LABORATORY PERFORMANCE EVALUATION OF CHEMICAL SAND STABILIZING AGENTS FOR UNCONSOLIDATED SANDSTONE RESERVOIR
A functional polymer based sand stabilization system was evaluated,and the mechanism of sand stabilization of this polymer was also analyzed.The static evaluation results indicate that the vis-cosity of the functional polymer is low,and 0.2％polymer viscosity is 15.8 mPa·s,Compared with the blank group,the median particle size of quartz sand treated with 0.1％sand stabilization fluid rea-ches 131.8 μm,an increase of three times.The dynamic evaluation experimental results show that af-ter treating quartz sand with 0.1％sand stabilization fluid,the critical sand flow rate is increased to 8 mL/min.At the same time,when the water injection rate reaches 20 mL/min,the sand production rate of the sand filling tube is 0.027％,and the sand stabilization effect is good.
