Abstract:

自主研制了一种岩心表面吸附层耐冲刷的实验装置,成功测试了岩心表面纳米颗粒吸附层的耐水流冲刷能力。实验结果显示了纳米吸附层表面润湿性由强亲水转变为疏水、再转向亲水的过程。同时表明,该装置具有连续不间断流动、一次性测试10块岩心片样品、流量可调、不停泵更换样品和水位恒定自控等特征,达到了实验要求。
A device for anti-scouring experiment of the core surface is developed, and the water resistance of the nano particle adsorption layer on the core surface is successfully tested. The results show that the surface wettability of the nano adsorption layer is changed from hydrophilic to hydrophobic, and then to hydrophilic. The device has some features of continuous flow, testing 10 core samples at a time, convenient adjustable flow rate, taking out samples without stopping the pump and au-to-control constant water level, which have met the experimental requirements.
