A study on the structural evolution and the petroleum characteristics of Gudao carbonate buried hill in Jiyang depression,China;

Research and application of multiplex acid fracturing technique in buried hill reservoir in Hekou;

Hydrocarbon accumulating model and forecasting of favorable prospecting areas in buried hill of Budate Group,Beier Sag;

Evaluation of fracture scale of buried-hill reservoirs with the associated dimension of sonic logs;

Genetic classification and distribution of Ordovician carbonate buried-hills in Huanghua depressionBohai Bay basin;

The Reservoir Study on Proterozonic Buried-hill in Damintun Sag, Liaohe Basin;

The favorable oil-gas traps are located at around oil-generation sags,draping anticlines of buried hills,some structural lithofacies zones and compound hydrocarbon accumulation zones.

,the structure characteristic is studied and the evolving process of buried hills is reversed ,the results show that there exist three kinds buried hills: the early formed palaeogeomorphology ,the medium-term formed distortion and temporaneous buried hills controlled by temporaneous faults .

Transversal prediction for reservoir parameters of fractured reservoirs in buried hills;

Characteristics and distribution mode of buried hill reservoirs in Futai oilfield;

Analysis of reservoir forming conditions in Binnan - Lijin buried hill;

Inner buried hill laminar formation or lithology association together with minor faults form inner buried hill traps.

The exploration work for buried hill reservoir has changed from much distinct hill,such as top buried hill,middle part buried hill to much deeper,blinder,complex buried hill,such as,lowly buried hill,inner buried hill.

Exploration targets have shifted from the Shallow-medium buried hill reservoirs with clearer reservoir forming conditions to the low and inner buried hill reservoirs with deeper,hidden and more complex features.
