The present invention provides a kind of slippery water fracturing fluid, is composed of the following parts by weight: 0.03-0.18 parts of biopolymer friction reducer, 0.12-0.28 parts of clay stabilizer, 0.03-0.18 parts of cleanup additive, 0.00003-0.00018 parts of gel breaker and 99-100 parts of water.Preferably, the slippery water fracturing fluid is composed of the following parts by weight: 0.05-0.15 parts of biopolymer friction reducer, 0.15-0.25 parts of clay stabilizer, 0.05-0.15 parts of cleanup additive, 0.00005-0.00015 parts of gel breaker and 99-100 parts of water, the slippery water fracturing fluid liquid returns row and leads height, the biodegradability of the row's of returning object is high, it is low to return drain salinity, it is low to return drain fluorine content, low to reservoir Low Damage, environment friendly is high.
Description
Technical field
The invention belongs to oil exploitation fracturing fluid fields, and in particular to a kind of slippery water fracturing fluid.
Background technique
Shale gas refers to the Unconventional gas preserved in series of rocks based on preservation Yu Yifu organic shale, is continuous
The mixing of the biochemical genesis air and heat origin cause of formation gas of generation or both, can be present in intrinsic fracture and hole with free state,
It is present in kerogen, clay particle surface with ADSORPTION STATE, there are also minute quantities to be stored in kerogen and asphalitine with dissolved state
In, free gas ratio is generally 20%~85%.Using more segment level wells and slippery water fracturing fluid as the extensive volume of representative
Fracture technology obtains huge business success in, in the shale gas exploitation of beautiful and some other countries and regions.
It is carried out in shale gas development process using fracturing fluid, for the performance for improving slippery water fracturing fluid, it usually needs
A certain amount of additive, such as friction reducer, clay stabilizer are wherein added, however, the improperly use of chemical addition agent,
Serious reservoir damage also is caused to stratum while establishing seam net system, is such as made using polyacrylamide and its derivative
For pressure break friction reducer, because it is easily adsorbed in reservoir clay mineral surface, forms filter cake etc., it is difficult to remove；On the other hand, page
The transformation of rock gas reservoir, it is huge to be denounced by environmentalist always with water scale, largely return the addition of chemistry contained in drain
Agent causes tremendous influence to environment, shows: 1) soil texture influence original can be changed by returning the polyacrylamide in drain
Biology, the existence of microorganism, and change plant growth by changing root system of plant microenvironment；2) remaining acrylamide
Monomer mainly causes serious nerve, reproduction and development toxicity；3) use of a large amount of potassium chloride leads to the row of returning in clay stabilizer
Liquid salinity greatly improves, and influences earth's surface water salinity, causes saline Land；4) fluorine-containing surfactant in cleanup additive
It uses, so that fluorine increases extremely in soil and water body environment, is caused based on human teeth and bone by bioaccumulation
Systemic chronic lesion.Therefore, slippery water fracturing fluid in the prior art would generally generate shale gas reservoir and ambient enviroment
Compared with havoc.
Summary of the invention
It is low to the injury of shale gas reservoir the technical problem to be solved by the present invention is to provide a kind of slippery water fracturing fluid, and not
It will cause environmental damage.
To solve the above-mentioned problems, the present invention provides a kind of slippery water fracturing fluid, is grouped by the group of following parts by weight
At:
0.03-0.18 parts of biopolymer friction reducer, 0.12-0.28 parts of clay stabilizer, 0.03-0.18 parts
Cleanup additive, 0.00003-0.00018 parts of gel breaker and 99-100 parts of water.
Wherein, biopolymer friction reducer refers to from extracting in biomaterial (such as plant, animal material), degradable
Hydrocarbon high molecular polymer, such as various biological sources polysaccharide, natural plant, cellulose etc..Clay stabilizer
Also known as clay expansion-resisting agent can carry out Antiswelling Treatment to clay mineral, prevent clay mineral because of formation rock caused by hydration swelling
The phenomenon that stone strength reduction and blocking rock interior gap and venturi, prevent the irreversible decline of reservoir permeability.
In technical solution, it is preferred that the slippery water fracturing fluid is composed of the following parts by weight:
0.05-0.15 parts of biopolymer friction reducer, 0.15-0.25 parts of clay stabilizer, 0.05-0.15 parts
Cleanup additive, 0.00005-0.00015 parts of gel breaker and 99-100 parts of water.
In technical solution, it is preferred that the slippery water fracturing fluid is composed of the following parts by weight:
0.10 part of biopolymer friction reducer, 0.20 part of clay stabilizer, 0.10 part of cleanup additive, 0.0001 part
Gel breaker and 99.5999 parts of water.
In technical solution, it is preferred that biopolymer friction reducer is natural plant gum, cellulose derivative, in starch derivatives
It is one or more.Wherein, natural plant gum includes but is not limited to guar gum, fenugreek gum, sesbania gum, konjac glucomannan, flax gum, fiber
Plain derivative includes but is not limited to hydroxyethyl cellulose, and starch derivatives includes but is not limited to carboxymethyl starch.
Biopolymer friction reducer has good resistance-reducing performance, can satisfy reduction pumping frictional resistance, improves injection discharge capacity
Purpose；It can be saccharide compound in natural degradation under reservoir conditions, to storage from boiomacromolecule and its derivative
Layer is injured without long-term water conservancy diversion, so as to effectively improve the production capacity of unconventional oil and gas.
In technical solution, it is preferred that natural plant gum is one of guar gum, fenugreek gum, sesbania gum, konjac glucomannan or a variety of.
In technical solution, it is preferred that biopolymer friction reducer is the mixture of guar gum and sesbania gum.It is furthermore preferred that
Biopolymer friction reducer mixes the mixture formed with sesbania gum for guar gum with the mass ratio of 5:1.The phase of biopolymer
Bigger to molecular weight, viscosity is bigger, and resistance-reducing performance is higher, but its difficulty of degrading increases, and guar gum has very big opposite point
Son amount, resistance-reducing performance is high, but degradation difficulty is big, and sesbania gum is small compared to guar gum relative molecular weight, and resistance-reducing performance is slightly lower, but
Natural degradation is easier, and the two is cooperated and can get optimal drop resistance using the mixing of the mass ratio of 5:1 as friction reducer in slippery water
Performance and natural degradation performance.
