摘要
利用6种类型IPR方程,对文献油藏模拟器生成数据进行了重新拟合,得出了不同IPR方程在不同井斜角下的Vogel参数值。数值分析结果为:Winggins-Rissell-Jennings方程拟合精度最好,Klins-Majcher方程次之,Vogel方程较差,Fetkovich方程、Harrison方程和Bendakhlia-Aziz方程最差。这表明Winggins-Russell-Jennings方程和Klins-Majcher方程比Vogel方程更适用于描述不同井斜角下的IPR方程,而Fetkovich方程、Harrison方程和Bendakhlia-Aziz方程的适应性相对较差。
By using six Kinds of IPR equation, the data generated by reservoir simulator mentioned in literature has been matched again, which provides the Vogel parameters value of different inclinations in different IPR equations. The numerical value analysis result follows as： Winggins - Russell - Jennings equation is the best in matching precision, Klins- Majcher equation takes the second place in matching, Vogel equation is worse, and Fetkovich, Harrison and Bendakhlia - Aziz equation the worst in matching. It indicates Winggins - Russell - Jennings and Klins- Majcher equation are more fit for describing the IPR equation of different inclination than Vogel equation, and the applicability of Fetkovich, Harrison and Bendakhlia - Aziz equation is worse.
