欢喜岭油田兴隆台油层分布特征及成藏规律

摘要

The Els1+2 members of the Xinglongtai reservoir in the Huanxiling oilfield is characterized by extensive oil - bearing area, drastic net pay variation and uneven degree of reserves producing. Fine geological study has been carried out for this reservoir through stratigraphic correlation and division, structural interpretation and sedimentary facies study. This paper presents oil and gas distribution and reservoir forming pattern, and scrutinizes the key factors of hydrocarbon accumulation and their spatial disposition, as well as reservoir forming time and model. This study can guide in - depth regional geologic research for finding potential targets.%欢喜岭油田s1+2段兴隆台油层含油分布范围广,厚度变化大,储量动用程度不均衡.文章从基础地质资料入手,运用地层对比与划分、构造精细解释、沉积相研究等技术,对欢喜岭油田兴隆台油层进行精细地质研究,重点描述了兴隆台油层的油气分布特征及油气藏类型,深入分析了油气成藏要素及空间配置、成藏时间及成藏模式等成藏规律,对深化区域地质研究和寻找有利目标区具有指导意义.
