补偿密度测井仪的刻度与密度计算

DENSITY CALCULATION AND CALIBRATION OF COMPENSATED DENSITY TOOL

    摘要
  • 摘要: 在分析XAM/XAP补偿密度测井仪刻度资料和密度计算方法的基础上,指出了原刻度资料和密度计算方法的一些缺陷;对XAM/XAP补偿密度测井仪重新进行了刻度,并制作了新的脊肋图;依据脊肋图研究出肋线方程系数和高次多项式两种新的补偿密度计算方法,从而使密度测井的精度提高到0.03g/cm3。

     

    Abstract: the article point out some few shortcoming of calibration and compensation algorithm base on analysis calibration information of XAM/XAP compensated density tool and compensation algorithm The XAM/XAP was calibrated again and then the new ridge-rib graph was made.Two new approaches for density compensation including the rib line equation coefficient and the high-order polynomials were worked by use of the information of new ridge-rib graph.So that the accuracy of density log canimprove to 0.03g/cm3.
