摘　　要：以西部凹陷古潜山油气成藏条件为重点 ,针对上覆分布不均 ( 0～ 1 1 0 0m)的玄武岩地震资料品质差 ,识别古潜山圈闭难度大 ,裂缝性储层岩性复杂 ,裂缝发育程度不确定因素多等复杂地质情况 ,加强基础研究及规律性认识。通过对辽河坳陷西部凹陷古潜山油气成藏条件的分析认为 :该区石油地质条件有利于古潜山油气藏的形成 ,在上覆沙河街组勘探程度较高的情况下 。This paper studies the forming conditions of buried hill reservoirs in Liaohe western sag. In accordance with the poor quality of seismic data of the unevenly distributed overburden basalt (0～1 100 m), the difficulty of buried hill trap recognizing, the complex lithology of fractured reservoir, and the uncertainty of fracture development, we have enhanced the basic and regularity study. Analysis shows that, the geological conditions of this area were favorable to forming of buried hill reservoirs. Under the condition that overlying Shahejie formation had a high degree of exploration, the underlying buried hill reservoir still is a favorable exploration direction in next step.
