Abstract
A petroleum sulfonate as compound displacement agent for tertiary recovery of petroleum is prepared through sulfonating the 150-500 SN base oil as raw material coming from oil refinery by use of SO3 gas; extracting by alkyl alcohol according to a wt. proportion of acidic oil; alkyl alcohol=0.5:10; fetching the oil after extracting, dewatering treatment, and then sulfonating again; dissolving the lower-layer liquid in alkyl alcohol extracted by the first and second sulfonations, fully neutralizing and then distillation concentrating to remove alkyl alcohol, and the product is obtained after alkyl alcohol is completely evaporated. It can increase the recovery rate of petroleum by 19-24%.
Description
The present invention relates to a kind of preparation method of the chemically composited oil-displacing agent of oil tertiary recovery with sulfonated petro-leum.
The chemically composited oil-displacing agent of sulfonated petro-leum through being re-dubbed, the oilbearing stratum in injection degeneration oil field can reach the effect that improves oil recovery.Usually adopt alkylbenzene sulfonate as key component in the existing chemically composited oil-displacing agent of oil tertiary recovery, but the raw material ratio of alkylsulfonate is more single, it is narrower to originate, and costs an arm and a leg.
The objective of the invention is to avoid the deficiencies in the prior art part, and provide a kind of raw material extensive, cheap, the process for preparing petroleum sulfonate dedicated for tertiary recovery of petroleum that product quality and performances are comparatively stable.
Can take following technical scheme to realize purpose.
Process for preparing petroleum sulfonate dedicated for tertiary recovery of petroleum, its processing step is:
One, sulfonation is a raw material with the 150-500SN of factory of oil refinery base oil, utilizes SO
3Gas carries out sulfonation;
Two, extracting and separating is made extraction agent with alkyl alcohol, by weight sour oil: alkyl alcohol=0.5～10;
Three, sulfonation for the second time, get collection back oil, processed after, carry out the sulfonation second time;
Four, neutralization concentrates, the lower floor's liquid after the extraction agent extraction sulfonation for the first time and sulfonation for the second time, and in alkyl alcohol, dissolving is back, neutralization fully with the solid inorganic alkali dissolution, and the distillation of neutralization back concentrates, and alkyl alcohol makes the mahogany acid product salt after steaming to the greatest extent.
The relative prior art of the technical program has the following advantages and effect:
The sulfonated petro-leum that this method for making is made can be used as the key ingredient of the chemically composited oil-displacing agent of oil tertiary recovery; Raw materials used wide material sources, cheap, processing method is grasped easily and is controlled, and product quality and performances are comparatively stable; The sulfonated petro-leum that this law is produced is re-dubbed chemically composited oil-displacing agent can form ultra low interfacial tension with the Residual oil in the oilbearing stratum of oil field, reaches 1 * 10
-3MN/m can significantly improve oil recovery, through rock core imitation oil displacement experiment test, improves oil recovery 19-24%, and water-soluble petroleum sulfonic acid salt and oil soluble sulfonated petro-leum have appropriate ratio in the goods; Product performance index: yield 40-70%, sodium content 10-70%, inorganic salt 0-15%, mineral oil 0-40%.
In conjunction with embodiment, technical scheme is described in further detail.
Process for preparing petroleum sulfonate dedicated for tertiary recovery of petroleum, on above-mentioned processing step basis,
One, during sulfonation, gas is dense 1～5%, air dew point-79 ℃, and 20～90 ℃ of sulfonation temperatures, the sulfonation terminal point is controlled at 20～100mgNaoH/g;
Two, during extracting and separating, in liquid distributing device, make sour oil and the alkyl alcohol mixing that fully vibrates to terminal of sulfonation, standing demix then, time of repose 2-14 hour.
Three, during sulfonation for the second time, liquid distributing device is the liquid back oil that promptly comes together at the middle and upper levels, water content 0-10% after processed, temperature 20-80 ℃, the dense 1-5% of gas, air dew point-79 ℃, sulfonation terminal point 10-90mgNaoH/g repeats processing step two then and carries out extracting and separating.
When four, neutralization concentrates, in and carry out in the still, mineral alkali weight concentration 1-10%, control splashes into speed, prevents the heat release concentrations, in and terminal point control PH=5-13, the liquid after the neutralization distills concentrated in still kettle, temperature 60-130 ℃.
Oil can obtain the byproduct white oil after the collection after the secondary sulfonation after the mineral acid pickling, and the white oil viscosity controller is at 30-70mm
2/ S.
