A区块内发育一系列的盐构造，盐构造与油气成藏关系密切。利用钻井和地震资料研究认为，A区块主要发育4种盐构造类型：龟背构造，棱形底辟，大型底辟和盐滚构造。在盐构造相关的各类圈闭中，棱形底辟相关各类圈闭油气最富集，其次是龟背构造相关圈闭。盐构造影响烃源岩分布、圈闭形成和分布及储层分布，同时盐构造活动提供油气运移通道。
A區塊內髮育一繫列的鹽構造，鹽構造與油氣成藏關繫密切。利用鑽井和地震資料研究認為，A區塊主要髮育4種鹽構造類型：龜揹構造，稜形底闢，大型底闢和鹽滾構造。在鹽構造相關的各類圈閉中，稜形底闢相關各類圈閉油氣最富集，其次是龜揹構造相關圈閉。鹽構造影響烴源巖分佈、圈閉形成和分佈及儲層分佈，同時鹽構造活動提供油氣運移通道。

A series of salt tectonic are developed in block-A. Salt tectonic has close relationship with hydrocarbon accumulation. According to the researches by using drilling and seismic data, four types of salt tectonic can be distinguished in block-A:turtles, prismatic diapirs, large diapirs and salt rolling tectonic. Different kinds of prismatic diapirs related traps are the richest in hydrocar-bon accumulation. Turtles related traps follow. Salt tectonics affect distribution of hydrocarbon mother rocks, traps and reservoirs, along with the foramtion of traps. Meanwhile, salt tectonic activities provide migration pathways.
