五站气田是一个浅层低产低丰度小型气田，属断层发育。随着气田的开发进程，气田各气井均不同程度地出水，形成了积水压迫气层或在井筒及外输管线中形成水合物而堵塞通道，造成减产甚至停产。要保证气井正常生产，就必须采取排排液，化解水合物等一系列处理措施。由于气田的开采工艺、设备配置、生产制度要求及人员配备等条件决定了五站气田每班（１５天）的工程处理能力为１５井次，不能完全满足气田需要。应合理分配工程处理量，使得五站气田期望日产气量下降值最少。应用离散确定性动态规划模型对五站气田工程处理能力进行优化分配，充分利用有效资源，减少设备与物资的无效消耗，科学调整气田管理工作制度。
The Wuzhan gas field is a shallow, low-yield, low-abundance, small gas field with a fault development. With the development of the gas field, all gas wells in the gas field are discharged with different degrees of water, resulting in the formation of water pressure reservoirs or the formation of hydrates in the wellbore and the transmission pipeline to block the passage, resulting in the reduction of production or even the shutdown of production. To ensure the normal production of gas wells, we must take a row of liquid, to resolve hydrate and a series of treatment measures. Due to the conditions of gas field mining technology, equipment configuration, production system requirements and staffing, the project processing capacity of each station (15 days) in the Wuzhan gas field is 15 wells, which can not fully meet the needs of the gas field. The project throughput should be rationally allocated so that the descending value of daily output of gas in the five stations is expected to be the least. Discrete deterministic dynamic programming model is used to optimize the engineering treatment capacity of Wuzhan gas field, make full use of effective resources, reduce the inefficient consumption of equipment and materials and scientifically adjust the management system of gas field.
