Logging data, as representations of lithology and physical properties of stratum, hold abundant information related to sedimentary cycles with high vertical resolution. The use of various methods to extract and analyze corresponding information will greatly promote the quantitative level in the study of stratum sequence. SP mirror (spontaneous potential), the ratio of sand and mud, CN (neutron)-GR (natural gamma ray) curve overlay technique and wavelet analyses were comprehensively analyzed in this paper. Application in X block of Algeria that it has a great effect and is a good tool in the parasequence sets study. Continuously improve the level of utilization of logging data, full logging data in sequence stratigraphic analysis of the role and scope of application will be beneficial for the development of sequence stratigraphy.
