Situated in the northeast of China (42-49°N, 120-128°E),the Songliao Basin is aCretaceous nearshore continental basin which has been affected significantly by the adjacent marine transgression/regression.

CO_2 origin identification and its migration-accumulation research in eastern China rifted basins and offshore shelf basin;

Relationship between unconformity system and heterogeneous migration of petroleum in continental basins;

Application prospects of cross well seismic technique to continental basins;

Petroleum Geology and exploration prospects in the Cenezoic continental basins in the northern part of the Qinghai-Xizang Plateau;

Discussio on"one divides into four"property of system domain for stratigraphic sequence of terrestrial basins of China and its advantages;

In analysis of imaging stratigraphy for Cretaceous terrestrial basin in Xingjiang,in the light of modern stratigraphic theory,using analysis methods of sequence stratigraphy and tectonic sequence,the recognition marks of imaging sequence interfaces in remote sensing are built, and combined with 1∶50000 geological survey,the interpretating methods of imaging tectonic sequenc are discussed.

On the basis of analyzing the present situation of exploration in fault depressions in terrestrial basins,the conception of generalized sag is proposed,such as the alar part of the steep belt in fault depressions,the major sag,and the mid-lower part of slope belts.

Study on coal accumulation under marine transgression events in the epicontinental basin of North China;

The development characteristic of the sequence, the distribution pattern of strata, the basin evolution and filling , and the relationship between variations of base level and coal accumulation of epicontinental basin were expounded based on the base level cycles.

The sequence stratigraphic framework in the epicontinental basin and the terrestrial basin is established.
