由于三次采油开发方式具有集中配制、分散注入的特点 ,所以聚合物配制站必须在空间和时间上对几个区块提供共享服务 ,以提高综合利用率 ,由此带来了聚合物配制站的优化布局问题。从数学规划和系统工程的角度出发 ,应用网络流规划方法建立了存储模型和选址模型混合的优化布局模型 ,编制了专用的大规模组合优化算法程序。该程序在给定各个区块生产时间和中转站布局的条件下 ,以投资最省为目的 ,优选出配制站个数、规模和位置 ,并绘出配制站与中转站的服务网络图。以聚合物驱油条件下大庆油田的萨中油田为规划对象进行了数值计算 ,与人工规划结果对比表明 ,该模型可节约投资 3%～ 5 % ,并能辅助三次采油规划人员进行优选配制站的方案布局。
Due to the centralized preparation and decentralized injection mode, the polymer preparation station must provide several services in space and time for several blocks to improve the comprehensive utilization rate, thus bringing the polymer preparation station Optimize layout issues. From the perspective of mathematical programming and system engineering, an optimized layout model of hybrid storage model and site selection model is established by using network flow planning method, and a special large-scale combined optimization algorithm program is prepared. Given the production time of each block and the layout of transfer stations, the program selects the number, size and location of the preparation stations for the purpose of the least investment and draws a service network diagram of the preparation stations and transfer stations. The numerical simulation of Sazhong Oilfield in Daqing Oilfield under the conditions of polymer flooding was carried out. Compared with the results of manual planning, this model can save 3% -5% of the investment, and can assist the tertiary oil recovery planners to make the optimal preparation station The layout of the program.
