Relative permeability curve method and stream-tube method are commonly used to plot theoretical curves of water-cut vs. recovery percent of reserves.

制作含水率与采出程度关系理论曲线常采用相渗曲线法和流管法两种方法。

In general, when recovery percent of reserves is lager than 50 percent at latter stage, the relation between cumulative oil and cumulative produced gas oil ratio is linear.

通常，对于可采储量采出程度大于5 0 %开发到中后期的油藏，累积产油量与累积生产气油比之间一般存在线形关系。
