Overview of research into formation mechanism and distribution law of stratigraphic reservoir

The sequence boundaries controlled distribution of stratigraphic reservoir.

Its trait of basin evolution and space-time distribution of hydrocarbon source rock,tectonic development characteristics and oil-gas migration-accumulation modes decide the fact that the main type of the large oilfields is the stratigraphic oil-gas reservoir and that of the anticline oil-gas reservoir is secondary,which determines the development and space-time distribution of the la.

To meet the demand for exploration of the lithologic and stratigraphic oil and gas reservoirs, the oil field has developed four items of dominant technologies-high-precision 3-D seismic data acquisition and processing technology, systematic deep-well and slim-hole drilling technology and.

Huabei Oil Field has adopted a series of new approaches for organization and management of the exploration projects in the light of the characteristics of lithologic and stratigraphic oil and gas reservoirs.

Lithologic and stratigraphic oil and gas reservoirs have some difficult technological issues, such as difficult identification of trap and difficult prediction of the formation conditions for the oil and gas reservoirs.

Causative factors and countermeasures of the exploration failure of stratigraphic onlap hydrocarbon reservoirs-taking Taiping and Chenjiazhuang Oilfield as examples;
