油田开发多目标产量分配模型及其应用算法研究

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，研究并建立了油田开发规划的多目标产量分配优化模型。该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。针对非线性多目标规划问题，采用改进的Hooke-Jeeves算法求解，并将该模型及算法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。

Multiobjective Optimal Models of Output Structure and Its Algorithm in Oil Field Development Programming System

On the basis of the establishment of the correlative relationship of the development index of oilfield by use of functional simulation theory, such as differential simulation method and NN method , the authors researched 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 solved the optimal distribution problems successfully with total output and the corresponding workload and other development indexes of oilfield. Considering the non-linear Multi-objective models with restrictions, we used the improved Hooke-Jeeves algorithm to solve it, and the application of the algorithm and the models to development programming in some oilfields which were in the mid-later stage has obtained satisfactory economic benefit.
