摘　　要：在滨北地区扶杨油层青一段源岩发育及排油强度、青一段源岩超压发育及其分布和T2断裂发育及分布特征研究的基础上,对源岩、超压和断裂空间配置关系及扶杨油层成藏与分布的控制作用进行了研究,得到青一段源岩、超压和T2断裂空间匹配关系控制着滨北地区扶杨油层油藏的形成与分布.青一段源岩和超压空间匹配关系控制着滨北地区扶杨油层油气运聚成藏的区域,青一段源岩超压与T2断裂空间匹配关系控制着滨北地区扶杨油层油气运移聚集部位和层位.在此基础上,预测黑鱼泡凹陷南部、安达地区北部、齐家凹陷北部和明水阶地西南部是滨北地区扶杨油层油气勘探的有利地区,扶余油层是主要的油气勘探层位.Based on the study of development and oil-expulsion intensity of Qing-1 member in Fuyang oil layer in Binbei area, overpressure development of source rock and its distribution in Qing-1 member and T2 fracturing development and distribution characteristics, this paper studies the spatial allocation relation of source rock, overpressure and fracturing and its controlling effect on reservoir-forming and distribution of reservoirs in Fuyang oil layer. The result shows that the formation and distribution of reservoirs in Fuyang oil layer in Binbei area are controlled by the spatial matching relation among source rock, overpressure and T2 fracturing in Qing-1 member, the areas of hydrocarbon migration and accumulation in Fuyang oil layer in Binbei area are controlled by the spatial matching relation between source rock and overpressure in Qing-1 member, and the positions and horizons of hydrocarbon migration and accumulation in Fuyang oil layer in Binbei area are controlled by the spatial matching relation among source rock, overpressure and T2 fracturing in Qing-1 member. On this basis, it is predicted that the south of Heiyupao depression, the north of Anda area, the north of Qijia depression, and the southwest part of Mingshui terrace are the favorable areas for hydrocarbon exploration of Fuyang oil layer in Binbei area, and Fuyu oil layer is the major exploration horizon.
