Because the main drive mechanism is bottom water drive and the effects of lateral boundaries are negligible, it is assumed the gas reservoir is infinite with an impermeable upper boundary and a constant pressure lower boundary, without losing generality.

由于底水气藏的产气主要由底水驱动而得，侧边边界影响可忽略，故假定气藏由上边界封闭和下边界定压的无限大区域所导出的产能公式便具有普遍意义。
