CLEAN FRACTURING FLUID THICKENER OF MULTI-BLOCK ASSOCIATIVE COPOLYMER (APCF) AND METHOD PREPARING THEREOF
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.
