Abstract
This invention relates to a polymer flooding wastewater treatment cleaning agent and its preparation method. Said method comprises preparing an intermediate first and making the polymer flooding wastewater cleaning agent from the intermediate and triethanolamine oleate soap. The formula includes 30~60 wt.% intermediate and 40-70 wt.% triethanolamine oleate soap, wherein the intermediate includes raw materials of 15~30 wt.% polyoxyethylene fatty alcohol ether, 8-20 wt.% octyl phenol polyoxyethylene ether, 10-28 wt.% dodecyl diethanolamide, and 30-50 wt.% water. The polymer flooding cleaning agent can make the wastewater treated meet the requirement of reinjection water (oil content<=20mg/L and suspended solids content<=20mg/L). Wastewater treatment filter plugging problems caused by flooding produced liquid are solved. As the treated wastewater effluents are reinjected to the formation, formation pressure is increased, water resource is saved, and oilfield environment is protected.
Description
Technical field
The present invention relates to technical field of sewage, particularly a kind of clean-out system of handling oilfield sewage is a kind of oil field focus drive sewage treatment cleaning agent prescription and preparation method thereof.
Background technology
At present, China's main oilfield has entered the polymer flooding raising recovery ratio stage.The using polymer displacement of reservoir oil has obtained good economic benefit.Field polymers displacement of reservoir oil extraction liquid need be deviate from sewage disposal, the produced-water reinjection stratum that will deviate from.But what the polymer flooding major part was used is polyacrylamide, owing to contain a certain amount of polyacrylamide in the sewage, the effluent treatment and filtering device that often results in blockage must clean strainer No. one time about 8 hours, brought sizable difficulty to production management; And contain polyacrylamide in the sewage, increased the intractability of oil-containing and suspended substance in the sewage greatly.Conventional oily water treatment agent can not be finished the requirement of extraction sewage disposal well, and the sewage quality after the processing can not reach the requirement of re-injection, influences finishing of produced-water reinjection task.
Summary of the invention
The objective of the invention is: a kind of oil field focus drive sewage treatment cleaning agent prescription and preparation method thereof is provided.Utilize clean-out system to dispose of sewage, improve polymer flooding extraction liquid and deviate from the sewage quality, reach the requirement of re-injection, solve effluent treatment and filtering device blockage problem.
The technical scheme that the present invention is taked for its technical problem of solution is:
The raw material of focus drive sewage treatment cleaning agent and prescription:
Raw material comprises:
1, polyoxyethylene aliphatic alcohol ether (industrial goods);
2, polyoxyethylene octyl phenolic ether (industrial goods);
3, dodecyl diglycollic amide (industrial goods), structural formula is C
11H
23CON (C
2H
4OH)
2
4, trihydroxy ethylamine oleate soap (industrial goods);
5, water.
Focus drive sewage treatment cleaning agent, the formulation weight ratio is: intermediate: 30～60%; Trihydroxy ethylamine oleate soap: 40～70%.Wherein: the raw material weight ratio of intermediate is: polyoxyethylene aliphatic alcohol ether: 15～30%; Polyoxyethylene octyl phenolic ether: 8%～20%, the dodecyl diglycollic amide: 10～28%, water: 30～50%.
The preparation method of focus drive sewage treatment cleaning agent of the present invention be divided into following two the step finish:
The preparation of A, intermediate
It with weight ratio 15～30% polyoxyethylene aliphatic alcohol ether, weight ratio is 8～20% polyoxyethylene octyl phenolic ether, weight ratio is that 10～28% dodecyl diglycollic amide places the enamel still that is mixed successively, start stirring, be warming up to 50 ± 5 ℃, after slowly the dropping weight ratio is 30～50% water, stir 30～60min, cooling discharge obtains intermediate.
The preparation of B, focus drive sewage treatment cleaning agent
With weight ratio is 30～60% intermediate, and weight ratio is that 40～70% trihydroxy ethylamine oleate soap places the enamel still that is mixed successively, starts stirring, stirs 30～60min, and discharging obtains focus drive sewage treatment cleaning agent.
Focus drive sewage treatment cleaning agent of the present invention can evenly splash in the pipeline that effluent stream is crossed in the process of disposing of sewage, by the amount of splashing into per hour between 10-50mg.
Beneficial effect of the present invention: focus drive sewage treatment cleaning agent reaches the requirement of re-injection water, oleaginousness≤20mg/L in the water after the processing, suspension content≤20mg/L after drive extraction sewage can being handled.Solve polymer flooding extraction liquid and deviate from sewage obstruction effluent treatment and filtering device problem.Reservoir pressure can be improved in produced-water reinjection stratum after the processing, and the conserve water resource, protection oil field environment.Focus drive sewage treatment cleaning agent of the present invention has the processing efficiency height, and it is less relatively to add dose, and the characteristics that treatment process is stable lower cost of sewage disposal, have improved oilfield economic and social benefit.
