【 摘 要 】

The ability of logging curves to reflect the rock interface is related to logging principles, which is often different from the layer interface determined by coring. According to basic principle of logging curve, analyze the corresponding relationship between comprehensive lithologic boundary determined by coring and the boundary determined by well logging curve. The identification method combining the two technique is given. In view of that the logging curves are insensitive to some thin layers and transition lithology, the reasonable value method are given as a result. Using this result can well judge the change trend of lithologic profile.
