The article first analyzes the main characteristics, procedure and latest mode of foreign oil pool management & administration, then introduces the status of oil pool management & administration in domestic oilfield enterprises as well as the gap between China and foreign countries.

This paper has mainly discussed the similarities and differences between oil pools and gas pools in the respects of hydrocarbon sources,reservoir properties,migration and accumulation mechanisms,and preserving conditions.

In recent years,a large-scale ultra -low permeability lithologic and stratigraphic oil pool was found in Segment 4+5～9 of Yanchang Formation.
