Structural characteristics of Chunhua buried hill in Dongying Sag and exploration target selection

This paper studies structural characteristics of Chunhua buried hill combining with drilling and seismic data, and describes structural evolution process of Chhunhua Buried hill in detail. Then it discusses reservoir forming conditions including source rock, reservoir, seal and traps of this area. Study result shows that Chunhua buried hill is typical fault block hills. Its formation and evolution are closely related to development of Shicun Fault and strong subside of Lijin Sag to the north of the buried hill. Chunhua buried hill has favorable conditions of reservoir and seal. Main controlling factors of reservoir forming are hydrocarbon source rock and hydrocarbon migration channel. Area along hanging wall of Shicun fault in south Chunhua buried hill is favorable exploration target area.
