The invention provides a wellbore plugging removal method and device for a high pressure gas well. The plugging removal method comprises the following steps: injecting a working fluid into the wellbore for acidizing treatment; perforating the oil-passing pipe; and performing blowout treatment on the high pressure gas well. The invention can increase the oil drainage area through the perforation of the oil pipe on the basis of removing the plugging by the acid liquid, so as to realize the wellbore removal of the high pressure gas well with simplicity, safety, high efficiency and low cost. |
