Abstract
The utility model relates to an oilfield wellhead sealing device, in particular to an oil well cable sealer on a wellhead. The oil well cable sealer has the technical proposal that a cable pore channel is arranged on the main body of a hanger, a sealing gasket is installed at the most outer end of the cable pore channel, and a pressure plate is fixed at the outside of the sealing gasket by a bolt. A plurality of cable pores are arranged in the middle of the pressure plate, and a plurality of cables penetrate through the cable pores. The top of the cable pore channel is in the shape of a cone. The sealing gasket is in a fission structure with a plurality of cable pores, and is matched with the cone of the cable pore channel. The oil well cable sealer on the wellhead has the beneficial effects that the sealing gasket expands and shrinks by the action of the pressure plate, thereby reaching complete sealing of a cable channel, and enhancing the sealing effect.
Description
One, technical field:
The utility model relates to a kind of oil field shaft mouth sealing device, particularly the oil well cable seal device on the well head.
Two, background technology:
The electric pump hanger is the important sealing device on the electric pump producing well well head, the cable of oil extraction pump is guided on the power distribution equipment of ground passing hanger between oil pipe and the sleeve pipe, in the well very big pressure is arranged when oil recovery or well-flushing, and present hanger sealing device is with the dull and stereotyped extruding of two perforated metal perforated flat plate oil-resistant rubber slab, distortion tension by rubber tile seals, the problem of its existence is: when borehole pressure increases, just along gap between cable duct pressing plate and the main body and the clearance leakage between the rubber pad and the outside diameter of cable, sealing effectiveness is poor for liquid between oil pipe and sleeve pipe.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and the oil well cable seal device of sealing effectiveness also can be provided when providing a kind of pressure to increase.
Its technical scheme is: be provided with the cable duct on hanger body, outermost end in the cable duct is equipped with sealing mat, sealing mat is outer to have pressing plate by bolt, be provided with a plurality of cable aperture in the middle of the pressing plate, many cables therefrom pass, the top in described cable duct is cone shape, and described sealing mat is the branch body structure that has a plurality of cable aperture, and matches with the cone in cable duct.
The both sides of the pressing plate of described bolt one side are provided with groove.
The beneficial effects of the utility model are: sealing mat is expanding and contraction under the effect of pressing plate, thereby has reached the sealing fully of cable passage, has improved sealing effectiveness.
Four, description of drawings:
Accompanying drawing 1 is a sectional view of the present utility model;
Accompanying drawing 2 is vertical views of sealing mat of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
Its technical scheme is: be provided with cable duct 2 on hanger body 1, outermost end in cable duct 2 is equipped with sealing mat 3, be fixed with pressing plate 4 by bolt 6 outside the sealing mat 3, be provided with a plurality of cable aperture in the middle of the pressing plate 4, many cables 5 therefrom pass, the top in described cable duct 2 is cone shape, and described sealing mat 3 is the branch body structure that has a plurality of cable aperture, and matches with the cone in cable duct 2.The both sides of the pressing plate 4 of described bolt 6 one sides are provided with groove 7, are convenient to take out pressing plate 4.
Use is: rotatably compress sealing mat 3 by screwing bolt 6 during installation, sealing mat 3 is outwards expanding and inwardly contraction under strong pressure, has realized the sealing in cable duct; During maintenance, screw off screw bolt 6 after, take off pressing plate from pressing plate 4 two ends grooves 7, alleviated labour intensity, improved operating efficiency.
