摘要：To improve the viscosity of carboxymethyl hydroxyethyl cellulose (CMHEC) solution and broaden its application, sodium trimetaphosphate (STMP) was used to modify CMHEC to obtain water-soluble STMP-CMHEC for the first time. The STMP-CMHEC solution shows better viscous performance than CMHEC solution. For the concentration of 0.5% (wt%), the viscosity of STMP-CMHEC solution is 2.6 times higher than that of CMHEC solution. To be applied in fracturing fluids, STMP-CMHEC solution was further cross-linked with organic zirconium. The changes of viscosity and viscoelasticity modulus with time in the cross-linking process were studied. The effects of shear rate and temperature on the gelling process were investigated. The four-parameter cross-linking rheokinetics equation could describe the viscosity-time curves under different shear rates. [GRAPHICS]
