为了经济有效的满足日益增长的天然气需求量，提出一套对某地区凝析气藏群实施整体优化配产的新方法．根据运筹学的某种方法——线性规划，剖析了决策变量、目标函数及约束条件．以最小的成本为目标，建立起凝析气藏群开发动态规划数学模型：①凝析气藏群至各用气城市的输气路径规划模型；②凝析气藏群产气量规划模型，并采用Matlab软件进行了求解．在理论研究的基础上，以某盆地凝析气藏群2017-2020年作为实例计算，求解了该盆地凝析气藏群至各用气城市的最短路径，以及凝析气藏群规划的产气量．结果表明，此盆地凝析气藏群规划的产气量满足用气城市天然气的需求量．结论认为，该凝析气藏群开发动态规划模型保证了凝析气藏群产气量的准确性且精度更高，为决策者对凝析气藏群的宏观管理提供定量依据．

In order to effectively meet the increasing demand for natural gas, this paper presents a set of new methods for integrated optimization of production allocation for condensate gas reservoir group in some areas. According to a method of operational research--linear programming, the decision variables, objective functions and constraints are analyzed. Being aim at cost maximization, We build up a mathematical model of dynamic programming of condensate gas reservoir group. One is programming models of each path from condensate gas reservoir group to cities of using gas, and the other is programming models of the amount production of condensate gas reservoir group by using software programming of Matlab to solve. Based on a theoretical research, take the condensate gas reservoirs in some basin as an example： to obtain the shortest path from condensate gas reservoirs to cities using gas and the dynamic programming of condensate gas reservoirs from 2017 to 2020. The results show that the amount of programming production of natural gas in condensate gas reservoirs meet the demand of gas in gas cities in this basin. In this way, this model guarantees the accuracy and accuracy of gas production of condensate gas reservoir group, and the quantitative reference of macro-management on condensate gas reservoir is offered to some deciders.
