摘　　要：假设水和气互不相溶且相渗曲线符合幂指数规律,借鉴甲型水驱特征曲线关系式的研究方法,引入混相程度因子m,推导水气交替驱特征曲线关系式,建立水气交替驱开发动态指标评价和预测方法。最后,通过两个水气交替驱油田实例应用,结果表明,该方法能实现对水气交替驱油藏生产动态的快速预测。The method of performance evaluation and prediction of WAG was established by introducing new conception of mixed factor m.The equation was derived from type A water-drive characteristic curves by assuming that gas and water were immiscible each other and relative permeability curve was in line with exponential law.The method for evaluating and predicting the dynamic indexes of WAG was established.The WAG application in two reservoirs shows that the method can achieve the fast prediction of WAG performance.
