油田开发二层规划优化模型研究

Research on optimization model for 2-step planning during oil field development

二层规划方法与理论是研究大系统和复杂系统的有效方法之一。从油田开发指标关联关系的建立出发,利用二层规划方法及理论对油田企业开发规划问题进行研究,并建立了以效益最好(定产量、定成本)为目标的油田企业优化模型。该优化模型成功地解决了油田企业产量分配问题以及采油厂各分项产量(通常含自然产量、措施产量、新区新井产量、老区新井产量)及对应的各项工作量及其它开发指标的最优构成问题,同时给出了模型的遗传算法步骤,并进行了实例分析。

The method and theory of 2-step planning are efficient in the research on large-scale system and complicated system. This paper, with the consideration of the establishment of the correlate relation among the development indexes for oil field, is about the application of 2-step planning method and theory to the problems of oil field development planning, and the optimization model, targeting at the best benefits （single rate, fixed cost）, is established. This model successfully resolves two problems： one is the production allocation of oil fields, and the other is the optimum composition of each component production （ generally including natural production, measure production, production from new wells in new areas and original areas） for each oil productive companies and the corresponding working capacity and the optimum composition of other development indexes. This paper also lists the genetic algorithm for the model, and example analysis is also listed.
