Abstract: he coincident rate of electric log interpretation and gas test result in deep condensate reservoir of Qiaokou gas field was very low. In order to solve this problem, new gas layer interpratation standard suitable to Qiaokou area was built and a set of feasible chart was drawn through integrated study of 173 gas layers in 20 gas wells here. This new standard maked the coincidence rate increases by 44.4%, guided new broughtin wells and provided reference for other gas fields home and abroad.
