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.
