摘要:
The production of hydrocarbons from a subterranean formation is enhanced by use of a well treatment fluid which contains a carboxylated guar which may be prepared by reacting a guar source and a derivatizing agent of the formula X(CH2)nCOOH or alkali salts thereof, wherein X is selected from the group consisting of —OSO2CH3; —OSO2C2H5; —OTs, —Br, and —I and n is between from 1 to 4. The intrinsic viscosity of the carboxylated guar in 2% KCl at 27° C. is at least 750 mL/g and the degree of substitution (DS) of the carboxylated guar is typically between from about 0.02 to about 0.15.
