摘　　要：综合考虑利润、产量、吨油成本和投资等目标,建立了三元复合驱模糊多目标最优控制模型。该模型以三元驱替剂的驱油机理为支配方程,以驱替剂的浓度和用量限制为约束条件,以驱替剂的注入浓度为优化变量。对于该模糊多目标最优控制问题,首先引入隶属度函数,将每个目标进行确定性描述,然后借鉴对称模型的思想,提出了一种模糊多目标处理方法。引入权值将各个性能指标根据设定的侧重程度映射到统一的对称集合中,选取其中一个目标作为模糊目标集,其余的作为模糊约束集,采用λ水平截集迭代法将该模糊多目标规划问题转化为确定性单目标问题。采用混合螺旋优化算法进行求解,得到三元复合驱的最优注采策略。最后通过仿真分析验证了提出算法的有效性。With comprehensive consideration of the objectives for profit,outcome,ton oil cost and investment,a fuzzy multi-objective optimal control model of alkali-surfactant-polymer(ASP)flooding is constructed.In the model,the oil-displacement mechanism of three displacing agents is used as the governing equation,the limits of concentration and dosage for displacing agents are used as the constraints,and the injection concentration of displacing agents is the optimization variable.Aiming at the problem of optimal control for the fuzzy multi-objectives,a fuzzy multi-objective process method is developed,in which the subordination function is introduced,and each objective is described with determinacy,and the symmetry model is referenced.Every performance objective is mapped into a unified symmetry set according to its importance with introduced weight.One objective of the set is selected as the fuzzy objective set and the others as the fuzzy constraint set.The fuzzy multi-objectives programming problem is converted into a deterministic single objective problem with introduction ofλlevel cut set iteration method.The hybrid spiral optimization algorithm is applied to solve to get the SAP flooding optimal injection strategy.The effectiveness of proposed method is verified through simulation analysis.
