改进灰色预测在油田多目标规划决策中的应用

建立了S油田勘探、开发、炼化、机械、公用工程等多个部门和全局的非线性多级目标优化规划模型,应用关联分析、改进灰色预测、回归分析求取规划模型的约束方程并线性化;编制了相应的计算软件,使之快速预测和优化油田各部门“九五”各年的投资和产值;并将优化结果与油田过去或计划值加以对比,给油田规划决策带来一定的参考。

Application of Gray Prediction to Multiobjective Programming in An Oil Field

Optimal programming is performed to an oilfield on its exploration, development, refinery and chemical engineering, mechanical engi-neering, public engineering, and poly-economy. Based on the analysis of available data, the critical factors, decisive variables andobjectives are defined and multi-objective planning models established. By means of correlation analysis, gray prediction and regres-sion analysis, the constraining equations for the models are obtained. With the computing software provided, predictions of the yearlycost and profit for the individual executive departments as well as the oilfield as a whole can be quickly and conveniently made.
