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。
补充资料：碳氧比能谱测井
将高能脉冲中子源 (14MeV)发出的快中子射入地层，与地层中元素的核发生非弹性散射，放出有一定特征能量的γ射线；测量油水中C、O,岩石中Si、Ca的γ射线含量，以探测油层和水层的油、水含量以及岩性的一种测井方法。在低矿化度、高孔隙度(≥20％)地层的套管井中，用本法可有效地确定区分油层、水层。
