基于粒子群算法原油集输管网优化

随着油田开发进入中后期不断进行井网加密，如何在最大化合理利用已建联合站年处理能力的基础上，尽可能减少投资管网建设，实现新建的计量间和联合站之间原油集输管网的合理分配，寻求以管网造价最小为目标函数，以联合站的最大年处理能力、集输半径和连接方式为约束条件，建立单目标优化模型。根据粒子群算法寻优特点，结合十进制编码，通过适应度函数评价，实现该模型的优化求解。采用遗传算法和粒子群算法分别对某一星状原油集输管网优化问题进行计算对比，结果表明，粒子群算法计算更为简洁，收敛速度也较优，有利于提高集输站利用效率．

Optimization of Crude Oil Gathering Network Based on Particle Swarm Algorithm

With the infilling of well pattern again and again in the latter stage of oilfield development,it became a concern to minimize investment in pipe network construction,and reasonably allocate the gathering network between the newly-built metering room and central treating station on the basis of the rational utilization of the annual processing capacity of the current central treating station.The single-objective optimization model taking the minimum network cost as objective function,and maximum annual proc...
