油田产量构成二层规划模型及其应用

OIL PRODUCTION COMPOSITION BILEVEL PROGRAMMING MODEL OF OILFIELD AND IT′S APPLICATION

针对石油企业的组织结构越来越复杂,往下分层也越来越细,要求开发规划的指标也越来越多,以前的单层规划优化模型在应用上就存在很大的局限性,甚至已经不能满足油田开发规划要求的生产实际。将二层规划模型应用在油田开发规划中,建立了上、下产量最大,上、下效益最好,上层投资最低、下层成本最低的产量构成二层优化模型。这些模型成功地解决了油田各分项产量(通常含自然产量、措施产量、新区新井产量、老区新井产量)与对应的各项工作量及其它开发指标的最优构成问题。将模型应用于国内多个中、后期油田的开发规划中,产生了很好的经济效益。

With the development of the oil industry,the organizational structures of the petroleum corporations are more complex,their delamination is more and more fine,and the development programming target is more complex.So,the former monolayer optimal models have many constraints on application,and can not meet with the demand of oilfield development programming indeed.In this paper,the in-out conjunctional relationship of dynamic index of both oilfield and oil extraction plant is established.Furthermore,the bi-level programming model to oilfield development,and the optimal bi-level models of oil production composition for different goals including the maximum oil production are firstly applied,the minimum cost and the maximum economic benefit in both layers are established.These models can be used to solve the problems about the optimal compositions for each subentry oil production,usually including natural production,measure production,oil production of new well in new blocks,oil production of new well in old blocks,and the corresponding workload and other development indexes of oilfield or oil production plant.The satisfactory economic benefit can be obtained in the application of the models to the development programming in several oilfields in the mid-late stage.
