水基压裂液的制备与性能优化
Preparation and performance optimization of water-based fracturing fluid
Three kinds of hydraulic fracturing fluid,respectively based on guar gum,sesbania gum and sodium carboxymethyl cellulose as thickener,are developed.Their performances are investigated from perspectives of apparent viscosity,picking and hanging performances,gel-breaking performance,temperature resistance,sand-suspending performance and residue content.It is found that the water-based fracturing fluid with guar gum as thickener exhibits the best among the three kinds,its apparent viscosity is 37.5 mPa·s,which drops to less than 50 mPa·s at 60℃.It can realize good picking and hanging performances,and its gel-breaking is completed after 10 h.Its sand-suspending performance is 6 mm/min,and the residue content is 376 mg/L.All indexes of this guar gum-based fracturing liquid meet the requirements of SY/T 6376—2008 “General Technical Conditions for Fracturing Fluid” evaluation standard,showcasing an excellent comprehensive performance.This fracturing fluid system provides a certain reference for the expansion and optimization of conventional fracturing fluid system and the fracturing-permeability enhancement technology in viscous soil.
