中文摘要:
      流入动态曲线(IPR曲线)是分析油井生产状态的基础,也是确定油井合理工作制度的依据。常规的油井流入动态模型不能用于分析聚合物驱油井的流入动态关系,为此,学者们建立了不同的聚驱油井流入动态模型。但这些模型的求解普遍较为复杂,不便于现场应用。本文通过无因次化处理得到了聚驱油井的无因次流入动态方程。以数值模拟技术为手段,研究了不同地质油藏条件、不同流体性质和不同聚合物溶液性质的聚驱油藏的油井流入动态状况,仿照Vogel处理溶解气驱油藏无因次IPR曲线的方法进行非线性拟合回归,得到了便于现场应用的无因次流入动态方程。实例计算结果验证了方程的可靠性,可用来计算油井的流入动态,能够为聚驱油藏油井的生产动态分析和合理工作制度制定提供参考。
英文摘要:
      The inflow performance relationship curve (IPR curve) of oil wells is the basis for analyzing the production performance and determining the reasonable working mode of the wells. The conventional oil well inflow performance model cannot be used to analyze the inflow performance relationship of polymer flooding wells. For this reason, scholars have established different inflow performance models for polymer flooding wells. However, it is generally complicated to solve these models, and they are not convenient for field applications. In this paper, the dimensionless inflow performance equation of polymer flooding wells was obtained by dimensionless treatment. Using numerical simulation techniques, the inflow performance of polymer flooding reservoirs with different geological reservoir conditions, different fluid properties and different polymer solution properties was studied. Non-linear fitting regression was performed by following Vogel"s method of treating the dimensionless IPR curve of dissolved gas flooding reservoirs. The dimensionless inflow performance equation easy for field applications was obtained. The calculation results of the example verified the reliability of the equation. The equation can be used to calculate the inflow performance, and provide reference for the production performance analysis and the determination of rational work system of oil wells in polymer flooding reservoirs.
