中文摘要:为了研究渤海湾盆地冀中坳陷大柳泉地区F8断裂附近油气分布规律,在F8断裂不同时期输导油气通道及分布特征研究的基础上,通过F8断裂活动期伴生裂缝通道及停止活动后凸面脊通道输导油气能力评价,结合F8断裂附近油气分布规律,对F8断裂不同时期输导油气能力对成藏贡献进行了研究,结果表明:F8断裂第二条伴生裂缝通道输导油气能力明显强于第一条伴生裂缝通道输导油气能力,第二条伴生裂缝通道输导油气能力从沙四上亚段(即古近系沙河街组四段上亚段,余类推)至沙三中亚段增强,从沙三中亚段至沙三上亚段减弱,而第一条伴生裂缝通道输导油气能力从沙四上亚段至沙三中亚段增强较慢,从沙三中亚段至沙三上亚段输导油气能力增强较快。F8断裂第1、2条凸面脊通道输导油气能力明显较第3、4条凸面脊通道输导油气能力要强,第1条凸面脊通道输导油气能力从沙三下亚段至沙三中亚段明显减弱,但从沙三中亚段至沙三上亚段变化不大,第2条凸面脊通道输导油气能力从沙四上亚段至沙三中亚段增强,从沙三中亚段至沙二段减弱,从沙二段至馆陶组快速增强;第3条凸面脊通道输导油气能力由沙四上亚段至沙三下亚段变化不大,从沙三下亚段至沙三上亚段快速增大,从沙三上亚段至沙二段变化不大,从沙二段至馆陶组快速减小。第4条凸面脊通道疏导油气能力从沙三下亚段至沙三上亚段快速增加,从沙三上亚段至沙二段快速减小,从沙二段至馆陶组减小缓慢。F8断裂活动期伴生裂缝通道输导油气能力对成藏的贡献无论是在平面上还是在剖面上均大于停止活动后凸面脊通道输导油气能力对成藏的贡献。

Abstract:In order to study the distribution pattern of hydrocarbon near the Fault F8 in the Daliuquan area,based on the study of hydrocarbon transport channels and distribution characteristics of the Fault F8 in different periods.Methods: By evaluating the associated fracture channels during the active period of the Fault F8 and the hydrocarbon transport capacity of convex ridge channels after the cessation of activity,and by combining the hydrocarbon distribution pattern near the Fault F8,the contribution of the transport capacity to the reservoir formation in different periods.Ressults:The results show that: The hydrocarbon transport capacity of the second associated fracture channel of the fault is stronger than the first associated fracture channel.The hydrocarbon transport capacity of the second associated fracture channel is enhanced from the upper sub-member,4th Member,Shahejie Formation,Paleogene (Es4) to the middle sub-member of Es3 and weakened from the middle sub-member of Es3 to the upper sub-member of Es3.The hydrocarbon transport capacity of the first associated fracture channel enhanced smaller from the upper sub-member of Es4 to the middle sub-member of Es3,while the hydrocarbon transport capacity enhanced greatly the middle sub member of Es3 to the upper sub member of Es3.Conclusions:The first and second convex ridge channel of Fault F8 has stronger hydrocarbon transport capacity than the third and fourth convex ridge channel.The first convex ridge channel has a significant decrease from the upper sub-member of Es4 to the middle sub-member of Es3,but there is little change from the middle sub-member of Es3 to the upper sub-member of Es3.The second convex ridge channel has an increase from the upper sub-member of Es4 to the middle sub-member of Es3 but is weakened from the middle sub-member of Es3 to the upper sub-member of Es3.The third and fourth convex ridge channels are gradually enhanced from the upper sub-member of Es4 to the upper sub-member of Es3.Whether on the plane or the profile,the contribution of the hydrocarbon transport capacity of the associated fracture channel during the active period of the Fault F8 to the accumulation is greater than that of the convex ridge channel after the suspension of activity.
