Shale reservoir exploration and development is goed deep into, and smooth water consumption is significantly increased, and discharge opeing is returned after pressure and is increased therewith, and rear mineralising is used repeatedly
The accumulative rise of degree, and current existing smooth aqueous systems are only capable of 100,000 below ppm salinities water quality of satisfaction and match somebody with somebody liquid, more high salinity
Performance is greatly reduced under condition of water quality, it is impossible to meet high-salinity water quality construction demand.
Patent 201310216419.6 discloses a kind of repeatable slippery water fracturing fluid utilized of shale oil-gas reservoir, and it is by dropping
Resist, cleanup additive, auxiliary cleanup additive, drop interfacial tension synergist, clay stabilizer, bactericide, antisludging agent and water are constituted.The cunning
Slip water friction reducer can flash-dispersal solution, repeat and utilize, the resistance-reducing yield of slippery water is more than 75%, to temperature, salinity scanning
By force, it is low to water quality requirement.But not to its slippery water salt resistance ability and the resistance-reducing performance in high-salinity brine in its patent
Illustrate.
The A of publication number CN 104371695 patent disclose applied to shale gas batch production pressure break exploit slippery water and
Its preparation method, its slippery water is made up of emulsion friction reducer, bactericide, clay stabilizer, cleanup additive, water.In the slippery water
Emulsion friction reducer dissolves, rises and glue rapidly, and saline-alkaline tolerance is strong.But the patent is only referred to its slippery water in 20000ppm salinities
Thickening property in salt solution.
The A of publication number CN 104403656 patent describes a kind of new type amphoteric ion slippery water fracturing fluid and its preparation
Method, its slippery water fracturing fluid is made up of drag reducer, clay stabilizer, cleanup additive, bactericide, water, and generally with anion
Polyacrylamide " Water-In-Oil " emulsion is compared as the slippery water fracturing fluid of friction reducer, good, unwise to water quality with anti-salt property
Sense, the repeatable advantage such as utilize.But evaluation of the patent to its slippery water anti-salt property is only limitted in the ppm sodium chloride of highest 100,000
Whether there is flocculate generation in salt solution, its resistance-reducing performance in salt solution is not evaluated, it is impossible to illustrate that its friction reducer exists
Whether remain to meet pressing crack construction drop resistance demand in high-salinity brine.
The A of application publication number CN 105482800 patent introduces a kind of slippery water fracturing fluid, and its slippery water fracturing fluid is：
Drag reducer, polyethers, polyethers F68, polyethers P104, perfluorinated octyl sulfuryl amine, sodium salicylate, water composition, with not caused to reservoir
The advantages of injuring, avoid that environmental pollution, drag-reduction effect be good, salt resistance anti-shear ability strong, it is simple to prepare, can be recycled.But should
Patent does not carry out evaluation explanation to its slippery water saline-alkaline tolerance.
The content of the invention
It is an object of the invention to overcome the above mentioned problem that prior art is present there is provided one kind suitable for shale reservoir pressure break
The high salt tolerant drop resistance slippery water of transformation.The present invention realizes use of the slippery water under the conditions of high-salinity water quality, it is adaptable to page
Discharge opeing of returning in rock reservoir fracturing improvement is used repeatedly；Reversed-phase emulsion class friction reducer swelling time is greatly reduced simultaneously,
15s can quick acting in salt solution.
