油田开发规划多目标产量分配优化模型及其应用

Optimal Multiobjective Output Structure Models and Its Application In Oilfield Development Programming System

利用功能模拟原理(微分模拟方法及神经网络方法)建立的油田开发指标关联关系[1、2],研究并建立了油田开发规划中的产量最大,成本最低,效益最好的多目标产量分配优化模型。这些优化模型成功地解决了油田的总产量及对应的工作量成本等其它开发指标最优地分配到各二级开采单位的产量最优分配问题,将模型应用于国内某中后期开发油田的开发规划中产生了较好的经济效益。

On the basis of the establishment of the correlative relationship^() of the development index of the oilfield by use of functional simulation theory, such as differential simulation method and NN method , the authors study the oilfield and set up the optimal distribution models of oilfield development programming with different goals,including maximum oil output minimum cost and maximum economic benefit, which solve the optimal distribution problems successfully with total output and the corresponding workload and other (development) indexes of the oilfield. The satisfactory economic benefit can be obtained when the models are applied to the development programming in some mid-later stage oilfields.
