Description
Technical field
The present invention relates to petroleum industry chemicals technical fields more particularly to a kind of clean fracturing fluid and preparation method thereof.
Background technology
Clean fracturing fluid is a kind of a kind of Solid Free fracturing fluid of the surfactant with chemical industry synthesis as thickener,
It can realize at lower viscosities and take sand seam.Clean fracturing fluid with unique rubber breaker manage, in the earth formation meet water or
Broken glue automatically can be realized by meeting oil, and the water not tolerant for being free of water-insoluble after breaking gel or containing is extremely low, counterincision seam surface and sand
The injury of rock permeability is smaller.Therefore, the application effect of clean fracturing fluid is notable.
Currently, the thickening agent (host agent) of clean fracturing fluid is typically by surfactant obtained from chemical industry synthesis, it is main
Agent concentration is higher (5%~7%), therefore leads to that material quantity is big, production cost is higher.Moreover, the gel of clean fracturing fluid is usual
Viscosity at 50 DEG C~60 DEG C suddenly declines, and causes heat resistance poor.Therefore, the higher production cost of clean fracturing fluid
And poor heat resistance, cause the application range of clean fracturing fluid to receive certain limitation.
Invention content
A kind of clean fracturing fluid of present invention offer and preparation method thereof, reduces cost, improves gel and heatproof is cut
Performance is cut, the scope of application of clean fracturing fluid is expanded.
Clean fracturing fluid provided by the invention includes the component of following parts by weight：2~4.5 parts of cationic surfactant,
0.7~1.2 part of septichen sodium, 0.06~0.1 part of 6~9 parts of ammonium chloride, N, N '-di-sec-butyl-p-phenyl enediamine, water 85.2
~91.24 parts.
Wherein, cationic surfactant refers to the surface that hydrophobic group is connected by covalent bond with positively charged hydrophilic group
Activating agent can dissociate the cation with surface-active in aqueous solution.The hydrophobic group of usual cationic surfactant
It is made of the hydroxyl of 8 to 18 carbon, cationic hydrophilic base is by containing the equiatomic group for carrying positive charge of nitrogen phosphate and sulfur or iodine
It constitutes, anionic group is usually single ion or group without surface-active, such as CI-, Br-, Ac-, NO3-.Sun
Ionic surface active agent is in addition to the fundamental property with general surfactant, and cationic surfactant is because hydrophilic group is with just
Charge, and there are some special Interfacial Adsorption performances.
The mechanism of action of the cationic surfactant in fracturing fluid, including it is following aspects：(1) absorption can be selected to obtain
Onto negatively charged microbial inoculum, ion cluster is formed in cell surface, inhibits the function of bacterial membrane, changes the electrical conductance of film, damage
The plasm of evil bacterium, makes natural plant gum class virgin rubber not degrade in the case where placing the long period.(2) it can spread rapidly, soak simultaneously
Oil-water interfaces are adsorbed onto, neutralization interface is electrical, dissolves interfacial film, and the active material in crude oil is made to lose emulsifying capacity.Meanwhile making
The water deviate from emulsion can be assembled, detach quickly.(3) adsorbed film can be formed in gas-liquid or oil-water interfaces, to reduce surface
Or interfacial tension, flow resistance of the liquid in micropore is reduced, liquid is made to be easy to that stratum is discharged.(4) can in clay lattice
Extra negative electrical charge mutually adsorbs, and clay mineral wettability of the surface is made to invert, and forms active agent molecule protective film, prevents moisture
Son enters clay mineral intracell, to reduce the expansion and migration of clay.
Clean fracturing fluid provided by the invention, host agent concentration is low, and production cost is low, and liquid prepares simple, heatproof cutting performance
It is excellent, thus improve the scope of application of clean fracturing fluid.
Optionally, cationic surfactant is cetyl trimethylammonium bromide or octadecyl trimethyl bromination
Ammonium.
In one embodiment, clean fracturing fluid is grouped as by the group of following parts by weight：Cetyl trimethyl bromination
2 parts of ammonium, 0.7 part of septichen sodium, 0.06 part of 6 parts of ammonium chloride, N, N '-di-sec-butyl-p-phenyl enediamine, 91.24 parts of water.
In another embodiment, clean fracturing fluid is grouped as by the group of following parts by weight：Cetyl trimethyl bromine
Change 2.5 parts of ammonium, 0.9 part of septichen sodium, 0.06 part of 7 parts of ammonium chloride, N, N '-di-sec-butyl-p-phenyl enediamine, water 89.54
Part.
In another embodiment, clean fracturing fluid is grouped as by the group of following parts by weight：Octadecyl trimethyl bromine
Change 3 parts of ammonium, 0.9 part of septichen sodium, 0.06 part of 8 parts of ammonium chloride, N, N '-di-sec-butyl-p-phenyl enediamine, 88.04 parts of water.
In another embodiment, clean fracturing fluid is grouped as by the group of following parts by weight：Octadecyl trimethyl bromine
Change 4.5 parts of ammonium, 1.2 parts of septichen sodium, 0.06 part of 9 parts of ammonium chloride, N, N '-di-sec-butyl-p-phenyl enediamine, water 85.24
Part.
Clean fracturing liquid and preparation method thereof provided by the invention, including：
1) water of 85.2~91.24 parts by weight is added in the first container at room temperature；
2) the septichen sodium of 0.7~1.2 parts by weight is added in second container, and is taken from the first container
Second container is added in suitable water, stirs 20min under the speed of 200-300r/min, is configured to a concentration of 10% adjacent hydroxyl
Aqueous sodium benzoate solution；
3) be added in the first container 6~9 parts by weight of ammonium chloride and N, N '-di-sec-butyl-p-phenyl enediamine 0.06~
0.10 parts by weight stir 5min under the speed of 200-300r/min, obtain the first mixture；
4) 2~4.5 parts by weight of cationic surfactant are added in the first container, in the speed of 200-300r/min
