Description
Technical field
The utility model relates to oil-field water process field, and a kind of oil field height is containing poly-produced water disposal device specifically.
Background technology
In order to improve oil recovery factor further, oil field have employed high concentration polymer technology of reservoir sweep, because the increase of injection of polymer molecular weight, implantation concentration increase, in the recovered water of ground, polymer content is more and more higher, cause Gao Handu to gather recovered water and have many characteristics being different from conventional poly-drive water exit, main manifestations is: the features such as in recovered water, polymer content is high, viscosity is large, emulsification is serious, oil bead diameter is little, the increasing of oily water separation difficulty.For height containing poly-recovered water, adopted conventional polymer drive water exit process frock to put, i.e. " natural subsidence+coagulant precipitation+quartz sand filtration ", but the water outlet after this device process is difficult to reach poly-drives Thief zone reinjected water index request in the past.
Summary of the invention
Poly-deficiency of driving Thief zone reinjected water index request is reached at process height containing being difficult to case during poly-recovered water in order to overcome existing oil-field water treatment facility, the utility model provides a kind of oil field height containing poly-produced water disposal device, this oil field height reaches poly-containing the water outlet after poly-produced water disposal device makes process and drives Thief zone reinjected water index request, reduce environmental pollution, improve oilfield economic benefit.
The technical solution of the utility model is: a kind of oil field height is containing poly-produced water disposal device, comprise raw water tubes line, pressure filter, described raw water tubes line is connected with air flotation oil removal tank water-in, air flotation oil removal tank water outlet is connected with coagulation oil removing pot, and air flotation oil removal tank top oil outlet is connected with oil tank, described coagulation oil removing pot water outlet connects surge tank, coagulation oil removing pot top oil outlet is connected with oil tank, described surge tank water outlet Bonding pressure filter tank, pressure filter top water outlet connects recovery pond, bottom line is connected with recoil cleaning of evaporator and outer defeated tank respectively.
The source line of described coagulation oil removing pot is provided with coagulating agent chemical feeding points.
Described pressure filter bottom line is connected with recoil cleaning of evaporator and outer defeated tank respectively.
The utility model has following beneficial effect: owing to taking such scheme, and raw water tubes line is connected with air flotation oil removal tank, accelerates oil droplet ascent rate, thus improve the oily water separation efficiency of slurry tank by air supporting, then through coagulation oil removing pot and pressure filter; Backwashing pump is adopted to carry out back flushing to the filtrate in pressure filter, improve media regeneration quality, thus improve filter effect, improve the high separating effect containing poly-extraction oil-in-water, water, solid material, make the water outlet after process reach poly-and drive Thief zone reinjected water index request, become an important channel of reducing environmental pollution, ensureing oil field Sustainable Exploitation, improving oilfield economic benefit.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
1-raw water tubes line in figure, 2-air flotation oil removal tank, 3-coagulating agent chemical feeding points, 4-coagulation oil removing pot, 5-surge tank, 6-boosting pump, 7-pressure filter, 8-backwashing pump, 9-recoils cleaning of evaporator, the outer defeated tank of 10-, 11-output pump, 12-reclaims pond, 13-recovered water pump, 14-oil tank, 15-oil pump.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of oil field height is containing poly-produced water disposal device, and comprise raw water tubes line 1, pressure filter 7, described raw water tubes line 1 is connected with air flotation oil removal tank 2 water-in, air flotation oil removal tank 2 water outlet is connected with coagulation oil removing pot 4, and air flotation oil removal tank 2 top oil outlet is connected with oil tank 14.The source line of coagulation oil removing pot 4 is provided with coagulating agent chemical feeding points 3, in pipeline, add coagulating agent by it, described coagulation oil removing pot 4 water outlet connects surge tank 5, and coagulation oil removing pot 4 top oil outlet is connected with oil tank 14, oil tank 14 exports and connects oil pump 15, thus is discharged by sump oil.Described surge tank 5 water outlet pipeline is connected with boosting pump 6, the outlet Bonding pressure filter tank 7 of boosting pump 6.Described pressure filter 7 top water outlet connects recovery pond 12, reclaims pond 12 and is communicated with raw water tubes line 1 by recovered water pump 13.Pressure filter 7 bottom line is connected with recoil cleaning of evaporator 9 and outer defeated tank 10 respectively, and the water purification after filtration enters in outer defeated tank 10, and outer defeated tank 10 connects output pump 11, is discharged by water purification by output pump 11.Meanwhile, recoil cleaning of evaporator 9 is communicated with pressure filter 7 bottom line by backwashing pump 8, when filtrate needs cleaning, carries out back flushing to the filtrate in pressure filter 7.
Height enters air flotation oil removal tank 2 containing poly-recovered water by raw water tubes line 1, is accelerated the ascent rate of oil droplet, a part of oil is entered oil tank 14 by air supporting function, enters coagulation oil removing pot 4, more a part of sump oil is entered oil tank 14 after remaining sewage adds coagulating agent.Enter pressure filter 7 through the sewage of coagulation oil removing pot 4 oil removing to filter, pressure filter 7 adopts quartz sand, magnetite double-layer filter material to filter, water purification major part after filtration enters outer defeated tank 10 by bottom line, outer defeated by output pump 11 again, another part enters recoil cleaning of evaporator 9, waits for and carries out back flushing to pressure filter.When the filtrate in pressure filter 7 needs cleaning, by backwashing pump 8, the water in recoil cleaning of evaporator 9 is injected in tank by pressure filter 7 bottom line, back flushing is carried out to filtrate, now, pressure filter 7 upper outlet pipeline is opened, backwashing sewage water enters and reclaims pond 12, then pumps into raw water tubes line 1 by recovered water pump 13 and carry out recirculation.
Adopt described Technology process height containing poly-recovered water, water outlet after process can reach poly-and drive Thief zone reinjected water index request (i.e. oleaginousness≤20mg/L, suspended solids≤20mg/L, median particle size≤5mg/L), become minimizing environmental pollution, ensure oil field Sustainable Exploitation, improve an important channel of oilfield economic benefit.
