Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to shown in Fig. 1, a kind of high-efficiency blowout prevention device for oil exploitation, control including housing 5, support tube 8, driller
It is provided with piston 4 inside platform 13, remote console 15, and housing 5；Described piston 4 top is provided with support circle 3, and supports circle 3 sides
Small sealing ring 2 is set；Described housing 5 top arranges top cover 7, and top cover 7 inside is provided with fixing bolt 1；Set bottom described top cover 7
There is support tube 8, and support tube 8 outside is provided with Fructus Cucurbitae moschatae pectin core 9；Described Fructus Cucurbitae moschatae pectin core 9 side arranges large sealing packing ring 10；Described support
Cylinder 8 sidewalls arrange flashboard 6, and flashboard 6 connection has lock shaft 11；It is provided with gasket ring 12 bottom described housing 5, and housing 5 outside connects
