Application of time—frequency analysis technique to recognition of fluvial facies sequence
Online published: 2013-10-08
The sedimentary facies of Upper Paleozoic Shihezi Formation in Sulige Gas Field are fluvial facies. Traditional stratigraphic division is generally using the principle of formation thickness, which always does not have isochronous. Under the guidance of high resolution sequence stratigraphy principle and Milankovitch cycle theory, based on core and logging data, this paper established isochronous stratigraphic framework of Shihezi Formation in Sulige Gas Field by using time-frequency analysis technique, and divided four middle-term cyclic sequences, nine short-term cyclic sequences and 22 super-short term cyclic sequences, which provides a new method for fluvial sequence division, has significant guideline for dividing sequence of fluvial reservoir, and further certifies the Milankovitch cycle theory.
