| 摘 要： | 受NNE向同沉积断裂的影响，东海盆地丽水-椒江凹陷表现为伸展断陷型盆地。对该区断裂构造的追踪对比和计算机模拟结果显示：该地区控盆断层具有典型的分段式、幕式时空演化特点；在断层活动过程中，不同区段的断裂在倾向和走向方向上产生明显的差异性，形成一种过渡性构造即构造转换带；在构造转换带处隐伏圈闭和有利砂体是油气长期运移的有利指向，对油气藏的形成和分布具有重要意义。

| Abstract: | The Lishui-Jiaojiang sag is shown as a spreading fault basin under the control of the contemporaneous faults. After the comparison of regional structures and faults, and computation simulation, the results of fault modeling indicate that basin-controlled faults have features as stepwise active and episodic active. Within the period of faults activity, differences along the dip direction and strike direction were formed, and resulted in the transfer zones. At the location of the transfer zones, structural traps and favorable sand bodies are developed, profitable for the hydrocarbon migration, and become the promising area of oil gas accumulation. |
