东营凹陷纯化潜山构造特征与勘探目标选择

结合钻井和地震资料研究纯化潜山的构造特征，精细描述了纯化潜山的构造演化过程，在此基础上探讨了纯化潜山的烃源岩、储集层、盖层以及圈闭等油气成藏条件，研究表明，纯化潜山属于典型的块断山，其形成演化与石村断层的发育及潜山北部利津洼陷的强烈下陷有着密切关系。纯化潜山储、盖条件以及圈闭条件都较好，油气成藏的主控因素是烃源岩以及油气运移通道，纯化潜山南部沿石村断层上盘一线为较有利的勘探目标区。

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.
