Abstract
The utility model discloses a high-pressure efficient fracture well head device. The fracture well head device comprises a bottom valve (1), a fracture head (3), flutter valves (4), union flanges (5), an overhead valve (6) and a Christmas tree cap flange (7). The overhead valve (6) and the bottom valve (1) are sealed through steel rings (2) and connected to the top and the bottom of the fracture head (3) through bolts and nuts respectively, one ends of the four flutter valves (4) are connected to the four side faces of the fracture head (3) respectively, the flange positions of the other ends of the flutter valves (4) are connected with the union flanges (5), the Christmas tree cap flange (7) is connected to the top of the overhead valve (1), and the whole constitutes the fracture well head device. The high-pressure efficient fracture well head device is simple in structure and easy to operate, solves the problem that an oilfield which is low in output, permeability and porosity is very difficult to exploit, and particularly provides more effective measures for exploitation of shale gas.
