In order to improve accuracy and precision of automatic correlation of sequence cycles, to solve problems of difficult division, artificial conditions and multiplicity of high resolution sequence cycles, based on previous research and actual well logging data, this paper takes the different characteristics of various sedimentary sequence cycles in Chinese continental extensional basins as the objective, and conducts the research of wavelet frequency analysis. This paper clarifies the basic theory that wavelet frequency analysis is used to divide various sedimentary sequence cycles, and sets up the quantitative standards and response standard model for different types of sedimentary sequence cycles. We can realize the goal of applying wavelet frequency analysis in sequence boundary recognization, sequence unit division, high-resolution division and isochronous correlation of complicated reservoirs, and provide a powerful tool for division and isochronous correlation of sedimentary sequence cycles.
