Abstract
The utility model relates to a filtering device for sewage exploited from a water injection well in oilfield development. The filtering device for the sewage exploited from the water injection well in the oilfield development mainly resolves the problem in the prior art that when the sewage containing a great number of impurities is injected back to the stratum under the shaft, the middle and later period development of an oil filed are seriously affected. The filtering device for the sewage exploited from the water injection well in the oilfield development is characterized in that a steel net (3), a supporting plate (6) and a filtering plate (8) are sequentially arranged inside a tank body (2) from top to bottom, a filtering layer (4) is arranged on the supporting plate (6), the wall of the tank body between the supporting plate (6) and the filtering plate (8) is provided with an air inlet pipe (5) and a blind plate (7), a filtering net (11) is arranged in a water outlet pipe (10), and a valve (12) is connected on the water outlet pipe (10) at the lower portion of the filtering net (11). The filtering device for the sewage exploited from the water injection well in the oilfield development can remove a great number of impurities in oil-water mixed sewage, and is good in filtering effect.
Description
Technical field
The utility model relates to a kind of filter in the oil gas well development field, particularly a kind of oil field development water injection well extraction sewage filter device.
Background technology
The most of oil field of China has entered mid-term and the later stage of oil exploitation, and sewage content reaches 70～80% in the extraction liquid of extraction crude oil, the oil field that has even up to 90%.When this part oil well is carried out the water filling operation, consider from water saving and environmental angle, usually oil well is gone in the produced-water reinjection after handling in the extraction liquid.From the oil-water mixture sewage that extract out the down-hole, contain a large amount of impurity.When down-hole formation is gone in the produced-water reinjection that contains a large amount of impurity, after operation after a while, this impurity can accumulate in the rock stratum gradually, can influence water injection rate, the rock stratum is stopped up fully, do not reach the purpose of displacement of reservoir oil by filling water, so that the water filling operation can not be implemented fully, have a strong impact on the middle and later periods exploitation in oil field.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the produced-water reinjection that will contain a large amount of impurity that exists in the background technology to go into the problem that down-hole formation has a strong impact on the exploitation of oil field middle and later periods, and provide a kind of oil field development water injection well extraction sewage filter device, this oil field development water injection well extraction sewage filter device, can sweep off impurity in the oil-water mixture sewage, good filtration effect.
The invention for solving the technical problem can reach by following technical solution: this oil field development water injection well extraction sewage filter device comprises tank body, tank body top and bottom are respectively arranged with water inlet pipe and outlet pipe, the bottom is provided with sewage draining exit, and described tank interior is equipped with steel mesh, gripper shoe, filter from top to bottom successively; Have the hole on the filter, be equipped with filter material layer on the gripper shoe; Air inlet pipe, blind plate are housed on the tank wall between gripper shoe and filter; Described outlet pipe is built-in with screen pack, is connected to valve on the outlet pipe of screen pack bottom.
The utility model is compared with the above-mentioned background technology can have following beneficial effect: this oil field development water injection well extraction sewage filter device is owing to adopt said structure, sewage enters tank body by water inlet pipe, go out earlier the bulk dirt by steel mesh, filtering the back outlet pipe by filter material layer then discharges, the screen pack that is equipped with in the outlet pipe and filter are used for filtering the filtrate that sewage carries, and re-use; The fine impurities soiling solution falls into the bottom by filter and discharges by sewage draining exit; Space between gripper shoe and filter is used for depositing filters and the impurity of sedimentation, when filtration beds blocks or lower space is deposited impurity more for a long time, can introduce compressed air by air inlet pipe filter material layer is recoiled.The utility model is simple in structure, easy to operate, good filtration effect and easy to maintenance, has improved the quality of water filling greatly.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Among the figure: 1-water inlet pipe, 2-tank body, 3-steel mesh, 4-filter material layer, 5-air inlet pipe, 6-gripper shoe, 7-blind plate, 8-filter, 9-sewage draining exit, 10-outlet pipe, 11-screen pack, 12-valve, 13-flange, 14-gathering line.
The specific embodiment
Below in conjunction with accompanying drawing will the utility model is described in further detail:
As shown in Figure 1, this oil field development water injection well extraction sewage filter device comprises tank body 2, tank body 2 tops and bottom are respectively arranged with water inlet pipe 1 and outlet pipe 10, and the bottom is provided with sewage draining exit 9, and described tank body 2 inside are equipped with steel mesh 3, gripper shoe 6, filter 8 from top to bottom successively; Filter is the arcwall face that Open Side Down, is equipped with filter material layer 4 on the gripper shoe 6; Air inlet pipe 5, blind plate 7 are housed on the tank wall that gripper shoe 6 and filter are 8; Described outlet pipe 10 is built-in with screen pack 11, is connected to valve 12 on the outlet pipe 10 of screen pack 11 bottoms; Screen pack 11 front portions of described outlet pipe 10 are connected to gathering line 14, and the top of gathering line 14 and bottom are connected with valve and flange 13, and the filtrate that filters in the outlet pipe 10 is deposited in the gathering line 14, open flange 13 filtrate is discharged, and re-use.
During use, sewage enters tank body by water inlet pipe 1, removes the bulk dirt earlier by steel mesh, filtering back outlet pipe 10 by filter material layer 4 then discharges, be equipped with screen pack 11 in the outlet pipe 10, screen pack 11 and filter 8 are used for filtering the filtrate that sewage carries, and re-use; The fine impurities soiling solution falls into the bottom by filter 8 and discharges by sewage draining exit 9, the space that gripper shoe 6 and filter are 8 is used for depositing the impurity of filtration and sedimentation, when filter blocks or lower space is deposited impurity more for a long time, can introduce compressed air by air inlet pipe 5 recoils to filter material layer 4, impurity is discharged by sewage draining exit, can carry out normal filter operation.
