摘要
在放射性测井作业中,时间常数τ和测量速度V是决定原始资料质量的基本测量技术条件。必须根据放射性测井的误差特点和统计起伏记录“涨落误差”,在规定的测量精度下确定选择τ值和测井速度的基本原则。由于τV值对测井曲线有一定影响,所以应按校正公式校正“深度偏移”。
Dong Desong. Selection of Time Constant and Logging Speed for Radioative Logging. WLT, 1993, 17 (5): 344~348 In radioactive logging quality of raw data depends upon the selection of time constatnt τ and logging speed V which are the basic measuring conditons. Statistical error should be recorded according to error characteristics of radioactive logging and statistical fluctuations. And the basic principles for the selection of time constant τ and logging speed should be determined in accordance with the specified measuring accuracy. Depth error should be corrected with correction formula due to the effect of τV values on logs.
