1·Unsteady testing for oil and gas well includes testing of drawdown curve and build-up curve.

油井和气井的压力不稳定测试，包括压降曲线测试和压力恢复测试。

2·This theory has been proved by gas well test in field. According to the apparent steady state date in pressure drawdown curve, the control reserves of a gas well can be calculated correctly.

气藏现埸试验证实了该理论的正确性，并根据压力降落曲线中的视稳定状态资料，便能正确计算气井的控制储量。

3·The heat dissipation assessment of radiator needs both drawdown flow curve and heat exchange flow curve.

散热器散热能力的评估需要压降-流量曲线和换热量-流量曲线。

4·This paper discusses-the theory and method of deriving the single well Q-S(yield and drawdown) curve using coefficient of permeability from testing and other empirical parameters.

本文探讨了利用测试的渗透系数和其它经验参数推求单孔Q—S（出水量与水位下降）曲线的理论和方法。

5·We can find that there is apparent peak value on the flow curve, the driving pressure differential corresponding to the peak value is the feasible drawdown.

发现流量曲线存在明显的峰值，该峰值对应的驱动压差就是合理生产压差。
