Diagenesis in sequence stratigraphic framework of Paleogene strata in Bozhong Depression;

Petroleum Generation History of Lower Tertiary Source Rocks from the Bozhong Depression of the Bohaiwan Basin;

Moho behavior and basin formation mechanism in Bozhong depression;

A study on Paleogene tectonic sequences in Bozhong sag;

Natural gas in the Bozhong sag is of organic origin.

In Bozhong Sag, the biodegraded oil is characterized by high density, high viscosity, lower wax content and lower ratio of saturate to aromatics(<3.

Photoelastic modeling of the tectonic stress field in the central part of the Bozhong depression;

Distributional Characteristics of Active Source Rocks in Bozhong Depression and Its Control to the Hydrocarbon Accumulation in Oilfield;

Geochemical Character of the hydrocarbon in BZ26-2 Oilfield,Bozhong Depression and its implication for petroleum accumulation;

Aresearch of prediction and description techniques for fluvial reservoir in Bozhong 34 area ,Bohai sea;

Based on a vast amount of data from thin section,X ray diffraction,SEM and mercury penetration analysis,reservoir diagenesis and porosity evolution are studied for Tertiary Guantao Shahejie Formation sandstones in Bozhong area,recognizing some diagenetic stages and resulting in a primary diagenetic model.
