A Study And Application Of Super Guar Gum Fracturing Fluid Technology

process-enhanced guar is one of the natural Guar gum thickening agent,which is produced by the most advanced delicate workmanship production. The viscosity measurement of process-enhanced guar and hydroxy-propyl guar solution indicate that the molecular weight of process-enhanced guar is nearly 1.37 times greater than the molecular weight of guar, and it is nearly 1.62 times greater than the molecular weight of hydroxy-propyl guar. The process-enhanced guar is much more simpler than hydroxypropylguar gum in preparing fracturing fluid, better water solubility, no swelling, strong operability, To achieve preparing liquid quickly, Meet the requirement to fracturing.This analysis and study the performance of process-enhanced guar, characterizing of the polymer structure, measuring the molecular weight, And characterizing network topology of super Guar gum instant, analyzing the character of fast hydrating,character theory of low fracturing fluid residue and the amount to be used, clarifying the feature of molecular structure and the impacting to property of fracturing.Research shows that the use of concentration grew thicker 50% reduction on average than hydroxypropylguar gum, fracturing fluid residue level 45% reduction,fracturing sap system lighten up to the floor and cracks in the ability to the extent of damage flow conductivity ;process-enhanced guar fracturing liquid has a cold and heat resistance to make a cut, with the ability to apply to 30~100°C low permeate oil and gas accumulation fracturing production of reform.
