Description
Technical field
The present invention relates to a kind of oil gas field auxiliary agent technical field, take particularly to a kind of overall process that sand is low to rub
Fracturing fluid of resistance slippery water and its preparation method and application.
Background technology
Oil-gas Layer fracturing (Hydraulic Fracturing), referred to as oil-gas Layer pressure break or pressure break, be
The Technology of one transformation oil-gas Layer seepage characteristic, is a weight of well production increment, water injection well stimulation
Want technological measure, be to utilize ground high-pressure pump group, by high-viscous liquid to exceed the discharge capacity of formation absorption ability
Injecting in well, be formed about high pressure in shaft bottom immediately, this pressure exceedes reservoir stress and rock near shaft bottom
Tensile strength after, form crack in the earth formation, by with proppant liquid inject seam in, make seam to
Front extension, and fill out with proppant, and in fracturing process, the liquid injected into well is referred to as fracturing fluid,
Fracturing fluid is the important component part of fracturing technique, typically the performance requirement to fracturing fluid: viscosity is high, profit
Slip is good, and filter loss is little, and damages without blocking by the fluid layer of pressure break, and convection cell ore deposit is pollution-free, and one
As fracturing fluid have aqueous fracturing fluid, oil base fracturing fluid, emulsus fracturing fluid, foam fracturing fluid and acidic group pressure break
The types such as liquid.
At present, conventional fracturing fluid is mainly with guanidine glue and modifier thereof the aqueous fracturing fluid as thickening agent,
This fracturing fluid is widely applied at each oil gas field, and achieves good effect of increasing production, but along with length
Proposition and the Environmental Protection Situation of celebrating oil gas field " batch production " fracturing work pattern are the severeest, it is desirable to water base pressure
Split liquid in addition to there is Low Damage, low frictional resistance, low cost, the easily row of returning, easily continuously mixture feature, also
Having easily recovery, the feature that recycling rate of waterused is high, to return discharge opeing to environment and soil pollution after reducing pressure
While the amount of conserving water.
But existing with guanidine glue and modifier thereof the fracturing fluid as thickening agent, due to guanidine glue and modifier thereof
Having the putrefactive shortcoming of plant gum and return discharge opeing intractability after breaking gel greatly, cost is high, recycling
Poor feasibility, so the fracturing fluid as thickening agent cannot meet at present " batch production " with guanidine glue and modifier thereof
Construction requirement.
Summary of the invention
The present invention provides a kind of fracturing fluid, solves in prior art with guanidine glue and modifier thereof as thickening agent
Fracturing fluid caused by return discharge opeing intractability big, cost is high, and the technology of recycling poor feasibility is asked
Topic, and this fracturing fluid can meet " batch production " pressure break very well and make while can alleviating environmental protection pressure break
Industry requirement.
The present invention also provides for the preparation method of a kind of fracturing fluid, simple to operate easily controllable in preparation process,
The fracturing fluid being prepared from is the most corrupt, heat-resistant salt-resistant, rises viscous fast, meet continuous mixture requirement in water,
This fracturing fluid thickener has good Efficient Adhesive Promotion, and in good time its concentration of adjustment just can realize fall and block water
With load fluid function.
The present invention provides the application in oil-gas Layer pressure break of a kind of fracturing fluid, the increasing comprised due to this fracturing fluid
Thick dose is generated, in oil-gas Layer by acrylamide, acrylic acid and alkylphenol polyoxyethylene acrylate reactions
In pressure break during application, the row's of returning liquor treating process of this fracturing fluid is simple, cost is extremely low, recycling rate of waterused is high,
" batch production " fracturing work requirement can be met very well while alleviating environmental protection pressure break.
The present invention provides a kind of fracturing fluid, and the mass percent of described fracturing fluid consists of: thickening agent
0.10%-0.45%, clay stabilizer 0.35%-0.55%, surfactant 0.3%-0.5% and the water of surplus,
Wherein, described thickening agent by acrylamide, unsaturated carboxylic acid, alkyl phenol Polyoxyalkylene ethers unsaturated acid ester,
The reaction of N, N-dimethyl-alkyl tertiary amine, halo cyclic ethers generates, and described acrylamide, described unsaturation
Carboxylic acid, described alkyl phenol Polyoxyalkylene ethers unsaturated acid ester, described N, N-dimethyl-alkyl tertiary amine and described
The mol ratio of halo cyclic ethers is 99:25:1:1:1.
In the fracturing fluid that the present invention provides, including thickening agent, clay stabilizer, surfactant and water,
Wherein thickening agent is acrylamide, unsaturated carboxylic acid, alkyl phenol Polyoxyalkylene ethers unsaturated acid ester, N, N-
The copolymer that the reaction of dimethyl-alkyl tertiary amine, halo cyclic ethers generates, owing to after fracturing liquid rubber-breaking, residue is to make
Become the injury of substrate seepage flow rate and the major reason of proppant pack flow conductivity injury, in prior art,
When fracturing fluid is with guanidine glue and modifier thereof for thickening agent, return discharge opeing intractability after fracturing liquid rubber-breaking big, become
This height, recycling feasibility is poor, and in the present invention, the thickening agent of use be by acrylamide, no
Saturated carboxylic acid, alkyl phenol Polyoxyalkylene ethers unsaturated acid ester, N, N-dimethyl-alkyl tertiary amine, halo cyclic ethers
The copolymer that reaction generates, the fracturing fluid recovery (backflow) of formation is effective, can realize without fast under the conditions of liquid nitrogen companion's note
Speed returns row, meanwhile, returns discharge opeing recovery process simple, and utilization rate is high, it is only necessary to does simple filtration and processes i.e.
Reusable, in the present invention, acrylamide, unsaturated carboxylic acid, alkyl phenol Polyoxyalkylene ethers unsaturated acids
Ester, N, when the reaction of N-dimethyl-alkyl tertiary amine, halo cyclic ethers generates thickening agent, in the present embodiment, institute
State acrylamide, described unsaturated carboxylic acid, described alkyl phenol Polyoxyalkylene ethers unsaturated acid ester, described N,
N-dimethyl-alkyl tertiary amine and described halo cyclic ethers are anti-for 99:25:1:1:1 mixing according to mole hundred ratios
Should generate thickening agent, in the present invention, this thickening agent mass percent in fracturing fluid is 0.10%-0.45%,
The mass percent of such as thickening agent can be 0.15%, 0.20%, 0.25%, 0.35% or 0.40%, tool
