Abstract
The utility model discloses a shunting pressure reducer for an oil well blowout prevention box. The shunting pressure reducer comprises an oil extraction pipe plugging and shunting component and a connection guide pipe arranged on the oil extraction pipe plugging and shunting component, wherein the oil extraction pipe plugging and shunting component comprises plugging sheets, sealing pads and fixing sheets which are sequentially arranged and are fixed together through fasteners; and the connection guide pipe is fixedly connected with the fixing sheets. The shunting pressure reducer is simple in structure, rational in design, convenient to assemble and use and good in using effect; and liquid extracted from a well can be effectively shunted and decompressed, so that pressure of the liquid in the well on the blowout prevention box is reduced, the blowout prevention and leakage prevention effects are enhanced, and the environment pollution is reduced.
Description
Technical field
The utility model relates to a kind of decompressor, especially relates to a kind of oil well blowout prevention box shunting decompression device.
Background technology
At present, generally use the blowout prevention box, during use, the blowout prevention box is installed on the sucker rod of oil pumper for preventing the oil-well blowing phenomenon.In the aspiration procedure of oil pumper, the liquid in the well can come on the sucker rod outer wall belt, when the liquid that draws up is run into the blowout prevention box, under the effect of blowout prevention box, gets into three-way pipeline, and then is stored in the oil storage tank.
Because the pressure in the well reaches more than the 30MPa; Therefore it is bigger to the impact force of blowout prevention box to aspirate the liquid that comes up; So not only fragile blowout prevention box influences the blowout prevention effect of blowout prevention box, in case and the blowout prevention box damage; It is serious then to cause liquid to leak in blowout prevention box upper end, causes the waste of bigger environment pollution and liquid.
The utility model content
The utility model technical problem to be solved is to above-mentioned deficiency of the prior art; A kind of oil well blowout prevention box shunting decompression device is provided; It is simple in structure, reasonable in design and easy to install, result of use is good, can effectively make the liquid that draws up in the well obtain shunting release, thereby reduces the impact force of the interior liquid of well to the blowout prevention box; Improve the blowout prevention leak preventing effect, reduce environment pollution.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of oil well blowout prevention box shunting decompression device is characterized in that: comprise oil pick-up tube shutoff shunt assembly and be arranged on the connecting duct on the said oil pick-up tube shutoff shunt assembly; Said oil pick-up tube shutoff shunt assembly comprises shutoff sheet, gasket seal and the stator that sets gradually, and said shutoff sheet, gasket seal and stator are fixed together through securing member; Said connecting duct is fixedly connected with stator.
Above-mentioned oil well blowout prevention box shunting decompression device is characterized in that: have a plurality of pressure release return ports on the said connecting duct, a plurality of said pressure release return ports evenly are provided with.
Above-mentioned oil well blowout prevention box shunting decompression device, it is characterized in that: said securing member is a bolt.
Above-mentioned oil well blowout prevention box shunting decompression device, it is characterized in that: said gasket seal is the rubber pad.
Above-mentioned oil well blowout prevention box shunting decompression device is characterized in that: the connected mode between said connecting duct and the stator is welding.
Above-mentioned oil well blowout prevention box shunting decompression device, it is characterized in that: the quantity of said securing member is four, four said securing members are symmetrical set.
The utility model compared with prior art has the following advantages:
1, simple in structure, reasonable in design and easy to install, result of use is good.
2, can effectively make the liquid that draws up in the well obtain shunting release, liquid improves the blowout prevention leak preventing effect to the impact force of blowout prevention box in the well thereby reduce, and reduces environment pollution.
3, easily manufactured, and low cost of manufacture.
Through accompanying drawing and embodiment, the utility model is done further detailed description below.

The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises oil pick-up tube shutoff shunt assembly and is arranged on the connecting duct 1 on the said oil pick-up tube shutoff shunt assembly; Said oil pick-up tube shutoff shunt assembly comprises shutoff sheet 2, gasket seal 3 and the stator 4 that sets gradually, and said shutoff sheet 2, gasket seal 3 and stator 4 are fixed together through securing member 5; Said connecting duct 1 is fixedly connected with stator 4.
As depicted in figs. 1 and 2, in the present embodiment, have a plurality of pressure release return ports 6 on the said connecting duct 1, a plurality of said pressure release return ports 6 evenly are provided with; The pressure release return port be provided with that liquid plays pressure release backflow effect in the well that can be further suction be come up.
In the present embodiment, said securing member 5 is a bolt.
In the present embodiment, said gasket seal 3 is the rubber pad.
In the present embodiment, the connected mode between said connecting duct 1 and the stator 4 is welding.
In the present embodiment, the quantity of said securing member 5 is four, and four said securing members 5 are symmetrical set.
The installation and application of the utility model is: during installation; At first close down oil pumper, treat that borehole pressure takes off the blowout prevention box after the pressure release voluntarily, takes safe location with the blowout prevention box then; Be welded on an end of the connecting duct 1 of shunting decompression device the soffit of blowout prevention box 7; After conduit 1 to be connected is cooled to normal temperature,, again shutoff sheet 2 and gasket seal 3 and stator 4 are in the same place through bolt the other end of connecting duct 1 and stator 4 welding; To weld good shunting decompression device at last and be installed on the sucker rod 8 of oil pumper, can start the oil pumper operate as normal.In the course of work; Liquid in the well can draw up along the outer wall of sucker rod 8; Then draw up the liquid that comes and at first run into the shunting decompression device, therefore most liquid in the entering oil storage tank 9, have only small amount of liquid can continue to make progress along the outer wall of sucker rod 8 under the effect of shunting decompression device; These liquid are when through blowout prevention box 7, under the effect of blowout prevention box 7 in the entering oil storage tank 9.Like this, reduced in the well that suction comes up liquid greatly, made the liquid that draws up in the well obtain shunting release, improved the blowout prevention leak preventing effect, reduced environment pollution the percussion of blowout prevention box.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong in the protection domain of the utility model technical scheme according to the utility model technical spirit.
