Abstract
The utility model relates to a mouthpiece enclosure used for an oil field, in particular to a mouthpiece enclosure with a filtering device. The mouthpiece enclosure with a filtering device comprises a mouthpiece enclosure normally used in the oil field and a filtering device arranged in the oil field. The mouthpiece enclosure comprises a mouthpiece enclosure connecting pipe, a mouthpiece enclosure main body and a mouthpiece enclosure water inlet pipe. Wherein, the mouthpiece enclosure main body is a cavity circular pipe, the mouthpiece enclosure connecting pipe is communicated at the front end of the cavity circular pipe, a baffle plate with a centre opening is arranged at the connecting position of the both, an inner screw thread is arranged at the right end of the mouthpiece enclosure main body, and a pipe plug is turned in the inner screw thread. The mouthpiece enclosure water inlet pipe is communicated at the lower part of the mouthpiece enclosure main body. The filtering device is arranged in the mouthpiece enclosure main body, the device fixes the top pressure of the filtering device through a pipe plug. The foreign impurities in water are removed through the filtering device, the service life of a subsurface tool is increased, the pollution of an oil layer is simultaneously avoided, and the filtering device can be conveniently and regularly cleaned.
Description
1, technical field:
The utility model relates to a kind of oil field mouthpiece cover, relates in particular to a kind of mouthpiece cover that has filter.
2, background technology:
Be threeway import the effect of oil well with water with the mouthpiece cover that uses of oil field now, but such water includes a large amount of impurity, causes the downhole tool obstruction easily, and understand polluted reservoir.
3, summary of the invention:
The purpose of this utility model is to propose a kind of mouthpiece cover that has filter that can filter the impurity in the water of oil field.
The purpose of this utility model is achieved in that the mouthpiece cover that has filter is overlapped by oil field mouthpiece commonly used and installing filter is within it formed.The mouthpiece cover is made up of mouthpiece cover tube connector, mouthpiece cover main body and mouthpiece cover water inlet pipe.Wherein mouthpiece cover main body is a cavity pipe, is communicated with mouthpiece cover tube connector at its front end, and both junctions are provided with the plate washer of center drilling, and mouthpiece cover main body right-hand member is provided with internal thread, is rotary with plug in it.Below mouthpiece cover main body, be communicated with mouthpiece cover water inlet pipe.Be provided with filter in the mouthpiece cover main body, this device is fixed its roof pressure by plug.
Owing to adopt technique scheme, with contaminant removal in the water, increased the application life of downhole tool by filter, avoided the pollution of oil reservoir simultaneously.And filter is periodic cleaning easily.

Legend: 1, filter seal head, 2, filter grid, 3, collet, 4, draw ring, 5, steel bar, 6, screen pack, 7, Inner filter net, 8, mouthpiece cover tube connector, 9, sealing ring, 10, mouthpiece cover main body, 11, plug, 12, mouthpiece cover water inlet pipe.
5, the specific embodiment:
Embodiment 1: shown in Fig. 1,2,5, the mouthpiece cover that has filter is made up of oil field mouthpiece cover and installing filter within it commonly used.The mouthpiece cover is made up of mouthpiece cover tube connector 8, mouthpiece cover main body 10 and mouthpiece cover water inlet pipe 12.Wherein mouthpiece cover main body 10 is a cavity pipe, be communicated with mouthpiece cover tube connector 8 at its front end, both junctions are provided with the plate washer of center drilling, and mouthpiece cover main body 10 right-hand members are provided with internal thread, be rotary with plug 11 in it, plug Nei Kelian puts devices such as sky gate.Below mouthpiece cover main body 10, be communicated with mouthpiece cover water inlet pipe 12.Be provided with filter in the mouthpiece cover main body 10.This filter is by filtering seal head 1, be welded on the steel bar 5 that filters seal head 1 lower end, be wrapped in the steel disc on the steel bar 5, and collet 3 and draw ring 4 are formed.Filtering seal head 1 is the cavity cylinder, has the twice groove on its surface, is with sealing ring 9 in the groove.Ring filters seal head 1 lower surface circumference and is welded with steel bar 5, is wound with steel disc from top to bottom along steel bar 5, leaves the gap between every layer of steel disc, promptly forms filter grid 2, and the gap is serving as easy at 0.3-0.5mm.Be welded with collet in steel bar 5 lower ends, collet 3 lower ends are welded with draw ring 4.
During use, will filter seal head 1, put into mouthpiece cover main body 10, screw on plug 11, filter is fixed towards mouthpiece cover tube connector 8 directions.By water pump the watering place water is pumped in the mouthpiece cover main body 10 subsequently, the water that pump into this moment leads to the ground extracting device of oil by mouthpiece cover tube connector 8 after filtering by filter grid 2 again, enters oil reservoir at last.When needing the cleaning filter, only need turn on plug 11
Embodiment 2: shown in Fig. 3,4, be welded with the cylindric Inner filter net 7 of cavity between filtration seal head 1 and collet 3, its surface spreads all over through hole, and it plays the effect that increases integral rigidity.Illiteracy has screen pack 6 on the Inner filter net surface, screen pack 6 upper ends and the 1 lower surface welding of filtration seal head, and screen pack 6 lower ends and collet 3 welding leave certain interval between screen pack 6 and the Inner filter net 7.Through hole is greater than aperture on the screen pack 6 on the Inner filter net 7, and it also is thicker than screen pack 6 simultaneously.Can select the corresponding order number sieve net that filters according to impurity screening, increase filter area, all the other are with embodiment 1.
