其中以自然伽马测井确定湿灰分,该方法的前提条件是湿分主要是泥质且泥质不具放射性元素;以密度测井与人工伽马测井确定含碳量,并对密度测井作湿分校正;以灰分校正后的密度测井确定饱和水孔隙度;含气量的估算以声波测井和密度测井组成的复合参数ΔT/dDEN来确定,或以视电阻率曲线确定含气量。

Cuttings may also be deposited in the bottom of the horizontal hole because of gravity of the earth,and it will have lower density value than the formation, so cuttings beds can have a significant effect on the density log responses.

在水平井中,由于重力作用井筒底部会聚积一定厚度的岩屑,而岩屑层的密度小于地层的密度,所以岩屑层对密度测井响应有一定程度的影响。
