主要目标是建立油藏预测地质模型[2-3]。
储层建模技术近年发展起来的对油气储层定量表征及对各种尺度的储层非均质性的刻画的技术。它综合利用各种地质、地震、测井和动态数据,并用地质统计学的方法对各种储层参数进行井间预测,建立定量精
