Estahlishmeut and application of inflow performance relationship with an inflection point
摘要
Abstract
Dissolved gas will come out from oil in producing process when flowing pressure is lower than bubble point pressure, thus appeared three - phase flow in oil wells of water flooding reservoir, and oil production will decrease with the drop of flowing pressure , showing inversion of IPR curve. A newly established inflow performance relationship can reasonably match and describe the inversion, judge whether there will be an inversion or inflection point on IPR curve, and calculate the minimum reasonable flowing pressure in oil wells. The new IPR involves most of the classical IPR equations, such as Vogel and Fetkovich equations and their generalization formula, so it is highly practical.关键词
