摘要
在研究油田生产系统的各种流动形态的基础上,采用节点分析的方法,把油田生产系统分为5个相对独立的子系统,节点为2个相邻子系统的连接点,传递的是流量和压力2个动态参数.根据注采平衡原理,确定了每个子系统中的能量损耗,建立了生产系统地面管网能耗分析的理论模型;以大庆杏六联地区能耗分析为例,提出了整体优化的方法.结果表明:建立的能耗模型能够很好地表示该地区生产系统的能耗;油层渗流在整个生产系统中的能耗比例最大,为40.2%;可进行压裂措施优选提高油层的渗流能力,改造污水处理工艺,改善油水井的完善程度.
Based on the research of different floating forms in injection system and recovery system,the paper introduces nodal analysis method to divide oilfield production system into five subsystems.Node is the connection point of the adjacent subsystems.And the two dynamic parameters,flux and pressure,are transferred by the node.According to the theory that the injection and the recovery is an equation,the energy loss of every subsystem is ascertained,the energy loss analysis theoretical model of production system ground pipe network is established,the energy loss is analyzed and the global optimization method of Daqing Xingliulian plot is proposed.Results show that the established model can well express the energy loss of production system,the energy loss of percolation in oil layer is the most,it is 40.2 percent of all energy loss,treatment of fracturing can improve the capability of seepage flow and changing the technics of effluent treatment can improve the perfect degree of water wells and oil wells.
