1·The flow conductivity of propping agent in hydraulic fracture is affected by many kinds of factors.

水力裂缝中支撑剂的导流能力受多种因素的影响。

2·The device that is attached to the blowout preventers during a frac job. Fluid and propping agent are pumped under pressure into the frac head and down the well.

在压裂作业期间装在防喷器上的装置。压裂液和支撑剂在压力下被泵入压裂头，并沿井向下流动。

3·Experimental study shows that the damage rate of fracturing fluid to fracture surface is between 31. 84% and 36. 28%; the damage rate to propping agent layer is between 29. 27% and 30. 04%.

针对太2气层的实验研究表明，压裂液对裂缝壁面的伤害率平均在31.84% - 36.28%之间，压裂液对支撑剂层的伤害率平均在29.27%—30.04%之间。
