摘要
通过岩心实验对纳米颗粒的作用进行评价分析,对比应用纳米颗粒和未应用纳米颗粒情况下的CO2波及范围、孔隙压力等参数。结果显示:纳米颗粒可以有效提高CO2的波及范围,减弱指进现象,同时提高压裂过程中的孔隙压力,对于页岩气藏压裂具有实际指导意义。
Analyze the effect of nanometer particles by the core experiment, comparing the parameters of the range of carbon dioxide and the pore pressure in the case of with and without the use of Nano particles. The results show that the Nano particles can effectively improve the range of carbon dioxide, reduce the finger into the phenomenon, and improve the pore pressure in the process of fracturing. It can offer the practice guidance for shale gas reservoir fracturing.
