【摘要】：为弄清留楚地区断裂控藏规律,在明确油源断裂的基础上,采用断面埋深等值线法刻画出油源断裂优势运移通道,结合烃源岩供烃能力和油气分布特征,分析了断面优势运移通道有效性的差异及其对油成藏分布的控制作用。结果表明,留楚地区油源断裂为明化镇组沉积末期活动的Ⅲ型、Ⅴ型和Ⅵ型断裂,凸面型断面为其优势运移通道;断面优势运移通道有效性按照其沟通烃源岩级别的不同分为有效、较有效和低效3个等级;断面优势运移通道的分布控制了油气的平面和纵向分布,断面优势运移通道有效性等级控制了油气的富集程度。研究成果对留楚地区下一步勘探具有重要指导意义。
[Abstract]:In order to make clear the rules of fault and reservoir control in Liuchu area, on the basis of clear understanding of oil source faults, the dominant migration channels of oil source faults are described by using the section buried depth isoline method, and the hydrocarbon supplying ability and hydrocarbon distribution characteristics of source rocks are combined. The difference in the effectiveness of the dominant migration channel and its controlling effect on the distribution of oil accumulation are analyzed. The results show that the oil-source faults in Liuchu area are 鈪，
