Abstract
The invention discloses a kind of oil field waste flocculant, its constituent content quality parts ratio is：3 10 parts of aluminium chloride, 25 parts of dilute sulfuric acid, 4 10 parts of sodium tripolyphosphate, 10 14 parts of alkyl benzene sulphonate, 7 12 parts of polyacrylamide, 24 parts of CPAM, 58 parts of deionized water, remaining is water.It the advantage is that：The present invention is applied to oil field waste, the solid suspension and labile organic compound in waste water can be effectively removed, rapid flocculation sedimentation is allowed to, waste water is effectively purified, the organic impurities and oil emulsion contained in oil extraction waste water can be effectively removed, so as to reach the effect of water purification.
Description
Technical field
The present invention relates to oil extraction waste water processing technology field, particularly a kind of oil field waste flocculant.
Background technology
Oilfield sewage is mainly including other types of oil-polluted water in crude oil abjection water, drilling waste water and station.Oilfield sewage
Processing can have various ways according to oil field production, the factor such as environment.When oil field needs water filling, oilfield sewage is after processing
Reinjection into reservoir, now many indexs such as the suspension in water, oil are strictly controlled, prevent it from producing injury to stratum.
Petroleum Production unit is largely focused on arid area, water resource famine, how to become caused sewage in oil recovery process
Waste be changed into values, is of great practical significance.
Using the oil field of water flooding recovery, from the water of water injection well note people's oil reservoir, wherein most is by producing well with crude oil one
Rise return to ground, this part water crude oil outward transport and it is outer it is defeated before must be removed, crude oil, therefore quilt are contained in the sewage of abjection
Referred to as oil field extracted water.With the growth in oilfield exploitation age, the moisture content of water acquisition liquid constantly rises, and some blocks have reached
More than 90%, these oil-polluted waters have turned into the main injection water source in oil field.As oil field Periphery Low Permeability Oilfield and off-balancesheet store up
The continuous exploitation of layer, the requirement to oil-field flooding water quality are stricter.
The content of the invention
It is an object of the invention to provide a kind of solid suspension that can effectively remove in waste water and labile organic compound
Oil field waste flocculant.
The technical solution adopted by the present invention is：
A kind of oil field waste flocculant, its innovative point are：Its constituent content quality parts ratio is：Aluminium chloride 3-10 parts, dilute sulphur
Sour 2-5 parts, sodium tripolyphosphate 4-10 parts, alkyl benzene sulphonate 10-14 parts, polyacrylamide 7-12 parts, CPAM 2-4 parts, deionization
Water 5-8 parts, remaining is water.
Further, its constituent content quality parts ratio is：Aluminium chloride 4-8 parts, dilute sulfuric acid 3-4 parts, sodium tripolyphosphate 6-9
Part, alkyl benzene sulphonate 11-13 parts, polyacrylamide 8-10 parts, CPAM 2-3 parts, deionized water 5-6 parts, remaining is water.
Further, its constituent content quality parts ratio is：6 parts of aluminium chloride, 3 parts of dilute sulfuric acid, 7 parts of sodium tripolyphosphate, alkane
11 parts of base benzene sulfonic acid, 9 parts of polyacrylamide, 3 parts of CPAM, 6 parts of deionized water, remaining is water.
Beneficial effects of the present invention are as follows：
The present invention is applied to oil field waste, can effectively remove solid suspension and labile organic compound in waste water, be allowed to fast
Fast flocculating setting, makes waste water effectively be purified, and can effectively remove the organic impurities contained in oil extraction waste water and emulsification
Oil, so as to reach the effect of water purification.
