Abstract
The invention discloses a kind of compound oil field water process antisludging agent, oil field water process can not be effectively applicable to by solving existing antisludging agent, due to the problem of influence of crude oil causes treatment effect bad during processing.The present invention according to percent by weight, including：The methoxy amphetamine 5 20% of 4 hydroxyl 3；Polyacrylic acid 10 30%；Aromatic thiazole 10 30%；Carboxyl ethylene phosphoric acid 20 50%；Remaining is deionized water.The present invention can effectively avoid crude oil from preventing antisludging agent the influence of fouling, improve the effect of scale inhibition, and effectively reduce the dosage of antisludging agent, and effect is very notable.
Description
Technical field
The present invention relates to antisludging agent, and in particular to a kind of compound oil field water process antisludging agent.
Background technology
At present, in oilfield produced water system, one of the problem of fouling is the most serious run into Water-quality control.Fouling can be sent out
Life is in each position on stratum, pit shaft or ground, some wells and oil reservoir because dirt is too early in the production layer deposition of pit shaft borehole
Ground is discarded；Fouling can also occur to set in gravel packing zone, down-hole pump, oil pipe column, oil nozzle and oil-stocking equipment, gathering line etc.
Standby and water treatment system any position.Fouling can produce to oil field and bring serious harm；Led because incrustation scale belongs to the bad of heat
Body, the formation of incrustation scale greatly reduce heat-transfer effect；Oil reservoir and near wellbore zone fouling, gas channel can be blocked, reduce oil reservoir and ooze
Saturating rate, declines oil well output.The deposition of incrustation scale can cause equipment and the local corrosion of pipeline, perforate and destroy in a short time；
Incrustation scale can also reduce water flow section product, increase resistance to water-flow and conveying energy, rolled up cleaning charge and repair time.
Flood pattern fouling, rises water injection pressure, and energy consumption increases and production capacity reduces.
Oilfield scaling mainly has two big reasons：First, stratum water contains the easy fouling salt ion of high concentration, in oil recovery process
Pressure, temperature or water constituent change change original chemical balance and produce dirt, and main dirty composition is calcium carbonate, can be mixed with carbon
Sour magnesium, calcium sulfate etc..Second, two or more incompatible water mixing, scale-forming ion interact and generate dirt, the most
It common are barium sulfate and strontium sulfate scale.Particularly in offshore oilfield seawater injection recovery process, stratum water often contains barium strontium ion,
And seawater contains substantial amounts of sulfate ion, both mix the barium and strontium sulfate for producing indissoluble.
Also, oil extraction in oil field factory recovered water is to be come out with crude oil from reservoir exploitation, and generation is not only carried in waste water
Various salts and gas ion in the stratum such as the calcium of crude oil, magnesium, barium, strontium, carbonate, sulfate radical, also carry crude oil.Adopting
During oil, thus oil field extracted water be present not only COD and oil content are high, and the problem of temperature is high, salinity is high.
Existing antisludging agent can not be effectively applicable to oil field water process, because the influence of crude oil causes treatment effect during processing
It is bad.
The content of the invention
The technical problems to be solved by the invention are：Existing antisludging agent can not be effectively applicable to oil field water process, processing
When due to the problem of influence of crude oil causes treatment effect bad, and it is an object of the present invention to provide it is a kind of solve the above problems it is compound
Oil field water process antisludging agent.
The present invention is achieved through the following technical solutions：
A kind of compound oil field water process antisludging agent, according to percent by weight, including：
Remaining is deionized water.
It by the optimization of said components and proportioning, can effectively avoid crude oil from preventing antisludging agent the influence of fouling, improve resistance
The effect of dirt, and the dosage of antisludging agent is effectively reduced, effect is very notable.
Further, include according to percent by weight, the present invention：
Remaining is deionized water.
Preferably, the present invention is made up of according to percent by weight following components：
Remaining is deionized water.
As optimal set-up mode, according to percent by weight, the present invention is made up of following components：
Remaining is deionized water.
The present invention compared with prior art, has the following advantages and advantages：
1st, by the optimization of component and proportioning of the invention, crude oil can be effectively avoided to prevent antisludging agent the influence of fouling,
The effect of scale inhibition is improved, and effectively reduces the dosage of antisludging agent, effect is very notable；
2nd, instant component is few, dosage is few, cost is low, and the equipment such as pipe container will not be caused to corrode, to environment
It is pollution-free, environmentally friendly.
