It is showed that the propping fracture conductivity of gas log is 1.5 to 2.5 times higher than that of liquid log under the same testing conditions (such as haydite type, sanding concentration, temperature and pressure). A lower average sanding concentration in gas well fracturing should be adopted than that in oil well fracturing so as to obtain the same propping fracture conductivity.

结果显示，在相同实验条件下（陶粒类型、铺砂浓度、实验温度和压力），气测导流能力值比液测值高1.5~2.5倍，表明要获得相同的支撑裂缝导流能力，气井压裂中的铺砂浓度应比油藏低。
