断裂控油气规律理论研究现状与进展

The Research Status and Advances of Theory About oil Control by fault

断裂构造是含油气盆地多种构造类型中最常见的一种,它不仅控制了盆地内沉积建造和层序发育,而且还直接或间接地控制着盆地内烃源岩、储集层、圈闭发育特征和油气的运移、聚集及油气藏的分布,只是不同级别不同性质的断裂在时空上对油气藏的形成和分布的控制作用则不相同。目前,关于断裂控油气规律的研究主要集中于断裂坡折带理论、断裂封闭性理论和断裂幕式活动理论三个方面,断裂坡折带理论集中研究同沉积断裂对沉积层序的控制,断裂封闭性理论和断裂幕式活动理论集中研究断裂活动与油气运聚关系的研究。

The fault structure is the common structural styles in the petroliferous basins, it control the sedimentary formation and the sequence development, also control the development of the source and the reservoir and the trap directly or indirectly, also control movement and gather of oil and gas, only the dif- ferent grades faults act as the different reactions. At present, the theory about oil control by fault mainly focus on the fault slope break and the fault sealing and the episodic activity, the fault slope break focus on the sedimentary sequence, the fault sealing and the episodic activity focus on the relations between the fault movement and the gather of the oil and gas.
