Description
Technical field
The present invention relates to clean fracturing fluid prepared by a kind of new clean fracturing liquid system and preparation method thereof, the present invention
Suitable for the exploration and development of routine and unconventional petroleum resources.
Background technology
A kind of well stimulation of the hydraulic fracturing as oil-gas reservoir, using nearly 50 years, it be using higher discharge capacity and
Pressure, by under the non newtonian high viscosity fracturing fluid injection well containing high concentration proppant, seam is made in target zone to realize, and extend expansion
Open up crack.During the exploration and development of oil-gas reservoir, some low permeability reservoirs can be usually found, Guar is used to such reservoir
The polymer fracturing fluid such as glue system carries out fracturing reform, not only can leave part residue in stratum and supporting crack, can also draw
Expanding, being scattered with migrating for stratum CLAY MINERALS AND THEIR SIGNIFICANCE is played, larger injury is caused to reservoir.To improve the effect of pressure break, reduce
Injury to reservoir is, it is necessary to develop the clean fracturing liquid system of low residue.
Viscoelastic surfactant clean fracturing fluid（VES）It is that one kind can form flexibility in the aqueous solution under certain condition
Rod-shaped micelle is simultaneously mutually wound reversible three-dimensional space net structure and surface goes out the surfactant of special rheological property
Solution system, all in all, VES fracturing fluids have easy preparation, construction is simple, dosage is few, frictional resistance is small, prop-carrying capacity is strong, returns
Row is easy, and what is more important VES injures small without residue, to caused by stratum or underground after breaking gel, it is not necessary to enzyme or oxidation
Agent reduces viscosity, and optimum viscosity can be more quickly formed in easy aquation so that whole fracturing work become it is simple efficiently.
