【摘要】 东濮凹陷杜桥白地区主要包括桥口、白庙、杜寨3个含油气构造,是一个具有较大资源背景的深层天然气富集区。在构造精细解释、储层沉积相新认识的基础上,该文对杜桥白区深层油气藏进行解剖,分析了油气藏成藏条件与控制因素,逐步明确了油气成藏规律。杜寨地区为深洼陷背景,构造简单,是一个大型岩性含气区;桥口地区发育构造-岩性控制下的凝析气藏;白庙地区发育岩性-构造控制下的带油环气藏,成藏条件复杂。更多还原

【Abstract】 The three petroliferous structures, i.e., Qiaokou Baimiao and Duzhai in DuQiaoBai areas, Dongpu depression constitute an enrichment area of deep natural gas with a significant resources background. On the basis of detailed structural explanation and new insights into sedimeutary facies of reservoirs, the paper analyzes the deep oil/gas reservoirs in DuQiaoBai areas, in terms of formative conditions and constraints of oil/gas reservoirs, progressively the laws of oil/gas reservoirs are derived. Duzhai area with a deep sag background and simple structure is a large lithologic gasbearing zone; and structurallylithologically controlled gas condensate reservoirs are developed in Qiaokou area; and Baimiao area is characterized by the development of lithologicallystructurally controlled gas reservoirs with oil rings, whose reservoir formative conditions are rather complex.更多还原
