Description
Technical field
The invention belongs to the preparing technical field of oil field chemical, is related to a kind of inorganic agent and its system for oilfield sump oil
Preparation Method.
Background technology
Can produce substantial amounts of sump oil during oilfield exploitation and production, including oil well pipe leakage and ground crude oil, by
Water treatment agent, demulsifier and sump oil of colloidal bitumen soil emulsification etc. caused by the chemical agent of various measure operations are added, is led to
These normal contaminated oils are collected in contaminated-oil basin or slop tank.The characteristics of this kind of sump oil is that emulsibility is high, water content is big, and is contained
Heavy constituent and the soil such as higher colloid, asphalitine, dehydration difficulty is high, is mainly manifested in：(1) because water content is high, using
During existing process dehydration, the demulsifier dosage used is multiplied and effect is bad；(2) sump oil produces at oil-water interfaces
Raw stable thick emulsion layer, the interfacial film of difficult demulsification is formed, cause conventional demulsifier to meet that the dehydration of this kind of sump oil will
Ask；(3) due to containing heavy constituent and the soil such as higher colloid, asphalitine in sump oil, complicated component, conventional demulsifier can not
Effectively the crude oil in sump oil is separated.
Oilfield sump oil such as without rationally effective processing, can not only waste petroleum resources, also environment can be caused seriously
Pollution.With the pay attention to day by day of Environmental protection work, it is also increasingly stricter to recycle the requirement of sump oil, therefore how
Efficiently, economic processing sump oil turns into the severe challenge that current oil field faces.The skill of processing sump oil well known in the art at present
Art mainly has resource reclaim, harmless treatment, adds demulsifier and comprehensive utilization technique etc..In every technology, because chemistry is broken
The advantages that emulsion is active high, quick, therefore it has been the most frequently used sump oil processing method in current this area to add demulsifier.But
At present for conventional demulsifier known to market mainly also all there is crude oil recovery rate it is low, dehydration it is difficult the shortcomings of, such as publication number
A kind of method for treating ageing oil of viscous oil is disclosed for CN102041038A Chinese patent application text, the patented technology carries first
A kind of viscous crude ageing oil being mixed to prepare by phenol, styrene, polyethylene polyamine, formaldehyde, oxirane and expoxy propane is supplied
With demulsifier, though this demulsifier has preferably demulsification function, the destruction for oil-water interfacial film can be realized, its biology
Degradability is poor, big to the subsequent affect of environment.In addition, go back a kind of existing phenomenon in the special enterprise at home in this area at present
It is：Many oil fields do not handle sump oil directly generally at the scene, but oil-containing sump oil is sold into sump oil in a manner of discarded object and returned
Receipts company, this will not only pay the substantial amounts of sump oil handling of recovery company and freight, also result in substantial amounts of crude oil every year
Secondary use can not be reclaimed.
The content of the invention
The problem of it is an object of the invention to exist to prior art, solves, there is provided a kind of inorganic agent of oilfield sump oil
And preparation method thereof, the inorganic agent have it is good to sump oil demulsification, production cost is low, preparation method is easy, oil recovery rate is high
And the advantages that having a wide range of application, oil in sump oil, water, mud three phase separation can be effectively realized.
To solve above technical problem, the present invention adopts the following technical scheme that：
A kind of inorganic agent for oilfield sump oil, based on weight/mass percentage composition, the inorganic agent is made up of following ingredients：
In the above-mentioned inorganic agent for oilfield sump oil, sulfonic acid and/or its salt are sulfonic acid, DBSA, dodecane
One or more in base benzene sulfonic acid sodium salt, alpha-alkene sulfonate.
In the above-mentioned inorganic agent for oilfield sump oil, APG APG0810, APG1214, APG0814, APG0816,
One or more in APG1216.
In the above-mentioned inorganic agent for oilfield sump oil, solvent is the one or more in methanol, ethanol, glycerine or water.
In prescription of the present invention, sulfonic acid and/or its salt belong to detergent-dispersant additive class material, have dewatering speed it is fast, to sump oil
The advantages of peace and quiet effect is good；APG strong detergency, can be with any types surfactant compound, so as to effectively go oil removing
Soil and greasy dirt in the sump oil of field；Penetrant t can significantly reduce surface tension, permeate Quick uniform, reach increase abjection water
Purpose；It is flocculation, purification, decolouring that dimethyl diallyl ammonium chloride manages the main function played in agent in this place, and it is simultaneously
Also there is good sludge stripping effect and certain scattered, osmosis, so as to purify the water quality of abjection water.
Method for preparing above-mentioned inorganic agent is：By formula by solvent, sulfonic acid and/or its salt, APG, bleeding agent
T, dimethyl diallyl ammonium chloride is mixed, and is stirred 30~60min under conditions of being 30 DEG C~50 DEG C in temperature, that is, is obtained
Described inorganic agent.
Compared with prior art, the beneficial effects of the invention are as follows：A variety of surface reactive materials are used in the treatment agent formula
With with can make the bad stability of emulsion in sump oil, reach the purpose of demulsification, water-oil separating, so as to effectively by sump oil
Crude oil separate, realize dehydration, de- slag and recovery crude oil.Product of the present invention is especially suitable for water content more than 15%
The processing of various sump oils caused by oil emulsion and oil exploitation process in tank bottom sump oil, settling tank, crude oil recovery rate is high, subtracts
Lack pollution of the sump oil to the Nature, further increase the economic benefit of oil field production.
