东濮凹陷西部斜坡带油气勘探潜力分析

Analysis of Hydrocarbon Exploration Potential in the West Slope Zone of Dongpu Depression

通过对东濮凹陷西部胡庆地区石油地质特征的综合分析 ,结合该区已发现油藏的特征和类型 ,探讨了石家集、长垣断裂对油气聚集的控制作用 ,提出在胡庆地区一台阶应用油气环洼富集分布理论 ,实现环洼勘探 ;以复杂断块群油气勘探理论指导二台阶深层和石家集、长垣断裂带内部小断块群的精细勘探 ;探索潜山新类型油气成藏规律 。

Through a comprehensive analysis of petroleum geologic properties in Huqing area in the west of Dongpu Depression, the controlling effect of faults in Shijiaji and Changyuan areas on hydrocarbon accumulation is discussed in combination with the reservoir properties and types which has been discovered in the area. It is proposed that a circular depression hydrocarbon enrichment theory is used to conduct a circular depression exploration on the first step in Huqing area, the theory of hydrocarbon exploration in complicated fault block group is used to guide the precision exploration of deep formation on the second step and small fault block group in Shijiaji and Changyuan fault zones and as well as to search for the new types of reservoir forming laws of buried hills for cultivating new fields for looking for oil.
