Shallow layer drilling plug pressurization anti-jacking device and operation method

The invention relates to the technical field of underground workover treatment, in particular to a superficial layer drilling plug pressurization anti-jacking device and an operation method. Comprising an upper tray, a lower tray and a plurality of hydraulic cylinders arranged between the upper tray and the lower tray, oil pipe holes are formed in the upper tray and the lower tray, a movable pipe clamping device and a pipe clamping device driving assembly are arranged above the oil pipe hole in the upper tray, a fixed pipe clamping device is arranged above the oil pipe hole in the lower tray, and a flange plate used for being connected with a wellhead blowout preventer is arranged below the fixed pipe clamping device. Shallow layer plug drilling construction and rapid well shut-in can be completed conveniently, efficiently and safely, the problem that pressure cannot be applied to well mouth plug drilling is solved, the operation time efficiency is effectively improved, and blowout accidents are controlled. 本
