Description
One, technical field
The utility model relates to a kind of water injection well well head filter plant, and specifically a kind of water injection well comes water filter.
Two, background technology
Water injection well in oil fields is all distant from water-injection station at present, because all to be oil field extracted water treated carries out re-injection in the water injection well water filling, add-back sewage does not often reach the re-injection standard, water contains hydrogen sulfide or materials such as calcium carbonate, magnesium carbonate, waterflood-transmission line is had very big corrosion, and corrosion dirt down enters the stratum stratum is produced pollution and obstruction water filling matter repeated contamination, intact do not become water filling matter mark, influence the oil well crude output.
Three, summary of the invention
The purpose of this utility model provides a kind of water injection well and comes water filter, solves the contaminated problem that influences injectivity index and oil well crude output of injection water quality that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model is by strainer cover, filter body, outlet pipe, outlet valve, screen casing, screen pack, water inlet pipe, water intaking valve and blowoff valve are formed, filter body is established cylindrical, upper top is provided with and the bolted strainer cover of filter body, the center is provided with the reducing hole, the big lower diameter of upper diameter is little, on the undergauge step, be provided with screen pack, between screen pack and strainer cover, be provided with screen casing, the filter body upper right is provided with outlet pipe, outlet pipe is provided with outlet valve, be provided with water inlet pipe in the filter lower left side, on water inlet pipe, be provided with water intaking valve, be provided with blowoff valve in filter bottom.
The utility model is installed to the water injection well well head, can filter coming water, and anvil cinder in the water and dirty slag can in time give filter down, makes the not contaminated and obstruction of water filling layer, has guaranteed finishing of injectivity index.

1-strainer cover 2-screen casing 3-outlet pipe 4-outlet valve 5-filter body 6-screen pack 7-water inlet pipe 8-water intaking valve 9-blowoff valve among the figure
Four, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is by strainer cover 1, filter body 5, outlet pipe 3, outlet valve 4, screen casing 2, screen pack 6, water inlet pipe 7, water intaking valve 8 and blowoff valve 9 are formed, it is cylindrical to it is characterized in that filter body is made as, upper top is provided with and the bolted strainer cover of filter body, the center is provided with the reducing hole, the big lower diameter of upper diameter is little, on the undergauge step, be provided with screen pack, between screen pack and strainer cover, be provided with screen casing, the filter body upper right is provided with outlet pipe, outlet pipe is provided with outlet valve, be provided with water inlet pipe in the filter lower left side, on water inlet pipe, be provided with water intaking valve, be provided with blowoff valve in filter bottom.
When using the utility model, it is installed in well head water filling gate and comes between the water pipeline, water inlet pipe 7 is with coming the water pipeline welding, and outlet pipe 3 and water injection well water inlet pipe welding one are opened water intaking valve 8 and outlet valve 4, come water net filtration after filtration, enter water injection well by screen casing 2 and outlet pipe 3, enter the water filling layer, impurity in the water under the filter, regularly drain, guaranteed that injection water quality and water filling layer are not contaminated from blowoff valve 9.
