原油集输网络系统优化软件的开发

认为集输系统实际上是一个由点集 (油井、计量站、转油站、脱水站 )和边集 (子站和母站间管线 )构成的树状网络 .原油集输网络系统优化的任务就是在给定油井位置 ,油产量的情况下 ,优选各种站的位置、个数、管辖范围和规模 ,以解决站的平面布局问题 .其约束条件是流量压力平衡和温度压力等满足工艺条件 ,目标是投资与运行费之和最小 .建立了优选站位置的数学模型 ,阐述了求解这个复杂的选址问题的一个启发式算法 ,讨论了优选管径和站内设备问题 ,给出了软件编制的部分框图和利用软件进行网络优化的实际算例 .该软件可以辅助地面系统规划人员进行优选管 -站的布局方案

Development of the Optimization Software of Crude Gathering and Transportation System

A crude gathering and transportation network system is a tree like network. It consists of some nodes (oil wells and stations) and lines (pipelines). The stations include measuring stations, transfer stations and dehydrating stations. The optimization of the system is to decide the optimal number, location, jurisdiction and scale of the stations, given the location of the wells and the oil production of every well. The optimization objective of the system is to minimize investment plus operating cost, and the constraints are the balance of flow rate and pressure, and temperature and pressure meeting the requirement of technological condition. The corresponding mathematical model was established. A heuristic algorithm were put forward, which is suitable to the complicated mathematical model. The corresponding software to the algorithm was also developed. Some examples show that the optimization model and the software are all feasible.
