The author proposes a method to interpret results of thermogasdynamic testing of vertical gas wells imperfect as far as the penetration degree of the stratum is concerned. A study is made of the influence of the parameters of the anisotropic stratum and the near-wellbore region on the curves of pressure and temperature at the wellbore. It is shown that when the penetration of the anisotropic stratum is incomplete, the parameters of the stratum and of the near-wellbore region can be assessed from the results of pressure and temperature measurements at the bore of the well after its startup.
