由Vogcl提供的溶气驱井的无因次IPR曲线,是预测油井产能的非常重要的工具。目前,Vogel方程已被推广到未饱和油藏和水驱油藏的产水油井。但是,Vogcl方程仅只适用于理想井(即没有正的或负的表皮系数)和开采初期的条件。 The dimensionless IPR curve of a dissolved gas drive provided by Vogcl is a very important tool for predicting well productivity. At present, the Vogel equation has been extended to oil-producing wells in unsaturated and water-flooded reservoirs. However, the Vogcl equation applies only to ideal wells (ie, no positive or negative skin factor) and initial conditions of production.
