Description
Technical field
The present invention relates to a kind of degreasers for disposing polluted water in oil, and in particular to a kind of polymer drive extraction sewage
Degreaser and preparation method thereof.
Background technique
Polymer displacement of reservoir oil tech has been achieved for preferable oil increasing effect at present.Contain polyacrylamide in polymer displacement of reservoir oil
(PAM), since PAM and emulsifier molecules have similitude, so that there are molecules in system to concentrate on oil-water interfaces by PAM, with
Emulsification molecule is formed together the composite membrane of larger intensity and favorable elasticity.Based on These characteristics, polymer displacement of reservoir oil output sewage
It is higher containing oil index.
With the expansion of polymer displacement of reservoir oil application scale, accompanying problem is that polymer-flooding sewage is handled.Polymer displacement of reservoir oil
Sewage in not only oil content it is high, but also contain a large amount of polymer.The presence of polymer increases the viscosity of water phase, makes water phase
Oily ability enhancing is taken, the difficulty of water-oil separating is increased；Microcosmic test result shows that polymer increases oil-water interfaces intensity,
Interface charge enhancing, causes small oil droplet in recovered water to be stable in the presence of in water body, increases processing difficulty；In addition, polymer
In the presence of the using effect for also disturbing flocculant, flocculation is made to be deteriorated, considerably increases the dosage of medicament；Due to polymer
The adsorptivity of suction-operated, polymer is stronger, and the quantity of sand and mud of carrying increases, and substantially reduces backwashing period.
At present frequently with measure mainly have: 1. physical means polymer-contained sewage.Such technology mainly includes electric dehydration
Technology, " two-stage sedimentation, twice pressure filtration " processing technique and jet air float technology etc.；2. chemical method processing contains
Poly- sewage.Such technology carries out demulsification processing first, and then the medicaments such as further preferably suitable degreaser carry out purification process.
With the deep progress of polymer flooding, the treating capacity of polymer-bearing waste-water is increasing, and ingredient also becomes increasingly complex, this is not
Only increase the difficulty of sewage treatment, also will cause the accelerated ageing of processing equipment, it can be seen that, the processing of polymer-bearing waste-water is oil
The guarantee of field efficient health stable yields.But since ground implementation operation mode is complicated and changeable, sewage composition is caused to have apparent
Regional and timeliness.
Patent ZL201410455664.7 " a kind of degreaser for oil field binary combination flooding output sewage " uses third
Alkene acyloxyethyl dimethyl amine, alkyl chloride, acrylamide, N, N '-methylene-bisacrylamide, ammonium persulfate and sodium sulfite are anti-
It should form, which has dosage few, at low cost, the high feature of oil removal rate, and oil removal efficiency is high, and preparation is simple, at low cost etc.
Feature, but the degreaser belongs to reverse demulsifier, it is poor for the demulsification of emulsion oil-in-water, meanwhile, the degreaser
It is not suitable for the oil removal treatment of polymer-bearing waste-water.
Summary of the invention
The present invention is directed to the deficiency of currently available technology and provides the degreaser and its system of a kind of polymer drive extraction sewage
Preparation Method, which has preparation process simple, low in cost, adaptable, and the feature that deoiling effect is good.
