Study the Erosion Thickness Restoration of Qianjiang Formation in Qianjiang Depression;

Many methods can be used to restore formation denudation thickness, such as stratigraphic correlation, deposition velocity, well log, compaction curve, vitrinite reflectance, sporopollen and wave analysis method, etc.

It is an important basis for reconstructing the strata denudation thickness in basin quantitative study.

Strata antithesis method uses two dimension seismic data to comeback the plane distribution character of Xishanyao Formation,and sedimentary ratio analysis method uses well geological layer and precise chronology framework data to comeback well denudation thickness.

Restoration of eroded strata thickness in Cretaceous/Jurassic unconformity in hinterland of Junggar Basin;

On the basis of the scientific definition of eroded thickness and the analysis of factors that affect eroded strata thickness, a new category scheme on eroded strata thickness restoration in sedimentary basins is propose.

This is the first time to obtain the eroded strata thickness of the fourth member of the Shahejie Formation in Huimin Depression,Bohai Bay Basin system atically by means of vitrinite reflectance.

Restoration of erosion thickness in Xuanhan-Daxian area,northeastern Sichuan basin;

The cause of "shallow maturation" of source rock in Jinhu depression is analyzed with data of source rock maturity index and palaeotemperature test on the basis of reconstruction of erosion thickness of Sanduo formation and analysis of thermal evolution history.

Using seismic, logging, and assaying data, and combined with vitrinite reflectance erosion thickness restoration method and seismic stratigraphy Paleogeomorphology restoration way, we have restored Caledonian paleogeomorphology in the central area of Tarim.

According to this method,the eroded thickness of strata of Turpan and Hami basin can be obtained as follows:the Triassic is less than 500m in the southern area of basin;the Jurassic is between 600m and no erosion in Taibei depression in the northern area of basin;and is from 800m to 1800m in the foreland mountains of Taibei depression.
