目的：探讨濮城构造沙三、四段油气成藏条件及勘探潜力。方法：对东濮凹陷股城构造沙三、四段地层特征、构造特征及沉积特征进行分析。结果：论述了该区深层油气藏形成条件及油气分布规律。结论：本区主要发育低渗透层状断块油气藏、构造一岩性油气藏和岩性油气藏，并指出了下步勘探的主要方向和目标。
Objective: To investigate hydrocarbon accumulation conditions and exploration potential of the third and fourth member of Pucheng Formation. Methods: The stratigraphic features, structural features and sedimentary characteristics of the third and fourth member of Shahejie Formation in Dongcheng Depression were analyzed. Results: The formation conditions of deep reservoirs and distribution rules of oil and gas in this area are discussed. CONCLUSIONS: Low-permeability bedded fault block reservoirs are mainly developed in this area, and a lithologic reservoir and lithologic reservoir are constructed. The main directions and targets of next exploration are pointed out.
