Abstract
The invention relates to a compound adjustment method of petroleum sulfonate, which provides a petroleum sulfonate compounded system for oil displacement, which ensures that lamination does not occur when a product is laid within 30 days at normal temperature and a preparation method of the petroleum sulfonate compounded system. The system takes petroleum distillate oil as raw material, takes gaseous sulfur trioxide, liquid sulfur trioxide or fuming sulfuric acid as sulfonating agent, takes petroleum sulfonate, the active matter content of which is larger than 28 percent, formed by neutralizing ammonia or sodium hydroxide as a base, and is formed by adding dodecyl benzene sulfonic acid, heavy alkyl benzene sulfonic acid, alpha-olefin sulfonic acid, alkali or water. The system comprises the following components by mass: 40 to 90 percent of petroleum sulfonate, 0 to 20 percent of dodecyl benzene sulfonic acid, 0 to 20 percent of heavy alkyl benzene sulfonic acid, 0 to 10 percent of alpha-olefin sulfoacid, 0 to 30 percent of alkali and 0 to 40 percent of water. By adopting the technical scheme, the adaptability of petroleum sulfonate products in an oil field is improved, the product stabilizing capacity is enhanced, and the production process of the petroleum sulfonate is simplified.
Description
Technical field
The present invention relates to the compound adjustment method of the sulfonated petro-leum in a kind of tertiary oil production in oil field field, especially a kind of displacement of reservoir oil is with sulfonated petro-leum compound system and preparation method thereof.
Background technology
Sulfonated petro-leum is to be the AS of raw material production with the fraction oil of petroleum, and is good with the resident fluid compatibleness because raw material sources are wide, become the displacement of reservoir oil important in the tertiary oil production in oil field and used agent.Production technique to sulfonated petro-leum has had more research at present; The method of 150～580 ℃ of raw oils of the continuous sulfonation of CN1472199A; The method of 200～550 ℃ of distillates of CN101318112A hypergravity sulfonation; Because contain a large amount of unsulfonated oils in the product, product stability is poor, demixing phenomenon very easily occurs.CN1275431A has reported the method for 320～380 ℃ of fraction oil of petroleum of membrane-type sulfonation; The method of 380～520 ℃ of distillates of three grades of pot group type sulfonation of CN1327979A; Carry out the sulfonated method behind 200～500 ℃ of distillate methods of CN1203935A sulfonation, the CN102190604A hydrotreated feed oil; In these methods, all increased pure water extraction measure,, made production technique more complicated though improved product active matter content and product stability.Owing to the difference of raw materials used oil and process for sulfonation, bring the difference of product performance, simultaneously, because the change of oil field block water quality, crude oil composition makes product application receive very big restriction.CN101455950A adopts 200～500 ℃ of distillates to mix the method for back sulfonation production sulfonated petro-leum with heavy alkyl benzene; Though improved the flexibility and the stabilizing power of sulfonated petro-leum to a certain extent; But; Make product meet the oil field requirement fully, need advance bigger adjustment to starting material, proportioning, processing parameter etc., the production control difficulty is big, product percent of pass is low.CN1865392A is the method that host prepares the TOR oil-displacing agent with the sulfonated petro-leum; But the AS that adopts mainly exists with solid-state; Need configuration separately to use; And need to use nonionogenic tenside, solvent, sodium-chlor etc., the equipment that takies is many, production process is complicated.
Summary of the invention
The object of the invention just provides a kind of product normal temperature and places in 30 days demixing phenomenon does not take place, and the displacement of reservoir oil that stabilizing power improves is with sulfonated petro-leum compound system and preparation method thereof.Technical scheme is to be raw material with the fraction oil of petroleum; With gaseous sulfur trioxide, liquid sulphur trioxide or oleum is sulphonating agent; The active matter content that employing ammoniacal liquor or sodium hydroxide neutralization obtain is the basis greater than 28% sulfonated petro-leum, forms through adding Witco 1298 Soft Acid, heavy alkylbenzene sulfonic acid, terminal olefin sulfonic acid, alkali or water.
Each constituent mass per-cent is following: sulfonated petro-leum: 40%～90%; Witco 1298 Soft Acid: 0～20%; Heavy alkylbenzene sulfonic acid: 0～20%; Terminal olefin sulfonic acid: 0-10%; Alkali: 0～30%; Water: 0%～40%.Alkali is mainly one or more in ammoniacal liquor, sodium hydroxide, methylamine solution or ethamine, diethylamine, monoethanolamine, diethylolamine, the trolamine, is mainly used in to regulate product P H value, improves the product dissolution dispersity.Water is mainly used in the viscosity of regulating product, guarantees the flowability of product under normal temperature condition.Working method: in sulfonated petro-leum, add Witco 1298 Soft Acid, heavy alkylbenzene sulfonic acid or terminal olefin sulfonic acid in proportion with crude oil fractions oil sulfonation production; Fully stirred 1～3 hour; Under agitation condition, add needed alkali gradually, pH value is reached between 7～9, and then add institute's water requirement; The pH value that is stirred well to top and the bottom product in the reaction kettle is consistent, is sulfonated petro-leum flooding system product.After adopting technique scheme, improved the flexibility of mahogany acid product salt, strengthened the product stabilizing power, simplified the mahogany acid technology of threonates in the oil field.1) need not adjust, promptly can produce the mahogany acid product salt that satisfies oil field displacement of reservoir oil requirement existing mahogany acid technology of threonates; 2) the promoting agent product that relates to buying is all liquid sulfonated product, and active constituent content is high, and is easy to use, good with the main product compatibleness; 3) relate to raw material and be all commercially available Chemicals, raw material is easy to get; 4) produce preparation simply, easy handling, production cost is low.
