安丰全,唐炼,牛华,等.补偿密度测井高分辨率处理技术研究.测井技术,1997,21(5):323~326从密度测井原理入手,对补偿密度测井曲线纵向分辨率低的原因进行分析,发现补偿密度测井数学转换模型是导致其分辨率低的重要原因之一。提出对α因子技术的改进方法,即加入井眼影响校正因子和相关性因子,使近接收器高频信息真实可靠。该处理方法不仅可将补偿密度测井曲线的纵向分辨率提高到0.20m,其统计精度优于常规高密采样密度曲线,而且保持了常规采样密度测井曲线的统计精度。
An abundance of all, Tang Lian, Niu Hua, and so on. Study on High Resolution Processing Technique of Compensation Density Logging. Logging Technology, 1997,21 (5): 323 ~ 326 Based on the principle of density logging, the reasons of low vertical resolution of compensation density logging curve are analyzed. It is found that the mathematical model of compensation density logging results in low resolution One of the important reasons. The improved method of α-factor technology is proposed, that is, adding wellbore affects the correction factor and correlation factor so that the near-receiver high-frequency information is real and reliable. This method not only improves the vertical resolution of compensated density log to 0.20 m, but also improves the statistical accuracy over the conventional high density sampling density curve and maintains the statistical accuracy of the conventional sampling density log.
