Abstract:

When high-resolution sequence stratigraphy represented by T. A. Cross Genetic Stratigraphy Group of Colorado School of Mines was introduced to the pubic,it immediately drew the attention of academic circles.The practical effect in application is remarkable.This marks a new development in sequence stratigraphy.The high-resolution sequence stratigraphy introduced in this paper focuses on more accurate prediction of sedimentary mineral deposit,especially concrete objective of oil and gas exploration.The high-resolution sequence stratigraphy takes the stratigraphic and sedimentary process-response dynamic principles,including the principles of stratigraphic base level,volumetric partition,factes differentiation and rule for chronostratigraphic cycle correlation as its theoretical bases.The practice of hydrocarbon exploration and development has proved that the high-resolution sequence stratigraphy has significant importance in factes analysis,3-D prediction of reservoir and the establishment of petrophysical model for fluid-flow numerical simulation.
