Abstract: With development of computer technology, the reservoir modeling in China has experienced a process from hand-drawing to visible 3-D modeling. Geostatistic methods and stochastic modeling have been extensively used in reservoir prediction. In order to build more reliable geological model and prediction techniques suitable for the continental clastic reservoirs in China, geological prototype models and knowledge database of continental clastic reservoirs are being developed by means of studying outcrop analogues. With a series of satisfactory results,the geological modeling in China have gone through four phases, which are (1)quantitative conceptual modeling; (2) fast development of geological modeling; (3) emphatic development of geological modeling; (4) detailed study of outcrop reservoir.

Key words: geological model, outcrop, stochastic modeling, reservoir characterization

摘要： 随着计算机技术的不断普及和计算机运算能力的不断提高,我国的储层地质模型的建立经历了从手工作图到完全三维可视化的整体地质模型的建立。同时,在储层预测方面,也开始由一般的地质统计向随机模拟和预测的方向发展。在另一方面,为了建立更加准确可靠的地质模型,发展适合于我国陆相碎屑岩储层的预测方法,近年又开始了储层地质原型模型的建立和积累陆相碎屑岩储层的地质知识库,这是一项非常有意义的工作,并且已取得了相当的成果,该项技术的不断发展,预期将对我国储层表征起到很好的推动作用。回顾我国储层地质模型的发展历程,大致经历了以下几个阶段:(1)早期定量概念模型的建立;(2)地质模型的快速发展阶段;(3)地质模型的重点发展阶段;(4)储层露头精细研究。
