在此基础上提出了用不稳定试井资料确定气井产能的新方法，即用压力恢复曲线法与压降曲线法相结合确定气井产能的新方法。
Based on these, the new method that pressure build-up curve associated with pressure fall-off curve to determining the productivity of gas well is proposed.
实验结果表明，从注入压力-时间曲线上可以量出稳定的初破裂压力、重张压力、封闭压力。
The results of experiment show that: We can measurement stable first fracturing pressure, again open pressure, and close pressure.
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。
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.
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。
Unsteady testing for oil and gas well includes testing of drawdown curve and build-up curve.
对于定压边界，当时间趋向于无穷大时，气井产量与井底压力关系曲线即是我们常用的IPR曲线（不妨称为常规IPR曲线或稳定IPR曲线）。
Under the conditions of constant pressure boundary, when the time approaches to infinity, the curve between the flow rate and the bottom hole pressure is so called conventional IPR curve.
