实验研究了注水井增注用的4种商品表面亲油改性纳米二氧化硅改变岩石表面润湿性的能力。
The ability to alternate rock wettability is studied for 4 commercial surface modified lipophilic nanometric silica (LNS) used for stimulating water injection Wells.
该防砂剂吸附于岩石表面使得岩石表面的润湿性向亲水方向变化，导致岩心的油相渗透率增加和水相渗透率减小，说明该防砂剂不但具有防砂作用还具有堵水功能。
The pictures of core scanning by electron microscope indicate that there are good porosity and connectivity in the consolidated core. This sand control agent adheres to rock surf…
