特高含水期新型水驱特征曲线
New water drive characteristic curves at ultra-high water cut stage
摘要
Abstract
A function expression of the oil-water relative permeability ratio with normalized water saturation at high water saturation was proposed based on statistics of measured oil-water relative permeability data in oilfields.This expression fits the later section of conventional relative permeability ratio curve more accurately.Two new water drive characteristic curves at the ultra-high water cut stage (fw＞90％) were derived by combining the new oil-water relative permeability ratio expression and reservoir engineering method.Then,the numerical simulation results of five point well pattern and production data of Yangerzhuang Oilfield and Liuzan Oilfield were used to verify the adaptability of the new water drive characteristic curves.The results showed that the new water drive characteristic curves are more accurate than conventional water drive characteristic curves after A type and B type water drive curves rise,and can be used to predict production performance at ultra-high water cut stage,ultimate recovery efficiency and recoverable reserves.关键词
