| 摘 要： | 通过渗流试验和批量试验,对多孔介质水敏感性发生过程中颗粒释放的临界盐浓度进行了测定.试验结果表明:水动力条件也能导致颗粒释放的发生,但是释放量很小;当 NaCl 溶液浓度达到0.06mol/L 左右时,开始发生明显的颗粒释放现象,而其临界盐浓度并非是个单一值,可以确定为一个范围,即(0.06±0.005) mol/L;当NaCl溶液浓度为0.03mol/L时,颗粒释放量最大.

| Abstract: | With the seepage and batch experiments,this paper mensurated the critical salt concentration(CSC) which can result in particle release in the water sensitivity process for porous medium.The results indicated that:the water fluid power can result in particle release in part,but the quantity was very little;when the concentration of the NaCl solution reached about 0.06mol/L,there was a obvious particle release phenomenon,and the critical salt concentration(CSC) of the NaCl solution was not a simple value but ... |
