| 摘 要： | 断层是惠民凹陷南部地区油气运移的主要通道,主要油源断层的输导与封闭性决定了该区油气富集程度.利用断裂活动期与油气运移期的匹配关系,研究了该区主要断裂输导与封闭性能的时间变化规律,活动期断层对油气起输导作用,静止期其输导与封闭性能受到很多地质因素影响.采用定量方法对该区夏口断层、营子街断层、玉皇庙南断层的封闭性进行单因素研究,并利用模糊评价方法,分别对其进行了综合评价.结果表明,该区断层静止期,沿断层走向,其输导与封闭性能具有一定的变化规律.沿夏口断层走向,夏23--夏37井区附近封闭性差,夏37井区附近封闭性中等,夏37--夏224井区西侧封闭性较差,夏224--夏223井区附近封闭性中等,夏口断层的最东段封闭性变差;营子街断层自西向东封闭性由差变好;玉皇庙南断层的封闭性整体较好,但是断层东、西段封闭性好,中段封闭性差.该区断层输导与封闭的主控因素有断层活动性及断距、断层走向与倾角、泥岩涂抹系数. |

| Abstract: | Fault is the main pathway of hydrocarbon migration in south region of Huimin depression,and also can form the associated reservoirs.Sealing and transporting capability of the main oil source fault determines the extent of hydrocarbon accumulation in this area.In this paper,by using the matching relation between the fault activity periods and oil-gas migration periods,we can find variation of main faults in terms of transporting and sealing capacity along with time in this area.The fault can seal oil-gas dur... |
| Keywords: | fault sealing and transporting capability main controlling factors fault activity times migration period south region of Huimin depression |
