Description

A kind of inorganic agent for oilfield sump oil and preparation method thereof
Technical field
The invention belongs to the preparing technical field of oil field chemical, relate to a kind of inorganic agent for oilfield sump oil and system thereof Preparation Method.
Background technology
Oilfield exploitation and produce during can produce substantial amounts of sump oil, leak outside including oil well pipe and ground crude oil, by The sump oil etc. of the colloidal bitumen earth emulsifying that the chemical agent of addition water treatment agent, demulsifier and various measure operation causes is logical Often these contaminated oil are collected in contaminated-oil basin or slop tank.The feature of this kind of sump oil is that emulsibility is high, water content is big, and contains Heavy constituent and the earth such as higher colloid, asphalitine, dehydration difficulty is high, is mainly manifested in: (1) is high due to water content, is using During the dehydration of existing process, the demulsifier consumption of use is multiplied and effect is bad;(2) sump oil produces at oil-water interfaces Raw stable thick emulsion layer, forms the interfacial film of difficult breakdown of emulsion, and the dehydration causing the demulsifier of routine can not meet this kind of sump oil is wanted Ask;(3) due in sump oil containing heavy constituent and the earth such as higher colloid, asphalitine, complicated component, conventional demulsifier can not Effectively by the crude separation in sump oil out.
Oilfield sump oil, if do not carried out the most effective process, not only can be wasted petroleum resources, also can cause environment seriously Pollute.Along with the pay attention to day by day of Environmental protection work, the requirement of recycling sump oil is stricter the most how Efficiently, the economic sump oil that processes has become the severe challenge that current oil field faces.The skill of current process sump oil well known in the art Art mainly has resource reclaim, harmless treatment, adds demulsifier and comprehensive utilization technique etc..In every technology, owing to chemistry breaks The advantages such as the active height of Emulsion, instant effect, therefore adding demulsifier has been the most frequently used sump oil processing method in current this area.But Conventional demulsifier known to market the most all also exists the shortcomings such as low, the dehydration difficulty of crude oil recovery rate at present, such as publication number Chinese patent application text for CN102041038A discloses a kind of method for treating ageing oil of viscous oil, and first this patented technology carries Supply a kind of viscous crude ageing oil being mixed to prepare by phenol, styrene, polyethylene polyamine, formaldehyde, oxirane and expoxy propane With demulsifier, though this demulsifier has preferable breakdown of emulsion function, it is possible to realize the destruction for oil-water interfacial film, but it is biological Degradability is poor, big to the subsequent affect of environment.Additionally, a kind of phenomenon that there is also in current this area enterprise the most at home It is: a lot of oil fields generally the most directly process sump oil, but in the way of garbage, oil-containing sump oil are sold to sump oil and return Receipts company, this recovery company to be paid substantial amounts of sump oil handling and freight, also result in substantial amounts of crude oil Secondary cannot be reclaimed use.
Summary of the invention
The problem that it is an object of the invention to there is prior art is solved, it is provided that the inorganic agent of a kind of oilfield sump oil And preparation method thereof, that this inorganic agent has is good to sump oil demulsification, production cost is low, preparation method is easy, oil recovery rate is high And the advantage such as applied range, oil in sump oil, water, mud three phase separation can be effectively realized.
For solving 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, described inorganic agent is made up of following ingredients:
Above-mentioned in the inorganic agent of 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.
Above-mentioned in the inorganic agent of oilfield sump oil, alkyl polyglucoside is APG0810, APG1214, APG0814, APG0816, One or more in APG1216.
Above-mentioned in the inorganic agent of oilfield sump oil, solvent is one or more in methanol, ethanol, glycerol or water.
In prescription of the present invention, sulfonic acid and/or its salt belong to detergent-dispersant additive class material, have dewatering speed fast, to sump oil Peace and quiet effective advantage;Alkyl polyglucoside strong detergency, can compound with any classes of surfactant, thus effectively go oil removing Earth in the sump oil of field and greasy dirt;Penetrant t can significantly reduce surface tension, permeates Quick uniform, reaches to increase the abjection water yield Purpose;It is to flocculate, purify, decolour 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 dispersion, osmosis, thus purify the water quality of abjection water.
For preparing the method for above-mentioned inorganic agent it is: by formula by solvent, sulfonic acid and/or its salt, alkyl polyglucoside, penetrating agent T, dimethyl diallyl ammonium chloride are mixed, and stir 30~60min, i.e. obtain under conditions of temperature is 30 DEG C~50 DEG C Described inorganic agent.
Compared with prior art, the invention has the beneficial effects as follows: this treatment agent formula uses kinds of surface active substance Join and, the bad stability of emulsion in sump oil can be made, reach the purpose of breakdown of emulsion, oil-water separation, thus effectively by sump oil Crude separation out, it is achieved be dehydrated, de-slag and reclaim crude oil.Product of the present invention is particularly well-suited to water content more than 15% Oil emulsion in tank bottoms sump oil, settling tank and the various dirty oil handling of oil exploitation process generation, crude oil recovery rate is high, subtracts Lack the sump oil pollution to the Nature, further increase the economic benefit that oil field produces.
