摘要：为了掌握三肇凹陷葡萄花油层油分布规律，应用石油地质油气成藏理论，在升平坡中隆和升西一徐家围子向斜葡萄花油层油藏类型及油分布规律对比研究的基础上，对造成升平坡中隆和升西一徐家围子向斜葡萄花油层油成藏特征差异性的成因进行了研究。研究发现升平坡中隆和升西一徐家围子向斜在油气藏圈闭类型上具有显著区别，升平鼻状构造背景下形成的断背斜和断块圈闭是其油藏的主要类型，升西一徐家围子向斜背景下形成的断层一岩性图团是其油藏的主要类型：油输导通道类型及其分布特征不同是升平坡中隆和升西一徐家围子向斜葡萄花油层油分布规律不同的根本原因，升平坡中隆葡萄花油层砂体中油侧向运移路径及分布控制着油在坡中隆上呈大面积分布，而升西一徐家围子向斜葡萄花油层油源断裂及其分布控制着油在断裂密集带内呈断续条带状分布。此研
究成果对于正确认识三肇凹陷葡萄花油层油气成藏规律及指导该地区油气勘探具有重要意义。关键词：源外坡中隆；向斜区；油聚集；差异性；成因分析

Abstract: In order to study the law of oil distribution of P oil layer in Sanzhao Depression, on the basis of the research about reservoir types of the central raised area of Shengping slope zone and Shengxi-Xujiaweizi synclinal region and distribution of oil and water, this paper studied cause of making oil accumulation difference of P oil layer in the central raised area of Shengping slope zone and Shengxi-Xujiaweizi synclinal region, applying the petroleum geology theory of forming reservoir. The result indicated that the type of trap caused by structural background is different in P oil layer in the central raised area of Shengping slope zone and Shengxi-Xujiaweizi synclinal region. Fault anticline and fault block traps formed under the background of Shengping nose structure is the main types of oil-gas reser-voir,fault and lithologic trap formed under the background of Shengxi-Xujiaweizi syncline is the main types of oil-gas reservoir. Oil con-ducting channel and its distribution characteristics difference are the root cause of the oil distribution regularity difference of P oil layer in the central raised area of Shengping slope zone and Shengxi-Xujiaweizi synclinal region. Oil of P oil layer in the central raised area of Shengping slope zone lateral migration path and distribution control oil in a large area distribution of the central raised area of slope. Oil source faults and distribution of P oil layer of Shengxi-Xujiaweizi synclinal region control oil with intermitent strip distribution in faults density. This research production is important to understand the law of forming reservoir and guide the exploration.
