油藏动态跟踪模拟系统研制

The Development Of Dynamic Tracing Reservoir Simulation System

在微机上开发了一套油藏数值模拟系统。该系统可以直接从生产数据库中调用所需要的数据 ,利用 Kriging方法利用形成油藏数值模型。同时对数值模拟方程的求解方法作了改进 ,利用正交极小化方法 ORTHMIN求解方程 ,提高了计算的速度和精度。利用重启技术实现了油藏历史的分时段拟合和动态跟踪。

The dynamic tracing reservoir simulation system id developed on personal computer. This system can get production datum from oilfield development date-base directly, build up the reservoir numerical model by Kriging method. At the same time, it improves the method of solving difference equation by Orthmin algorithm, makes the speed and accuracy if different periods and trace and calculate the reservoir status.
