摘要: 储层地质模型是表征地质体规模、储层建筑结构与流体分布特征的综合体,是地质研究的最终成果和数值模拟的基础数据体。回顾并总结了中国储层地质建模30年来的发展历程与阶段、地质模型的类型划分与主要特点以及中国储层地质建模技术的主要进展。前20年,在引进、吸收国外建模理念和技术的基础上,形成了中国储层地质模型的基本框架、流程和步骤;建立了扇三角洲、辫状河等储层原型地质知识库,开展了河流相储层分级构型研究,推动了定量地质学的发展;分构造背景和储层类型建立模型,在随机模拟方法和技术上取得突破。近10年来,建模手段日趋丰富,方法不断进步,同时随着开发阶段和开发对象的深刻变革产生了3个方面的重大变化:①非常规储层开发逐渐受到重视,针对非常规储层的地质建模技术得到了大力发展与广泛应用;②许多油田进入中-高含水期或开发后期,针对老油田的储层表征与建模技术不断深化;③随着天然气工业的快速发展,形成了一套针对天然气开发需求的油藏描述与地质建模技术。

Abstract: Reservoir geological model is a comprehensive body that characterizes the scale of geological body, reservoir structure and fluid distribution characteristics. It is also the final result of geological research and the basic data system for numerical simulation. This paper reviews the development process and stages of geological modeling in China in the past three decades, and summarizes the classification and main characteristics of geological models and the major progress in geological modeling technology.In the first stage of 20 years, based on introducing and studying the foreign modeling concepts and technologies, the basic framework, processes and steps of geological modeling have been established in China; a prototype geological knowledge database for reservoirs such as fan delta and braided rivers has been built, and relevant studies have been carried out on the hierarchical configuration of fluvial facies reservoir, thus promoting the development of quantitative geology; a series of geological models have been established according to the different structural background and reservoir types, and breakthroughs have been made in stochastic simulation methods and technologies. In the nearly 10 years, the methods of reservoir geological modeling has been developed, and continuously improved. Meanwhile, with the profound revolution in the development stage and development object, three major changes occurred:first, unconventional reservoirs, as a exploitation target, have been gradually attracting attention, and thus the geological modeling technology for unconventional reservoirs has been vigorously developed and widely used; second, a large number of oilfields have entered the middle-high water cut period or late development period, and the reservoir characterization and modeling technologies for old oilfields have been continuously improved; third, the rapid development of natural gas industry has resulted in the appearance of a set of reservoir characterization and geological modeling technologies for meeting the needs of natural gas development.

Key words: reservoir geological model, quantitative geology, unconventional, middle-high water cut stage, natural gas
