摘　　要：针对苏里格气田生产井压裂后,影响气井的产能因素,研究了测试时间、测试回压和储层渗透率非均质对气井产能的影响。结果表明,要想获得可靠的气井绝对无阻流量,必须保证足够长的测试时间;随着测试回压的降低,计算所产生的误差减小;井外圈半径越大,无阻流量越小,对产能影响程度越大;当井外圈半径一定时,变差程度越大,无阻流量越低,对产能影响越严重。这类问题的解决具有实际意义,能够直接指导油田生产。To factors affecting productivity of producing gas wells after fracture in Sulige gas field,influence of testing time,measuring pressure and formation inhomogenous permeability on productivity of gas well has been researched.Result shows that enough testing time is needed for acquiring QAOF in gas well,the error of calculating QAOF is decreased while measuring pressure declined,the outside radius gets more great when QAOF gets little;while the outside radius is constant,variation extent gets more great when QAOF gets little,which influences productivity serious.To solve these problems has actual sense which can guide production of oilfield directly.
