| 摘 要： | 利用297口曲线、5口岩芯和三维地震等资料对三肇凹陷长10区块扶余油层断层特征及活动期次、沉积微相和油水分布规律等成藏因素分析表明:T2断层具有平面密集成带、剖面"似花状"组合特征,油源断层多为受控于基底断层继承性活动的密集带边界断层;扶余油层发育西南保康物源控制下的河控三角洲沉积体系,且垂向上发育先水退后水进的沉积演化序列,水退最大期位于扶I组7-扶II2小层.长10区块扶余油层成藏模式为三肇凹陷青一段源岩生成的油在超压作用下通过油源断层向扶余油层倒灌运移,然后在浮力作用下沿着东北向的河道砂体匹配油源断层组成的优势输导通道(断层密集带)向长10区块远距离侧向运移,又由于凹陷阶地区断层密集带说明水构造反转作用多表现为"隆中堑"特征,整体处于构造高部位,因此油主要聚集在断层密集带上.

| Abstract: | Through the analysis fault characteristics and movement period,sedimentary microfacies,oil-water distribution rule,which derived from 5 cores,297 well loggings and 3D-seismic,the conclusion is drawn that:T2 fault has the characteristics of dense belt in plane and flower-like in profile,and oil-source faults are border faults of dense belts,controlled by inherited movement of basement faults;the Fuyu reservoir develops fluvial-dominated delta controlled Southwest Baokang provenance,and the sedimentary evolut... |
