基于BFS算法的油田污水系统参数计算方法研究

Study on Parameter Calculation Method of Oilfield Sewage System Based on BFS Algorithm

油田污水系统作为一个结构连通性相对复杂的流体网络,目前尚未有适当的方法对其内部水力参数进行计算分析。以环枝状污水管网结构为研究对象,结合污水系统连续性方程、能量单元方程,建立了污水系统参数分析计算数学模型,融合"图论思想",基于广度优先搜索(BFS)形成了油田污水系统参数计算分析方法。并以此开发了油田污水系统参数计算分析系统,对现行污水系统进行参数计算。分析结果表明,此计算方法能高效求解污水管网结构的水力参数,在完全满足工程计算要求的同时,亦可为后续生产运行提供理论分析基础和相应的数据支持。

There is no proper method to calculate and analyze the internal hydraulic parameters of oilfield sewage system as a fluid network with relatively complex structure connectivity.In this paper,taking the ring branch sewage pipe network structure as the research object,combined with the sewage system continuity equation and energy unit equation,the mathematical model of sewage system parameter analysis and calculation was established,and the parameter calculation and analysis method of oilfield sewage system was formed based on the breadth first search(BFS)and the"graph theory"idea.Based on this,the parameter calculation and analysis system of oilfield sewage system was developed.The analysis results showed that this method could solve the hydraulic parameters of the sewage pipe network structure efficiently,fully meet the engineering calculation requirements,and also provide theoretical basis and data support for the subsequent production and operation.
