注水开发稠油生产井劈产方法研究

以多孔介质渗流力学、油气藏开发地质学、油藏精细描述技术、开发动态分析方法、流动单元、油田非均质对策论和油藏流场为基本理论基础,通过对注水开发方式生产的稠油油气藏所表现出的动态特征研究,首次提出了稠油生产井的劈产方法。在已经全面注水开发的稠油油气藏,将由应用该方法所得的计算结果与油藏特征再认识结论对比、综合分析,劈产分析可以揭示油气藏动态特征及其变化规律性,表明本方法可行、合理;本项工作的结果,不仅对实际稠油油气藏的动态分析具有重要意义,而且为注水开发稠油油气藏稳产高产技术的优化设计奠定了扎实的理论基础。

A Splitting Methods on Production Wells in Water Flooding Heavy Oil Field

A splitting method has been constructed , that could calculate single reservoir production and using it to analysis water flooding heavy oil reservoirs dynamic or narrowly character reservoir. The method is based on Porous Media Seepage Theory and Flow Unit Theory and Oilfield Teterogeneity Game Theory and Flowing Concourseto Theory to build models, based on Reservoir Development Geological Theory and Fine Reservoir Description Theory to optimize and screening parameter, and based on Develop- ment of Dynamic Analysis Theory to analysis the actual reservoir. In an example of water flooding heavy oil reservoir, the water injection well have a injection profile, there are eight production wells. When have alculated single reservoir production of wells, contrasting the production profile with the injection profile is successful. The results of the research show that the studing is significative .
