High resolution sequence stratigraphy of Yanchang Formation in Fuxian area, Ordos Basin
Online published: 2012-12-20
Under the guidance of high resolution sequence stratigraphy theory, based on field crop, cores and well logging data, the Yanchang Formation in Fuxian area can be divided into one super long-term sequence cycle（SLSC）, four long-term sequence cycles（LSC）, 22 middle-term sequence cycles（MSC） and several short-term sequence cycles （SSC）. The short-term sequence cycles can be subdivided into two species and seven subspecies. We analyzed the styles, sedimentary facies and spatial distribution of the different short-term sequence cycles. We chose middle-term sequence interfaces and max flooding surfaces as correlation interfaces in stratigraphic correlation, and established the sequence stratigraphic framework of Yanchang Formation in Fuxian area, which can provide a theoretical basis for
recognizing the distribution of sand bodies and source rocks.
