Analysis of the mess in sequence hierarchy applied in the industrialized application of the sequence stratigraphy
Online published: 2007-03-15
The mess and absence of unified criterion of sequence hierarchy have constrained the industrialized application and its assurance and effect. The origin of the present confusion mainly contributes to the different analysis about the control on sequence pattern which lead to them issue of both nomenclature cyclist and stage. Based on the practical effect and feasibility and consideration of both cyclist and stage, a suite of terminology system is presented. Firstly 3rd sequence is considered as the base which can be grouped into 2nd or 1st order sequence or subdivided in to 4th, 5th even 6th sequence based on the suite of criterion. The only criterion of the division of 3rd sequence is the unconformity, which also implies the absence of the unconformity in such sequence. Owning to such base, the system tracts can be discriminated and divided according to the first flooding surface and the maximum flooding surface. So called 4th sequence is a system tract practically with no cyclist. Based on the reconcilability of seismic data, the 3rd sequence can be subdivided in to A and B type. Such three hierarchies could correspond to the basin analysis & resource evaluation, play evaluation and objective prediction, reservoir characterization and progressive exploration and development respectively. Among the above mentioned terminology, the 4th sequence plays the key role in sedimentary mapping and the prediction of the promising area of the subtle traps.
