根据测井响应特征的差异，将其划分为中、高孔渗高含气丰度气层和中、低孔渗低含气丰度气层及泥质粉（细）砂岩气层三种类型。
The gas reservoirs may be classified three types of high abundance gas-bearing formations with middle-high porosity-permeability , low abundance gas-bearing formations with middle-low porosity-permeability and gas-bearing argillaceous siltstone formations according to the difference of log response characteristics .
