Basing on Arps rate decline law and combining the material balance equation with the pseudo steady-state deliverability equation, Fetkovich and Fraim et al established a suit of type-curve matching of gas-well (oil-well)rate decline, which can determine the formation parameters.
Fetkovich和Fraim等人在Arps提出的产量递减规律的基础上,结合物质平衡方程和拟稳态油气井产能方程,建立了一套油气井产量递减的图版拟合方法,该方法可以反求地层参数。
