| 摘 要： | 泌阳凹陷北部斜坡复杂断块群油田以断鼻、断块及断层+岩性油气藏为主,垂向含油层系多,平面上叠合连片,油气主要富集在鼻状构造主体部位的断鼻断块内。通过对研究区油气控制因素的分析,指出继承性的鼻状构造控制了油气聚集方向和富集程度,油气藏含油范围和油气藏高度则主要受断层封闭性和封闭程度的控制,油气分布规律受伸展构造所伴生的各种断块群构造型式的控制。

| Abstract: | Reservoir types in the complex fault block oilfield in the northern slope of Biyang depression mainly are fault nose, fault block and fault plus lithologic reservoirs. Hydrocarbons mainly accumulate in the fault nose block of the nose structure. Analysis on the controlling factors of hydrocarbon accumulation in the study area reveals that inherited nose structures control the direction of hydrocarbon accumulation and abundance, while the oil - bearing area and the height of hydrocarbon column are mainly controlled by sealing capacity and degree of faults, and hydrocarbon distribution patterns are under the control of the structural modes of various fault block groups associated with elongated structures. |
