Description
Technical field
The utility model relates to oilfield, specifically the simple and easy water treatment filter of a kind of oil-field flooding.
Background technology
After exploitation is dropped in oil field, along with the growth of recovery time, the energy of oil reservoir own will constantly be consumed, cause formation pressure constantly to decline, underground crude oil is degassed in a large number, and viscosity increases, oil well output greatly reduces, and even stop-spraying can stop production, causes underground to remain a large amount of dead oil and can not adopt out.In order to the underground of causing after making up crude oil extraction is in debt, keep or improve formation pressure, realize oil field stable high yield, and obtain higher recovery ratio, water filling must be carried out to oil field, the content of the impurity such as suspension, oil content, minitype particle such as the water noted will be checked on through strict, the minimizing sandy soil will tried one's best in the inside.Current oil-field flooding can carry out preliminary filtration and purification before water injecting pump, but after water injecting pump, often can produce again the impurity made new advances, comprise: sandy soil suspension, scale, the impurity such as oil content, minitype particle, entering like this in the water of water injection well containing a lot of impurity, and to cause water filling to reach standard.
Summary of the invention
Cause water filling cannot reach the deficiency of standard to overcome existing oil-field flooding new impurity can be produced again after water injecting pump, the utility model provides a kind of oil-field flooding simple and easy water treatment filter, the simple and easy water treatment filter of this oil-field flooding is connected on waterflood-transmission line, the minitype particles such as suspension and oil content such as sandy soil contained in the water after water injecting pump can be separated, by further for noted water advanced treating, to reach oil-field flooding standard.
The technical solution of the utility model is: the simple and easy water treatment filter of a kind of oil-field flooding, comprise waterflood-transmission line, waterflood-transmission line is provided with into water shutoff valve, the end of described waterflood-transmission line is connected with filter cup, the top delivery port of filter cup is connected by pipeline treats water injection well, and pipeline is provided with water outlet shutoff valve; Be equipped with screen pack and active carbon film in described filter cup respectively, bottom filter cup, be provided with riffler.
Described screen pack and active carbon film are all horizontally fixed on filter cup inside, and screen pack is placed in active carbon film bottom and the two does not contact.
Be connected with bottom described riffler and put husky mouth bolt.
The utility model has following beneficial effect: owing to taking such scheme, this filter make use of the principles such as filter cup reducing reduction of speed, gravitational settling, multistage filtering net, charcoal absorption, the minitype particles such as suspension and oil content such as the sandy soil contained in the water after water injecting pump are separated, by further for noted water advanced treating, reduce entering, to reach oil-field flooding standard of impurity.Thus improve the water-injection efficiency in oil field, increase water injection rate, realize oil field stable high yield, and obtain higher recovery ratio.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
1-water inlet shutoff valve in figure, 2-steel pipe, 3-screen pack, 4-active carbon film, 5-filter cup, 6-water outlet shutoff valve, 7-riffler, 8-puts husky mouth bolt, and 9-waterflood-transmission line, 10-treats water injection well.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the simple and easy water treatment filter of a kind of oil-field flooding, comprise waterflood-transmission line 9, waterflood-transmission line 9 is provided with into water shutoff valve 1, the end of described waterflood-transmission line 9 is connected with filter cup 5, and the water inlet on the top of filter cup 5 is in bottom, and delivery port is upper, the delivery port of filter cup 5 is connected by pipeline treats water injection well 10, and pipeline is provided with water outlet shutoff valve 6.Screen pack 3 and active carbon film 4 is equipped with respectively in described filter cup 5, wherein screen pack 3 and active carbon film 4 are all horizontally fixed on filter cup 5 inside, screen pack 3 is placed in active carbon film 4 bottom, and vertical direction has a segment distance therebetween, and namely the two does not contact.
Be provided with the riffler 7 to lower recess bottom filter cup 5, be provided with bottom riffler 7 and put husky mouth bolt 8.
The shutoff valve of the 25MPa that above-mentioned shutoff valve adopts oil field special; The material of steel pipe all adopts the withstand voltage seamless steel pipe of GB/T1497 Wuxi steel pipe 6-1994(fluid conveying stainless steel), prevent from working in the process of high pressure, occur security incident; Screen pack 3 adopts stainless steel material, and the multistage filtering net successively decreased by large net to little net, to ensure suspension not by screen pack; Active carbon film 4 adopts bulky grain shape, ensures high adsorption capacity; What subsider employing was very little connects husky mouth, prevents too much water from entering in subsider, is again poured in water by sandy soil.
When opening into water shutoff valve 1 and water outlet shutoff valve 6, water in waterflood-transmission line 9 can enter filter cup 5, because filter cup 5 diameter is greater than pipeline diameter, after such water enters filter cup, pressure drop, the flow velocity of current decline, the ability of carrying sandy soil of current declines, and under gravity, the sedimentation of suspensions such as heavier sandy soil are in riffler 7; Water through deposition upwards filters through multistage filtering net 3, and the impurity such as the sandy soil contained in current are trapped in below screen pack 3, and then is deposited to bottom; Water after filtration upwards flows through active carbon film, and the oil content contained in current and minitype particle can be adsorbed onto activated carbon surface by active carbon film, and current are purified further.Last current are injected into through water outlet shutoff valve 6 and treat in water injection well 10.Along with the injection of water, the suspensions such as the sandy soil deposited in subsider 7 can constantly increase, because riffler is transparent, so in time seeing that riffler inner suspension thing is a lot, first flood pattern is closed, then husky mouth bolt 8 is put in slowly turn of leaning to one side, and is discharged by the suspension in riffler 7.
The application of above-mentioned simple and easy water treatment filter; solve the water treatment problem in oil field flood pattern; be about to enter treat water injection well before again water filling is carried out to filtration and the process of the degree of depth, huge effect is played in the protection for oil field oilbearing stratum, has far reaching significance to oil-field flooding operation.
