体积流过量试验结果显示,当注入150倍孔隙体积注入水时,因粘土膨胀,渗透率下降达28%。
The result from the testing by volume flow overrate demonstrates that when injected water as much as 150 fold of pore volume is used, permeability is reduced as much as 28% due to clay swelling.
水力压裂过程中存在的损害主要包括粘土膨胀与颗粒运移损害、机械杂质引起堵塞损害、支撑裂缝导流能力的损害等。
The damage during hydraulic fracturing mainly included clay swelling and grain migration, built up created by mechanical impurities, the damage of fracture conductivity and so on.
