A fine geological model is presented based on a high-precision reservoir framework model, and the new technologies including high-resolution sequence stratigraphy, reservoir quantitative simulation technology and the foundation of fine reservoir geological database will be able to provide an important support for improving precision of framework model of sandstones.

In order to study acoustic wave propagation along cased calibration boreholes in which simulated formations are finite and the first and second interfaces are both well bonded, full waveforms along borehole axis generated by a point\|like acoustic source at different offsets and frequencies are calculated with real axis integral method.

Three dimensional quantitative simulations on the formation and evolution of aeolian sand ripples and sand dunes are presented.

Quantitative Stratigraphy of upper Cretaceous in Tethyan-Himalaya;

This paper reviews the development of quantitative stratigraphy, discusses some properties of its object (stratigraphic time-series), explains its major objectives.
