The utility model provides a blowout preventer shear ram based on shaped charge blasting cutting. The utility model belongs to key equipment for drilling control in the field of ocean engineering. Theblowout preventer shear ram is applied to a well control device for offshore oil drilling and workover. The flashboard mainly comprises a flashboard shell, an energy-gathering cover, explosives, a waterproof protective layer, a fastener and an energy-gathering device shell, the flashboard is installed in the blowout preventer, when a drill rod needs to be sheared in an emergency, the blowout preventer hydraulically acts to push the flashboard to tightly hold a drilling tool, at the moment, the energy gathering cover is tightly pressed on the surface of the drilling tool, explosives are detonated, the energy gathering cover is pressed by instant high pressure generated by explosion of the explosives to generate metal jet flow, the drilling tool is cut off, and then the fully-sealed blowoutpreventer is closed.
