测井资料作为连接地震与地质的桥梁和纽带,在地震资料构造解释、反演以及储层预测中得到了广泛应用。通过理论及实际测井数据分析,探讨了测井数据的频散特性、不同仪器测量结果的差异性等,指出了地震资料解释中应用测井数据应该注意的几个问题:①地震数据与声波测井数据之间存在由速度频散引起的差异,层位标定中应进行必要的匹配校正,地震反演中不能过分追求反演结果与测井数据的一致性;②测井数据并非真值,同样存在一定的误差,应用中不可将测井数据绝对化;③基于测井数据的统计回归分析应注意数据选取的系统性、数据分布的均匀性以及数据量的充分性。
Logging data, as a bridge and link connecting seismicity and geology, has been widely used in seismic data interpretation, inversion and reservoir prediction. Through the analysis of theoretical and actual well logging data, the dispersion characteristics of well logging data and the differences of measurement results of different instruments are discussed. Some problems that should be paid attention to when using well logging data in seismic data interpretation are pointed out: ① Seismic data and sound waves There are differences caused by velocity dispersion between the well logging data, and the necessary matching correction should be carried out in the calibration of the horizon. The consistency between the inversion result and the logging data can not be excessively pursued in the seismic inversion. ② The logging data is not true , There is also some error, the application of logging data can not be absolute; ③ Logistic regression analysis based on statistical data should pay attention to the systematic selection of data, the uniformity of data distribution and the adequacy of the amount of data.
