| 摘 要： | 本文在总结国内外现有节点分析技术的基础上，建立了特低渗油田抽油井节点分析的数学模型，除应用比较成熟的计算公式外，还通过悬点负荷及古德曼应力图提出了适合特低渗油田抽油井泵口压力计算的新公式．软件用ＢＡＳＩＣ语言编制，经安塞油田王窑区９７口井的应用证明，所用数学模型基本符合特低渗油田的实际，应用这套软件不仅可以为特低渗油田抽油井工艺参数的优化和增产措施提供科学依据，而且对于提高特低渗油田开发效果和管理水平具有积极的作用．

| Abstract: | Based on summing the existing nodal analysis technology,this paper establishes appropriate mathmatic models of nodal analysis of pumping wells for extremly low permeable oilfield(ELPO).Besides using maturer formulas,new formula that is used to calculate pump intake pressures for ELPO is presented through the loads of point of support and Goodman stress diagram.The software is worked out with BASIC language.Through the application in 97 wells of Ausal oilfield,it shows that the used mathmatic models are in basic accordance with practice. It not only provides scientific basis for parameters the optimization and well stimulation pumping well,but also has positive roles for improving the development results and raising management level. |
