Based on new theories and methods of petroleum system and organicgeochemistry, the author studied and discussed hydrocarbon-source rock of lowerTertiary in Yucheng area in several aspects, such as sedimentary organic facies,abundant of organic matter, organic type, maturity, reservoir property, andclassification of oil-gas system and their characteristics.

Characteristics of volcanic rock reservoirs in Ou-Huang area of the eastern sag in Liaohe depression and prediction of favorable reservoirs;

Sequence stratigraphic characteristics and petroleum distribution in the Palaeogene of northern section in the eastern sag of Liaohe Basin;

On the Relations between Structural Evolution and Oil and Gas Accumulation in the Eastern Sag of Liaohe Depression;

Fluid inclusion microthermometry and apatite fission track analysis were used to reconstruct the Tertiary paleotemperature of the East depression,Liaohe basin.

Taking the unconformity of Es_(1+2)/Es_3 in the northern region of east depression of Liaohe Basin as a case, the relation of unconformity with hydrocarbon migration and accumulation was studied.

The Shahejie Formation of the Paleogene in the deep zone of the middle area of the East Depression in Liaohe Basin is made up of its Member 1 and Member 3 and lacks its Member 2 and Member 4.

The generating hydrocarbon intensity cneter is Niuju Qinglongtai depression,showing the there were generating hydrocarbon center in northern section of the East Sag that is the basis of petroleum systems.

The study of major faulting in the middle sector of the eastern depression of the Liaohe basin indicates that this region underwent pre-Cenozoic and Cenozoic evolutionary stages.
