Abstract
The utility model relates to a filter, in particular to a multi-wellhead filter applicable to the oilfield waterflooding. The multi-wellhead filter comprises a cylindrical tank body which is horizontally placed, wherein two ends and the middle of the tank body are provided with holes and hoop connectors; the hole at one end of the tank body is connected with a water inlet valve and a drain valve through pipelines; the hole at the other end of the tank body is connected with a water outlet valve through a pipeline; the hole in the middle of the tank body is connected with a drain valve through a pipeline; two-stage filter cores such as a coarse filter core and a metal sintering mesh filter core are arranged in the tank body; and the coarse filter core is arranged at one end of the water inlet valve and is coaxially arranged with the metal sintering mesh filter core. The utility model has the advantages that the filtering precision is high, the impurity in the water can be effectively filtered, the mechanical impurity and oil content in the water after filtration both meet the waterflooding requirement, the pollution to the oil layer is reduced, the rising velocity of the waterflooding pressure is slowed down, and the online backwashing regeneration and recycling can be realized.
Description
Technical field:
The utility model relates to a kind of filter, especially a kind of many well heads of oil-field flooding filter that is applicable to.
Background technology:
Oil-field flooding is to replenish stratum energy, keeps oilfield stable production, improves one of important measures of recovery ratio.Oilfield sewage had both helped the protection ring border as water filling water source reinjection into reservoir, had again than other water sources oil displacement efficiency preferably, thereby was widely adopted.But oilfield sewage contains higher suspended solid, floating carburetion, bacterium and harmful ion etc.This can cause the corrosion of water filling ground installation and the obstruction injury on stratum.Therefore, must satisfy the needs of water flooding according to the oil-field flooding water quality requirement to its purified treatment.The water injection well in oil fields at present commonly used filter of making a slip of the tongue has only single filtering material, and poor filtration effect can not be carried out online backwash.
Summary of the invention:
In order to overcome the make a slip of the tongue above-mentioned problem of filter of existing well, the utility model provides a kind of well head filter, and this well head filter can effectively purify injection water quality, the protection oil reservoir, and it is big to have a bearing capacity, can online backwash and regeneration, the characteristics of Shi Yonging repeatedly.
The technical solution of the utility model is:
Many well heads filter, include cylindrical tank, the two ends of tank body and centre have the hole and the clip interface are installed, the hole of tank body one end connects water intaking valve and blowoff valve by pipeline, the hole of the other end of tank body connects outlet valve by pipeline, hole in the middle of the tank body connects blowoff valve by pipeline, coarse filter element and metal sintering net filter core two-stage filter core are installed in the tank body, coarse filter element is positioned at water intaking valve one end, coarse filter element and the coaxial installation of metal sintering net filter core, coarse filter element does not contact with the end face of metal sintering net filter core.
Concrete, coarse filter element includes sleeve pipe and interior pipe, and interior pipe is positioned at inside pipe casing, and sleeve pipe and the coaxial installation of interior pipe have aperture on the barrel of sleeve pipe and interior pipe, and the bottom mounting flange of sleeve pipe and interior pipe is placed medium between sleeve pipe and the interior pipe.
During work, open water intaking valve and outlet valve, sewage enters in the interior pipe of coarse filter element by water intaking valve, enters sleeve pipe by the aperture on the inner tubal wall, filters through medium.Preliminary filtered sewage enters in the tank body from the aperture on the casing wall, passes metal sintering net filter core then and carries out secondary filter, and the clear water after filtering at last enters central tube by outlet valve, injects the down-hole through producing valve.
During backwash, open outlet valve, water enters tank body by outlet valve, and during backwash metal sintering net filter core, water is by discharging with the middle blowoff valve that is connected of tank body.During the backwash coarse filter element, water is discharged by the blowoff valve that is connected with tank body one end.
The beneficial effects of the utility model are filtering accuracy height, effectively impurity in the filtered water, mechanical admixture and oil content all reach waterflooding requirement in the water of filtration back, have reduced the pollution to oil reservoir, have slowed down the rate of climb of water injection pressure, can realize online backwash and regeneration, use repeatedly.The utility model is simple in structure, and survivability is strong, long service life.

The specific embodiment
Many well heads filter, include the cylindrical tank 1 of horizontal positioned, the two ends of tank body 1 and centre have the hole and clip interface 10 are installed, the hole of tank body 1 one ends connects water intaking valve 6 and blowoff valve 7.2 by pipeline, the hole of the other end of tank body 1 connects outlet valve 8 by pipeline, hole in the middle of the tank body 1 connects blowoff valve 7.1 by pipeline, coarse filter element and metal sintering net filter core 9 two-stage filter cores are installed in the tank body 1, coarse filter element is positioned at water intaking valve 6 one ends, coarse filter element does not contact with the end face of metal sintering net filter core 9 with metal sintering net filter core 9 coaxial installations, coarse filter element.Blowoff valve 7.1 and blowoff valve 7.2 all are communicated with blow-off line.
Coarse filter element comprises sleeve pipe 2 and interior pipe 3, and interior pipe 3 is positioned at sleeve pipe 2 inside, and sleeve pipe 2 and interior pipe 3 coaxial installations have aperture on the barrel of sleeve pipe 2 and interior pipe 3, and the bottom mounting flange 4 of sleeve pipe 2 and interior pipe 3 is placed medium 5 between sleeve pipe 2 and the interior pipe 3.
During work, open water intaking valve 6 and outlet valve 8, sewage enters in the interior pipe 3 of coarse filter element by water intaking valve 6, enter sleeve pipe 2 by the aperture on interior pipe 3 walls, filter through medium 5, the aperture from sleeve pipe 2 walls enters in the tank body 1, passes metal sintering net filter core 9 then and carries out secondary filter, clear water after filtering at last enters central tube by outlet valve 8, injects the down-hole through producing valve.
During backwash, open outlet valve 8, water enters tank body 1 by outlet valve 8, backwash metal sintering net filter core 9, and water is by discharging with the tank body 1 middle blowoff valve that is connected 7.1.During the backwash coarse filter element, water is discharged by the blowoff valve 7.2 that is connected with tank body 1 one ends.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
