摘要:

根据构造解释成果,并结合油气勘探实践,对渤海辽东湾坳陷的断裂联接特征及其对油气聚集成藏的影响进行了分析。辽东湾坳陷主要发育NE和NEE走向的伸展断裂、走滑断裂和伸展-走滑复合断裂,其中部分断裂通过硬联接和软联接方式发生了相互作用。根据断裂发育特征及其联接作用的表现形式,可将硬联接方式分为接力型、消减型和传递型3类,将软联接分为同向斜坡型、斜向背斜型和背向地垒型3类。辽东湾坳陷断裂及其联接作用对沉积体系发育、圈闭形成和储层质量改善等都产生了重要影响,有利于油气在断裂相互作用区聚集成藏。

Abstract:

On the basis of structural interpretation and hydrocarbon exploration,this paper addresses fault linkages and their control on hydrocarbon accumulation in the Liaodongwan Depression,offshore Bohai Bay Basin.The extensional,strike-slip and compound faults with NE and NEE strikes are predominant in the Liaodongwan Depression,and they inte-ract with each other by hard or soft linkages.According to the assemble patterns of faults and their linkages,the hard linkages of faults can be divided into three types:relaying,consumering and transferring.Similarly,the types of soft lin-kages involve synthetic ramp,convergent anticline and divergent horst.Faults and their interaction exerted important influences on depositional systems,structural traps and reservoir properties.The interaction zones of faults are the favorable objectives for oil and gas exploration in the Liaodongwan Depression.

Key words: fault, hard linkage, soft linkage, hydrocarbon accumulation, Liaodongwan Depression
