摘要：
The present invention relates to methods, aqueous treating fluids and friction pressure reducers for the treating fluids. A treating fluid of the invention comprises water and a non-toxic environmentally acceptable friction pressure reducer comprising a mixture of a copolymer of acrylamide and dimethylaminoethyl acrylate quaternized with benzyl chloride and a stabilizing and dispersing homopolymer of ethanaminium,N,N,N-trimethyl-2-[(1,oxo-2-prbpenyl)oxy]-chloride.
