节点分析技术在温米油田的应用

Application of Nodal Analysis Technique in Wenmi Oilfield

油田进入中高含水期后,提高油井产量的手段不仅仅停留在储层改造方面,还应充分挖掘井筒潜力,尽可能维持合理井底流压值进行开采。合理井底流压的确定采用节点分析技术,并以此为基础,建立一套科学的井底流压计算模型,确定单井合理井底流压,优化生产系统。

After stepping into medium and high water cut period, the measures improving production of oil wells in Wenmi oilfleld are more than reservoir reconstructions, but to fully develop the potential of weLlbore and maintain reasonable bottom - hole flowing pressure as possible to produce. Nodal analysis technique is used to determine reasonable bottom - hole flowing pressure, and based on the technique, a set of scientific calculation model for flowing pressure at the bottom of the hole are established to finally determine reasonable bottom - hole flowing pressure and current producing flowing pressure of the individual well,so as to optimize production system.
