摘要
Abstract
Low molecular weight guar gum fracturing fluids play an important role in the enhancement of oil-gas recovery for low permeable oil-gas reservoirs. The production of the regenerable cross-linked gel systems consisting of low molecular weight carboxymethyl guar gum (LMWCMG) and borax were studied. The effects of LMWCMG concentration and borate concentration on the formation and regeneration of the gel systems were investigated, and the stable can be regenerated LMWCMG cross-linked gel systems were obtained. Furthermore, the Theological properties of the gel systems with different regeneration times were studied. The results show that the regenerable gel systems possess good visco-elasticity and thixotropy, and shear thinning properties. Non-linear co-rotational Jeffreys model can be applied to describe the viscosity curves of the regenerable LMWCMG gel systems correctly, and using the model, the calculated values are in good agreement with the experimental data.关键词
