| 摘 要： | 在矿场的实际生产过程中，由于各种因素的影响，特别是在低渗透气藏时很难满足稳定试井的条件，求出的气井产能方程不能准确计算无阻流量。针对此类情况，提出了一种在不关井的情况下，求取气井二项武产能方程的改进方法，不需要开井生产前的地层压力，只需几组开井不稳定生产时的产量和流压，就能求出气井的产能方程和无阻流量。通过矿场实践表明，该方法具有一定的实用价值。

| Abstract: | In the practical production process, influence of some uncertain factors is hard to feed the need of steady test condition which makes the calculation of it's AOF become impossible. To this situation, an developed method for analyzing production of gas well is suggested which is under unclosing well condition, need not formation pressure data before opening well, only needs producing rate and flowing pressure of several units of opening wells. The field practice has showed that the new method is practicable... |
