摘要
在补偿密度测井的基本方程式的基础上 ,详尽地推导了视密度和密度校正值与长、短源距计数率的线性方程式、计算脊、肋角的关系式 ,分析了三点刻度的局限性 ,解释了四点刻度的原因。最后 ,介绍了四点刻度时 。
On the basis of basic equation of compensated densilog,the linear equation of apparent density and density correction from long and short spacing count rate is derived in detail .The limitation expression of spine and rib angles is given by calculating.The relatation of three point calibration is analysed,and the reason for four point calibration is explained.Finally,the output relational expression of density value and correction in four point calibrating is also analysed.
