摘要
介绍了一种新的对未来不同开发时期IPR曲线的制作方法。该方法考虑地层压力采用物质平衡方程得到;通过应力敏感试验结果拟合得到地层渗透率随地层压力变化关系,以相渗曲线为基础得到产液含水率随采出程度的变化关系,进而确定出不同开采时间的产液含水率,在已知地层压力、采液指数、含水率条件下采用Petrobras综合IPR方法确定油井的IPR。
A new method of inflow performance relationship(IPR) curves for different development stages in the future is introduced.The method is derived by using material balance equation in combination with formation pressure.The correlation of permeability changing with formation pressure is obtained by simulating the result of stress sensitive test.The correlation of water content ratio of produced fluid changing with recovery percent is obtained based phase permeability,consequently the water content ratios in different production periods are determined.Under the conditions of known formation pressure,liquid producing coefficient and water content ratios,an integral Petrobras IPR method is used to establish IPR of oil wells.
