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。 The Dongqiao Depression consists of three oil-bearing structures: Qiaokou, Baimiao and Duzhai. It is a deep natural gas-rich area with a large resource background. On the basis of constructing a fine interpretation and a new understanding of reservoir sedimentary facies, this paper dissects the deep reservoirs in the area of ​​Duqiao area, analyzes the hydrocarbon accumulation conditions and controlling factors and gradually clarifies the law of hydrocarbon accumulation. Duzhai area is a deep subsidence background with a simple structure and is a large-scale lithologic gas-bearing area. Condensate gas reservoirs under the control of developmental structure and lithology in Qiaokou area are lithologic reservoirs under the control of lithology and tectonism in the Baimiao area Central gas reservoir, reservoir formation conditions are complex.
