【摘要】 在 VSP测量过程中 ,生产单位要进行 2次测量 :一次是生产测量 ,一次是检验测量。通过 2次测量的初至时差来检验 VSP观测数据的准确性。利用 x2 检验法和偏度、峰度检验法对 85口井的 VSP数据进行统计分析 ,证明了 VSP重复观测时差分布呈正态分布 ,同时指出 VSP重复观测时差与深度也无明显关系更多还原

【Abstract】 In the process of VSP measurement, two measurements are made,one is for producing the other is for checking The accuracy of VSP observed data is inspected by using the first arrival moveout of the measurements VSP data are statistically analyzed on 85 wells by using the methods of x 2 inspection,skewness and kurtosis inspection, normal distribution of the first arrival from VSP repeated observation is proved,at the same time it is pointed out that the first arrival of VSP repeat obseration is not obviously related with depth更多还原
