In the past few years,great achievements have been made in the exploration in the buried hill reservoir of Chengdao.Structure and reservoir conditions control the accumulation and enrichness of oil and gas in the buried hill.This paper studies the structural evolution,the controlling factors on reservoir and its distribution and demonstrates the role of structural evolution of buried hill on the distribution of strata and reservoirs.Results indicate that the Chengdao buried hill experienced long time weathering denudation and multiple complex evolution.Reservoir space has great diversity and the weathering crust reservoir is the dominant reservoir in the buried hill.As the depth to the weathering front increases,the development of the reservoir decreases and inner buried hill reservoirs increases which is controlled by interior fault.This paper can provide some references to the exploration of the buried hill in Chengdao region as well as the Bohai Sea Bay basin.
