摘要:
The present invention relates to a liquefied polymer fracturing fluid thickener, which has evaluation indexes as: a density of 1.0-1.3 g/cm3; a gelling time less than or equal to 15 s; and a viscosity of its 1.0% solution greater than or equal to 30 mPa·s. The present invention also relates to a method for preparing said liquefied polymer fracturing fluid thickener.
摘要:
The present invention relates to a Clean Fracturing Fluid Thickener of Multi-block Associative Copolymer (APCF) and a method preparing thereof. Said Copolymer has evaluating indicators as: (1), the viscosity of its 0.3% water solution at 20° C.≧30 mPa·s; (2), the viscosity of said solution after gel breaking≦5 mPa·s; and, (3) a static sand-suspending time of said solution≧10 min.
