Abstract: This paper presents six types of stratigraphic oil pools in Jiyang depression and the conditions of their formation.These oil pools are related to the five unconformity surfaces of cenozic era.It lays particular stress to the point that they lie mostly above and below the unconformity surfaces in proximity to the source beds.Because the depression is like a dust pan,both its steep and gentle slopes as well as the low uplifts in the basin are favourable sites for the formation of stratigraphic oil pools,particularly in the lithofacies zone of inverted cyclothem.Which should be given priority in exploration.
