基于控制论的油田开发五年规划模型及其应用

Five-year Programming Model of Oilfield and Its Application Based on Control Theory

由于油气系统的动态性和复杂性,长期以来油田的五年规划基本上都是采用逐年规划累加来进行代替,整体优化性有待提高。本文从整体优化的角度出发,将整个油气开发系统按其产量构成划分为若干个子系统,在研究总产量与其分项产量之间递变规律的基础上,结合功能模拟建立了油田产量开发系统的状态转移方程,并在此基础上利用目标规划建立了油田五年规划模型。实际应用表明,该模型能很好的解决油田开发的五年规划问题。

Oilfield developers usually employ the iteration of annual plan model to substitute for the five-year plan model because of the dynamic and the complexity of petroleum system, whose global optimality needs improving. According to the above problem, this research firstly divides the petroleum development system into three subsystems according to the structure of oilfield output, and then sets up the state transfer equations of oilfietd development system by embedding the function simulations and the transfer rule between the total output and the subentry outputs. Next, a five-year programming model is given based on goal programming. Finally, a practical application shows this method can resolve the oilfield five-year programming problem well.
