摘　　要：根据抽汲井开采工艺特点,建立了圆形封闭复合地层中心抽汲井数学模型,通过块中心网格和隐式差分格式对定解问题离散后求出了数值解。用该模型对克拉玛依油田M13井进行解释,其结果表明该模型可以较好地反映井底压力复杂的变化过程,并能较准确地解释复合油藏抽汲井生产的非自喷井流动期或恢复期的测试资料。Based on the characteristics of the practical production features of swabbing wells,a mathematical model was established based on a swabbing well in the circular sealed composite reservoir center,while the central block grid was constructed,the numerical solution was obtained when Definite Solution Problems was scattered by using implicit scheme.The model is used to explain the Well M13 in Karamay Oilfield,the result shows that the method is high precision to reflect complicated changing process of bottom hole pressure,and it can be used to interpret flowing test data and buildup test data of nonflow wells of composite system accurately.
