摘要:

物质平衡方程是解释和预测油藏动态的基本方法之一,求解物质平衡也就成了油藏工程师面临的实际问题。
现有油藏物质平衡计算往往借助于成熟商业软件来完成,其计算成本较高,而传统的物质平衡计算进行线性化处理后
常需多次手工试算,计算效率较低。把油藏基本参数作为决策变量,并把物质平衡计算描述为一非线性规划问题,对
这一问题进行规划求解,则可以在已知少数实测油藏压力以及生产数据的情况下,自动求得较准确的油藏基本参数、
水体平均压力变化情况及水侵动态。与前人研究对比后发现,该方法可操作性强,计算结果可靠。

Abstract:

Material balance equation(MBE)is one of the basic tools to explain and forecast the reservoir dynamics. It is
truly an actual problem that reservoir engineers need to be faced. Prevalent commercial software are commonly to be used to
solve the MBE currently,but which cost too much rather than the traditional methods,however,it always need to be linearized
first and usually to apply manually an adopting cut-and-try method,so it′s efficiency is comparatively low. When knowing
a little reservoir pressure and production data,taking reservoir basic parameters as decision variables and describing MBE as
a nonlinear programming and utilizing the function of solving multi-variety′s programming problems provided programming
module could automatically get a accurate basic parameters and average pressure and the water influx behavior of aquifer.
Comparison with the calculation result of formers,it is reliable and have highly operability.
