Abstract
The utility model relates to a constant pressure metering well cleaning device for a water injection well in an oil field, which consists of a buffer separating tank, a pressure meter, a manual regulating valve, a blow-off valve, a water meter and a blow-off pipeline, and is characterized in that: the buffer separating tank is in a vertical cylindrical shape; the pressure meter is arranged on the top of the buffer separating tank; an inlet and an outlet are formed on the corresponding peripheral sides of the upper part of the buffer separating tank; the blow-off valve is arranged on the bottom upper part of the buffer separating tank; the manual regulating valve is arranged on the blow-off pipeline at the outlet; the water meter is arranged in front of the manual regulating valve; a blow-off valve connection pipeline and the blow-off pipeline are connected in parallel with each other and are connected with an external collection storage tank; and the inlet of the buffer separating tank is connected with a well cleaning valve at the opening of the water injection well. The utility model has the advantages that: a formation can be prevented from being excited so as not to produce sand through the control of the manual regulating valve, the difference between well cleaning liquid and discharge liquid can be compared through the metering of a flow meter, the magnitude of formation energy can be deduced, and a water injection scheme is convenient to make.
Description
Technical field
The utility model relates to a kind of water injection well in oil fields level pressure metering well washing apparatus, overcomes traditional open well-flushing and brings out the stratum and tell sand and sand and bury the stratum and cause annotating the problem of not intaking.
Background technology
The water injection well in oil fields well-flushing adopts relieving formula well-flushing mostly at present, well head well-flushing gate without any the blowout prevention procedure that builds the pressure, in washing well process, cause bottom pressure to descend suddenly, cause the excitement of well stratum to be shaked out, sand buries oil reservoir at the shaft bottom settling sand, the water water injection rate is reduced even annotate and do not intake, have a strong impact on the oil field and dynamically adjust, be unfavorable for the stable yields in oil field.Strengthen the operation well workover frequency of well simultaneously, paid a large amount of maintenance costs.
Summary of the invention
The purpose of this utility model provides a kind of water injection well in oil fields level pressure metering well washing apparatus, overcomes the defective that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of buffering knockout drum, pressure meter, manual modulation valve, blowoff valve, water meter and blowdown pipeline, it is characterized in that cushioning knockout drum and be made as vertical type cylinder shape, the top is provided with pressure meter, the corresponding all sides in top are provided with an import and an outlet, top, the end is provided with a blowoff valve, be provided with manual modulation valve on the outlet blowdown pipeline, be provided with water meter before manual modulation valve, the blowoff valve connecting line is connected with the collected outside storage tank with the blowdown pipeline parallel connection; The import of buffering knockout drum is connected with the flushing valve of water injection well.
Operating principle of the present utility model and advantage are that silt particle and the bottom hole falling article that well-flushing washes out at first enters the buffering knockout drum, under the effect of pressure reduction suddenly and difference in specific gravity, solid separates the bottom that falls into the buffering knockout drum with sewage, the sewage of well-flushing is through the control of Manual pressure control valve, measure through flow meter, collection storage tank outside blowdown pipeline enters this device, pull away with car, prevent the pollution of the environment, by the control of Manual pressure control valve, can prevent to bring out the stratum excitement and shake out, can contrast flushing fluid and the difference of discharging liquid by the flow meter metering, deducibility goes out the size of stratum energy, is convenient to formulate waterflood project.

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 made up of buffering knockout drum 1, pressure meter 2, manual modulation valve 3, blowoff valve 5, water meter 4 and blowdown pipeline 6, it is characterized in that cushioning knockout drum and be made as vertical type cylinder shape, the top is provided with pressure meter, the corresponding all sides in top are provided with an import and an outlet, top, the end is provided with a blowoff valve, be provided with manual modulation valve on the outlet blowdown pipeline, be provided with water meter before manual modulation valve, the blowoff valve connecting line is connected with the collected outside storage tank with the blowdown pipeline parallel connection; The import of buffering knockout drum is connected with the flushing valve of water injection well.
When using the utility model, the import of buffering knockout drum 1 is connected with the flushing valve of water injection well with steel pipe or high-pressure hose, blowdown pipeline 6 is connected with device collection storage tank outward, close water filling gate 7, open sleeve gate 9 beginning well-flushings, open flushing valve 8 entirely, flushing fluid comes water pipeline 10 to enter the empty lock of tubing and casing annular from well-flushing or water filling, washing feed liquor returns the well oil pipe and carries silt particle from entering the end, bottom hole falling article enters buffering knockout drum 1 from flushing valve, the solid impurity that flushing fluid carries falls into the bottom of buffering knockout drum, seeing the pressure manual modulation valve 3 adjusting pressure of pressure meter 2 indications, size adjustment according to stratum energy is advisable to not allowing stratum generation excitement not shake out, the well-flushing effluent sewerage enters water meter 4 and measures, contrast enters the difference of the flushing fluid that returns out of the flushing fluid in the well, analyze formation leakage, take corresponding well workover measure according to different situations.
