摘　　要：采用高温高压气体渗透率仪,模拟气层岩石就地应力条件下,测试不同流速下气体渗透率的变化情况,找出气测渗透率的敏感值及速敏临界流量。运用渗流力学原理,计算气井临界流量,为气井的配产提供依据。Through measuring the reservoir core permeability as the change of flowing velocity under formation stress by usng HPHT permeability instrument, find out the active point of gas permeability and the gas flowing sensitivity critical flow rate. Employing the seepage flowing theory calculate the critical flow rate of gas well and all these provid relative evidence for determining proration production of gas well.
