地震约束建模技术在油藏模拟中的应用

研究剩余油分布，提高油气采收率是东部油田开发工作的主题，在建立精细地质模型基础上进行精细油藏模拟研究是有效确定油藏剩余油富集区的主要手段。胜利油田主力油田区开发相继进入特高含水期，油层大面积水淹，注入水波及面积进一步扩大，因此，寻找剩余油、提高采收率成为油田开发工作的重点及难点，也是稳产的关键。在总结胜利油区前五轮精细油藏模拟工作的基础上，本文尝试对精细油藏模拟做系统分析，从保证模拟精度的地质建模出发，对影响构造模型、储层模型精度的相关技术进行分析，以期指导其他油田开发后期油藏地质模型的建立及油藏模拟研究。

Application of seismic constrained model-building technique to reservoir modeli ng.

Enhancing oil recovery by study of remaining oil distribution is the subject of oil-field development in east region,the fine reservoir modeling study on the basis of fine geologic model-building is key tool of effectively determining th e abundance zone of remaining oil in the reservoir.The main oilfields of Shengl i oil-region have come into high watercut period successively,the reservoir ha s been waterflooded in large scale and the waterflooded area and volume have bee n further enlarged,so looking for remaining oil and enhancing recovery become the key and difficult points in development of oilfield and are also the key of stable production at the same time.On the basis of summing up former 5 rounds of fine reservoir simulation in Shengli oilfield,the paper try to systematical ly analyze and study the fine reservoir simulation.Starting from geologic mode l-building technique assuring the simulation precision,the paper analyzed rele vant techniques that have a impact on precision of structural model and reservoi r model,hopping to guide geologic model-building of reservoir and study of res ervoir simulation for other oilfield in the later stage of development.
