Abstract
The utility model discloses a split self-sealing well sealer used in oilfield well repair. The well sealer consists of bolts, blind flanges, steel rings, a left seal body, an oil pipe, a right seal body, steel body frames and cross joints. The left seal body and the right seal body are half-revolution bodies, and are clasped into a full-revolution body and arranged in the cross joints; and the blind flanges are arranged on the left seal body and the right seal body and fixed on the cross joints by the bolts, and each blind flange is provided with an open slot. The steel body frames are arranged in the left seal body and the right seal body. The upper end face of each of the left seal body and the right seal body is provided with a concave ring groove, each corresponding blind flange is provided with a convex ring, and the convex rings on the blind flanges are embedded into the concave ring grooves in the upper end faces of the left seal body and the right seal body. A steel ring is arranged between the left seal body and the cross joint, and a steel ring is arranged between the right seal body and the cross joint. The left seal body and the right seal body are the half-revolution bodies, the left seal body and the right seal body can be clasped on an oil pipe from the outer surface of the oil pipe during installation and are not required to penetrate through the head of the oil pipe, and the oil pipe is not required to be reversed, so that time and labor are saved; and the well sealer is easily detached when blowout happens, and can play a role in centralizing the oil pipe, preventing ground objects from falling into a well and preventing oil dirt on the outer wall of the oil pipe from being brought to the ground to pollute the environment.
Description
Technical field
The utility model belongs to the mechanical device that the oil field well workover is used, and is a kind of split type from blowout preventer.
Background technology
The oil field when workover treatment, with the OIH pipe from ground G.I.H, also to the OIH pipe be put to ground from tripping out in the well, fall in the well in order to prevent ground object; Prevent that oil-pipe external wall greasy dirt field to ground from causing environment pollution, also will set upright oil pipe simultaneously, generally will install from blowout preventer at well head, present is one from blowout preventer; Be the revolution bodily form, oil pipe passes internally, because the OIH pipe is successional; Pipe elevator is arranged at the oil pipe top, oil pipe is penetrated in blowout preventer very trouble, fall oil pipe; Waste time and energy, when the generation blowout is speedily carried out rescue work, be not easy to remove blowout hookup is installed from blowout preventer.
Summary of the invention
The purpose of the utility model is that design is a kind of split type from blowout preventer, makes it easy for installation, need not fall oil pipe, and is time saving and energy saving, is easy to when blowout takes place remove.
The purpose of the utility model is achieved in that and comprises bolt, blind flange, left sealed body, oil pipe, right sealed body, skeleton, big four, and left sealed body, right sealed body are half revolving body, and embracing is a whole revolving body; And be installed in the big four; Blind flange is installed in left sealed body, right sealed body upper surface, and by being bolted on the big four, blind flange is provided with open slot; Steel body skeleton is arranged in left sealed body, the right sealed body; There is concave ring groove left sealed body, right sealed body upper surface, on the corresponding blind flange bulge loop are arranged, and the bulge loop on the blind flange embeds in the concave ring groove of left sealed body, right sealed body upper surface.
Between left sealed body, right sealed body and the big four steel ring is arranged.
The beneficial effect of the utility model is: left sealed body, right sealed body are half rotary structure, can embrace on oil pipe from the oil pipe external surface during installation, need not penetrate from tubing head; Need not fall oil pipe; Time saving and energy saving, when taking place, blowout is easy to remove, and can play and set upright oil pipe; Prevent that ground object from falling in the well, prevent that oil-pipe external wall greasy dirt field to ground from causing environment pollution.

Fig. 1 is the assembling drawing of the utility model.
Fig. 2 is the vertical view of blind flange 2 among Fig. 1.
The specific embodiment
Embodiment below in conjunction with Fig. 1,2 pairs of the utility model describes.
Can know by figure; The embodiment of the utility model comprises bolt 1, blind flange 2, steel ring 3, left sealed body 4, oil pipe 5, right sealed body 6, steel body skeleton 7, big four 8, and left sealed body 4, right sealed body 6 are half revolving body, and embracing is a whole revolving body; And be installed in the big four 8; Blind flange 2 is installed in left sealed body 4, right sealed body 6 upper surfaces, and is fixed on the big four 8 by bolt 1, and blind flange 2 is provided with open slot 9.Steel body skeleton 7 is arranged in left sealed body 4, the right sealed body 6.There is concave ring groove left sealed body 4, right sealed body 6 upper surfaces, on the corresponding blind flange 2 bulge loop are arranged, and the bulge loop on the blind flange embeds in the concave ring groove of left sealed body 4, right sealed body 6 upper surfaces.Between left sealed body 4, right sealed body 6 and the big four 8 steel ring 3 is arranged.
During installation, left sealed body 4, right sealed body 6 synthetic integral body are inserted in the big four 8 after being buckled on the oil pipe 5, the open slot of blind flange 2 is aimed at and is buckled on left sealed body 4, the right sealed body 6 after oil pipe gets into; Erection bolt 1 makes the utility model be connected into one, when oil pipe 5 up-downgoings; Greasy dirt, silt on oil pipe 5 walls are drawn together down, and greasy dirt can not taken ground out of, and silt can not fall in the well; When left sealed body 4, right sealed body 6 were passed through in tubing coupling, it passed through under the caoutchouc elasticity effect, can to become ambassador.
