摘要 基于地震地质解释,根据断裂带发育的位置、产状及构造样式,将琼东南盆地深水区中央坳陷自西向东划分为3个断裂体系:乐东—陵水伸展南倾调节断裂体系、北礁—松南—宝岛伸展北倾调节断裂体系以及宝岛—长昌张扭走滑断裂体系。断裂体系控制了生烃凹陷的分布和储集砂体的发育,形成了多种类型的圈闭,提供了油气垂向运移的通道,有利于油气聚集成藏。陵水凹陷—北礁凹陷结合部圈闭发育带、宝岛凹陷南部断阶带、长昌凹陷西部圈闭发育带是有利勘探区带。 Based on seismic geologic interpretation, three series of fault systems are classified in Central Depression(deep water area) of Qiongdongnan Basin with integrated characteristics of faults position, attitude, morphology and structural types:(1) Ledong-Lingshui extensional S-trending fault system,(2) Beijiao-Songnan-Baodao extensional N-trending fault system and(3) Baodao-Changchang transtensional strike-slip fault system. The formation an d evolution of faults mainly control the distribution of hydrocarbon-generating depressions and the development of reservoir sand bodies, which provides various traps with major pathways favorable for hydrocarbon migration. It is believed that the favorable plays are located in the trap belt between Lingshui Sag and Beijiao Sag, the southern fault belt in Baodao Sag and the trap belt in the west of Changchang Sag.
