Based on the compaction model of sandstone mudstone alternating beds, we advance a new formula for formation grain density, which conforms to grain volume and mass balance law.

又称催化剂真密度。表示炼油工艺流化床催化剂密度的一种方式。它是扣除了催化剂颗粒内微孔体积后的实体密度。

The log is made from resistivity, density, neutron, and sonic log data and shows porosity, secondary porosity, grain density, fluid analysis, water saturation, and formation analysis.

其资料来源于电阻率测井、密度测井、中子测井和声波测井。计算结果包括孔隙度、次生孔隙度、颗粒密度、流体分析、含水饱和度以及地层分析。
