A MODEL FOR FORMATION OF OIL POOLS IN THE ZHAOXIAN ANTICLINE OF THE CENTRAL HEBEI DEPRESSION

The Zhaoxian anticline is a new oil-bearing structure discovered in 1998, with 1300×10⁴t of oil reserve. The total area of the anticline is 70km² and trap area 55.2km². During the progressive exploration and development, the anticline was studied in detail and the control factors on formatim and distribution of oil pools were clearly definited in accordance with reservior description. Three kinds of oil pools were classified, including structural, lithological-structural and structural-lithological oil pools. The study may provide some valuable suggestions for future exploration and development of the anticline.
