摘要
本文对于考虑井筒储集效应和表皮效应情况下的双重渗透率问题进行了研究。利用Laplace-Weber双重积分变换严格进行求解,并用Weber反变换给出Laplace平面上压力的解析表达式。再利Laplace变换的数值反演方法,计算出压力及其导数随时间的变化系关。本文结果可用于双渗透地层的试井分析。
The double permeability reservoirs with skin and wellbore storage effects are studied by using Laplace-Weber dual integration transformations. The solutions of dimensionless bottom hole pressure in the Laplace plane are given by formula (28). Then the numerical inversion method of Laplace transform is applied to compute the pressure and its derivative. Figs. 2-5 present, on log-log scale and in dimensionless terms, part results of the pressure and its dire-vative with respect to the log of time for a well with skin and wellbore storage in double permeability reservoirs.
