吐哈油田油藏数值模拟技术

THE TECHNOLOGY OF RFSERVOIR NUMERICAL SIMULATION IN TUHA OIL FIELD

数值模拟技术是吐哈油田近几年应用较广的一项新技术,已成功地应用于三大主力油田的各个开发阶段。本文系统地、概括性总结了该项新技术在油田开发各个阶段的研究对象及具体工作内容,重点介绍了整体模拟研究的思路和方法,特别是技术对策的敏感性分析和目标函数的引入,进一步完善了数值模拟工作体系,提高了模拟预测的精度。几年的开发实践也证明了本研究方法和思路十分有效且很适合本油田实际。

The numerical simulation is a new technology which has been used for several years,in each development stage of three major oil fields.This paper sums up systematically and briefly the study objects and the work content of the new technology in each development period.It gives emphasis to present the train of thought and method of integrative numerical study.It especially presents the sensitivity analysis of technical policy and use of object function.It further improves the working system of numerical simulation and predicting accuracy of simulation.It was proved with developing practice in recent years that this study method and the train of thought was very useful and effective in Tuha Oil Field.
