Relation between infilling patterns of short-term base-level cycle and macroscopic reservoir heterogeneity-taking Chang6 to Chang7 turbidite fan of Yanchang Formation in Longdong area as an example;

Study on relation between sequence of short-term base-level cycle and reservoir property change model of Triassic Chang 6~8 oil reservoirs in Eastern Gansu, China;

Sequence analysis and isochronous correlation of the short-term base-level cycles in the third oil reservoirs of the Yanchang Formation in the Huachi Oil Field,Ordos Basin;

The huge thick mudstone section deposited at the transfering position from uprising to subsiding of the long-term stratigraphic base-level circles or at the upper part of (nonsymmetric) long-term stratigraphic base-level.

Using the data of drill hole 86-46 in Dashiqiao, Hulin City, the high-resolution sequence stratigraphic division of the Hulin Formation in the Dunmi downfaulted basin, eastern Heilongjiang, was made, and three medium-term datum plane cycles were recognized.
