Abstract
The invention relates to a method for preparing a thickened oil viscosity reducer based on gutter oil as a raw material. The method comprises the following steps of carrying out amidation reaction on gutter oil which is rich in source and is enriched in triglyceride and N,N-dimethyl-1,3-propanediamine to produce oleamide having terminal groups containing tertiary amide and reacting bimolecular oleamide having terminal groups containing tertiary amide with monomolecular 1,4-butanediol diglycidyl ether to produce Gemini amphiphilic molecules containing quaternary ammonium ions. The compound has thickened oil emulsifying capability. The preparation method is simple and low in cost and provides a new way to treat gutter oil.
Description
Technical field
The invention belongs to oilfield oil extraction additive field, particularly relating to a kind of is that raw material is to prepare the method for heavy crude thinner with sewer oil.
Background technology
In recent years, the most oil field of China has entered the tail period stage, along with the continuous increase of viscous oil recovery amount, highly dense, high characteristic that is sticky, poor fluidity brings extreme difficulties to Oil extraction and conveying, and the key of heavy oil development is how to reduce viscosity of crude, improves the aspects such as its mobility.Although existing various viscosity-depression agent, still needs cost lower in field produces in prior art, stable performance and effective viscosity-depression agent.
Sewer oil is the inedible oil of quality, health extreme difference, the index severe overweights such as peroxide value, acid value, moisture, carbonyl valency, mda.The raw material of China's sewer oil is sufficient, produces at least about 5,000,000 tons every year, is rich in triglyceride level.
The present invention is with the sewer oil of abundance for raw material, and the viscosity-depression agent of preparation can be penetrated in crude oil by water-oil interface by aqueous phase, and weakens the intermolecular reactive force of crude oil, thus reduces viscosity of crude, increases the mobility of crude oil in stratum.
Summary of the invention
The present invention take sewer oil as raw material, itself and N, N-dimethyl-1,3-propylene diamine is reacted, then reacts with ethylene glycol diglycidylether, generates the oleylamide of end group containing tertiary amine; Then two exposed terminated groupses react with the BDDE of a part containing the oleylamide of tertiary amine again, generate the double type amphiphile, amphiphilic molecule containing quaternary amine ion.This compounds has emulsification viscous crude ability.Preparation method's technique is simple, with low cost, and provides a kind of new way of processing and utilizing sewer oil.
