Abstract:

In low oil-abundance area to the south of Yellow river in Dongpu sag,oil and gas distributions are characterized by hydrocarbons to be accumulated in near-source limbs of structures, fault blocks controlling oil accumulation, oil/gas pools being small and scattered, and low level of trap fullness, due to poor quality of source rocks, complexity of structures and poor combination of reservoirs and seals. It is quite different from the high oil-abundance area in the north. Progressive exploration and development should be carried out in the low abundance area in the future, on the basis of careful interpretation of exploration targets, and taking fault block groups as appraisal objects and directional drilling as a measure.

Key words: Dongpu sag, oil-rich sag, low abundance area, reservoiring pattern
