The transmission efficiencies of combination logging data and imaging logging data are restricted under finite bandwidth.A lossless data compression method based on the characteristics of logging data is put forward,it can transfer the logging data to surface after they are compressed,and therefore the transmission efficiency of logging data is effectively improved.The compression plan,compression processing and algorithm are described.Different types of data are compressed using different compression methods,and the compression ratios of them are compared.It is shown that,the compression ratio of frame-related compression method is the greatest,and the compression ratios of other compression methods are smaller;the compression ratio of the first kind of data is greater,that of combination logging data is secondary,and that of imaging logging data is the least;the compression ratio slightly increases with the increase of the quantity of the data.
