Abstract
The invention relates to an amphoteric surfactant fracturing fluid and a preparation method thereof, wherein the amphoteric surfactant fracturing fluid comprises 3-5% of amphoteric surfactant, 0.5-1% of anionic surfactant, 2-4% of inorganic salt, 0.3-0.5% of low molecular alcohol, 0-5% of pH value regulator, 0.5% of clay stabilizer and the balance of water by mass percent; firstly, adding an amphoteric surfactant, an anionic surfactant, low molecular alcohol, a pH value regulator and a clay stabilizer into water, stirring for 5-10min to obtain uniform and stable suspension, adding an inorganic salt, and stirring for 1-2min to obtain a fluid with good viscoelasticity; the amphoteric surfactant fracturing fluid is used for oil-gas field fracturing at the formation temperature of 60-80 ℃, has no residues after gel breaking, and does not damage the formation.
Description
Technical field
A kind of fracturing liquid that the present invention relates to waterfrac treatment well stimulation in a kind of exploitation of oil-gas field process, is specifically related to a kind of amphoterics fracturing liquid and preparation method thereof.
Background technology
Pressure break has been developed rapidly and widespread use as the Main Yield-increasing measure of low-permeability oil gas reservoir, and fracturing liquid is the important component part of fracturing technique.Both at home and abroad the most frequently used fracturing liquid is mainly to take the aqueous fracturing fluid that natural plant, Mierocrystalline cellulose and synthetic polymer be viscosifying agent, and Yi Ge oil field is widely applied at present, and has obtained good effect of increasing production.But it is incomplete that the defect of aqueous-based polymers fracturing fluid system is fracturing liquid rubber-breaking, and after broken glue, residue can stop up blowhole and crack, reduce crack support belt flow conductivity and hydrocarbon zone rate of permeation, thereby greatly reduce fracturing effect, cause fracturing yield increasing effect can not reach best.
Summary of the invention
The object of the invention is to provide a kind of fracturing liquid based on amphoterics and preparation method thereof, in amphoterics molecule, contain positively charged ion and anionic hydrophilic base, attraction between zwitterion impels surfactant molecule to arrange closely, in salts solution under different pH values or acid solution, can form the micella gel of varying strength, available its prepared the working fluid of multiple excellent property, do not need linking agent, gel breaker and other chemical additive, fracturing fluid residue content is almost nil, therefore without formation damage, also can make filling bed keep good flow conductivity, the more effective raising Oil & Gas Productivity of energy, fully reach the object of well fracturing.
Amphoterics fracturing liquid of the present invention, comprises amphoterics 3%-5% by mass percentage, anion surfactant 0.5%-1%, inorganic salt 2%-4%, low mass molecule alcohol 0.3%-0.5%, pH value conditioning agent 0%-5%, clay stabilizer 0.5%, all the other are water.
The of the fracturing fluid preparation method of described amphoterics is divided into two steps, first amphoterics, anion surfactant, low mass molecule alcohol, pH value conditioning agent and clay stabilizer are added to the water by certain mass percent, stir 5-10min, obtain the suspension liquid of stable homogeneous, add again inorganic salt, after stirring 1-2min, obtain having the fluid of good viscoelasticity.
Amphoterics of the present invention is octadecyl betaine, octodecyl betaine, amine hydroxybenzene CAB or erucicamide CAB.Described anion surfactant is methyl sodiosul foaliphatate or disodium 4-dodecyl-2,4 '-oxydibenzenesulfonate.Described inorganic salt are sodium-chlor.Described low mass molecule alcohol is methyl alcohol or ethanol.Described pH value conditioning agent is formic acid.Described clay stabilizer is Repone K.
Amphoterics fracturing liquid of the present invention, adopting amphoterics is main viscosifying agent, anion surfactant is auxiliary viscosifying agent, inorganic salt are gel promotor, can form viscoelastic fluid in multiviscosisty under different pH condition, obtain amphoterics fracturing liquid.Amphoterics fracturing liquid prepared by the present invention have low-viscosity, snappiness, low frictional resistance, height take sand, effectively control seam high, increase in the advantage ， stratum such as seam is long and can break glue with oil, gas, after broken glue, without residue, do not injure stratum.
Surfactant fracturing fluid prepared by the present invention is through Lab-evaluation: temperature resistant capability can reach more than 60 ℃, be better than other clean fracturing liquid system, by 1: 1, add water (or hydro carbons) both can thoroughly break glue, final breaking glue solution viscosity is less than 5mPa.S, system breaking glue solution surface tension value is 23.59mN/m, interfacial tension value is 1.03mN/m, and explanation system has the good row's of returning performance.
