摘要(Abstract)：

为提高葡北油田扶余油层复杂断裂区带构造解释精度,针对研究区井控程度低、发育多期微小断裂和断裂切割关系复杂等,根据高分辨率地震资料,运用变面积和变密度剖面显示、水平切片、相干体切片及相位谱分解等方法,完成葡61区块扶余油层精细构造和断裂分析.结果表明:新井构造误差小于5‰,准确识别5~10m圈闭高度的微幅度构造.扶余油层顶面构造特征形态为断裂切割背斜形成的、以地垒、地堑和断阶为主的局部断裂—构造圈闭.综合构造、断裂及砂体发育特征,在研究区优选1个Ⅰ类有利区块,面积为44.3km2;2个Ⅱ类有利区块,面积为82.4km2;5个Ⅲ类有利区块,面积为29.2km2.该研究结果对扶余油层开发具有一定的指导作用.

关键词(KeyWords)：扶余油层;复杂断裂带;水平切片;相干体切片;断裂分析;有利区块
