摘　　要：针对圆形封闭双层油藏,利用Laplace变换进行求解,给出Laplace平面上压力解的表达式。利用产量与压力的关系,重新定义了无因次变量,导出了新型产量的标准曲线。利用Laplace变换的数值反演方法给出了实空间的解,并将本结果扩展应用到多层油藏和气藏。In accordance with circular sealed dual-zone reservoir,Laplace algorithm is used to derive an expression of areal pressure.The dimensionless variable is redefined,and new standard curve of production is derived.The solution of real space is obtained by using the numerical inversion of Laplace algorithm.The result is extensively applied to multilayer oil reservoirs and gas reservoirs.
