It will be more reasonable to use the result of gas log conductivity testing as the guideline for evaluation of potential before fracturing, optimization of fracturing design, forecast of effects and selection of proppants. The method of gas log conductivity should be used for laboratory research on fracturing of gas reservoirs.

用气测导流能力的实验结果来指导气井的压前潜力评估、压裂优化设计、压后效果预测和支撑剂的优选评价将更具合理性和针对性，气藏压裂的支撑裂缝导流能力实验最好采用气测方法。

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。

Water lock effect is one of the main factors affecting gas well productivity, especially in low permeability gas reservoirs.

水锁效应是影响气井生产的一个主要因素，尤其是在低渗透气藏这种影响作用更显著。

The pump and pump system (10) of the present invention is designed to remove liquids, gas, sand, and coal fines from gas and/or oil well bores from close to the rock face.

本发明的泵和泵系统(10)用来取出气井和/或油井中接近岩石表面的液体、气体、砂和煤粉。
