Beschreibung
Zusammenfassung:	The invention relates to a pilot-controlled hydraulic blowout preventer control device and application. The device comprises an energy accumulator group, a driller console, a high-pressure control area and a normal-pressure control area, the high-pressure control area comprises a high-pressure regulating valve, a high-pressure two-position three-way rotary valve, a first air cylinder, a high-pressure shear valve, a second air cylinder and a high-pressure reducing valve; a liquid inlet of the high-pressure two-position three-way rotary valve is connected with an energy accumulator group through a high-pressure pressure regulating valve; a first liquid outlet of the high-pressure two-position three-way rotary valve is connected with the normal-pressure control area through a high-pressure reducing valve; a second liquid outlet of the high-pressure two-position three-way rotary valve is connected with a liquid inlet of the high-pressure shear valve; the first air cylinder is connected with the high-pressure two-
