Abstract:

斜坡是断陷和凹陷型盆地的重要构造单元,按其断裂发育程度和沉积厚度分为复杂斜坡和简单斜坡。松辽盆地西部斜坡为断裂不发育、平缓的简单斜坡,简单斜坡油气成藏有特殊性,表现在三个方面:一是简单斜坡的原油主要来自临近的凹陷,油气沿砂体以优势路径方式侧向运移,油气呈“线状”分布;二是简单斜坡大规模构造圈闭不发育,圈闭类型以地层、岩性和构造-岩性圈闭为主,其分布受构造带控制,超覆带发育岩性上倾尖灭圈闭,受规模较大的断层控制形成的鼻状构造带上发育断层遮挡和构造-岩性圈闭,不受断层控制的鼻状构造带主要发育构造-岩性圈闭。三是简单斜坡普遍受大气水的淋滤作用,由于游离氧的进入使原油遭受氧化降解作用而稠化,造成简单斜坡稠油分布普遍。这种成藏的特殊性决定了油气富集规律:只有位于油气运移路径上的圈闭才有成藏的可能。简单斜坡油气勘探方向是,在油气运移路径上寻找低幅度构造背景下的岩性油气藏(小规模)、规模较大断层附近寻找断层遮挡油气藏(中等规模)和地层超覆带上寻找岩性上倾尖灭油气藏(大规模)。
