Abstract
The utility model discloses a well mouth filtering device for high pressure water flooding, which comprises a valve, a connecting pipeline, a flow meter and a pressure meter, and the utility model also comprises a primary filter connected to the valve and a fine filter connected to the pipeline. The utility model can carry out the primary and fine double filtration forwards and carry out the cleanness of flow paths reversely, the water quality is ensured to be consistent with the water flooding standard, the strata are protected, and the oil-field development effect and the full clamping type connecting flow paths can be increased. The utility model has the advantages of simple structure, easy manufacture, installation and disassembly, rapidity and low cost, and the utility model can be used for developed water flooding process and is especially suitable for the well mouth for high pressure water flooding.
Description
One, technical field
The utility model relates to the oilfield injection water filter, relates in particular to a kind of high-pressure water injection well filter device of making a slip of the tongue.
Two, background technology
Existing oilfield injection water filtration system, generally all adopt and at water-injection station plain gauze is set and carries out water filtration, this filtration system is the indispensable facility of oil-field flooding, but also exist simultaneously because the pipeline from the water-injection station to the water injection well is long, corrosion is serious, thereby cause the pollution of water quality, and then cause formation contaminant, and directly influence normally carrying out of stratum water injection technology, also restricting the Oilfield developing effect simultaneously.
Three, summary of the invention
The purpose of this utility model provides a kind of improved high-pressure water injection well filter device of making a slip of the tongue, and shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art purify water effectively, and the oil field development effect is improved on the protection stratum.
The high-pressure water injection well described in the utility model filter device of making a slip of the tongue comprises valve and connecting pipe, flow meter and pressure meter, also comprises the initial filtrator and the fine filter that are connected on valve and the connecting pipe.
Wherein, described initial filtrator and fine filter are successively connected in series.Described valve, connecting pipe, strainer are clamp connection.Described initial filtrator is a cylinder-like structure, comprises the filter cartridge that housing and clip head and inner chamber thereof are installed, and this filter cartridge is fixed by filter disc and support.Described filter cartridge also can be the structure that is installed on screen pack on the conical pipe support, and its stub end is located on the clip head inner face.Described fine filter is a cylinder-like structure, comprises the tubular filter net that main body and inner chamber thereof are installed and filters reticulum.The tubular filter net of described fine filter, axial distribution is arranged, and installs on the joint that filters reticulum.Described tubular filter net is monolithic or split-type structural, and split type centre is linked to each other by pipe nipple.
The utility model has following advantage compared with prior art:
1, because water injection well is installed filter of the present utility model, can purify water, protect the stratum effectively, improve the oil field development effect.
2, forward carries out just, smart double filtration because the utility model adopts, and oppositely can carry out flow process and clean, and guarantees that water quality meets the injection standard, guarantees means for oil-field flooding provides new water quality.
3, adopt full clamping hoop type to connect flow process, simple in structure, make installing/dismounting easily, fast, cost is low, and is effective.
