【摘要】 潮汕坳陷位于珠江口盆地南部,是珠江口盆地油气勘探的新领域.中生界地层特征和油气勘探潜力是目前工作重点.本文分析了潮汕坳陷区域重力、磁异常特征及地震地质规律,提出潮汕坳陷是衔接东沙群岛和西沙群岛两个构造单元的构造过渡带的观点,同时盆倾断层控制了中生界发育与分布.根据潮汕坳陷地震等地球物理特征及地质规律,结合前人研究结果,分析了该区的油气勘探潜力.更多还原

【Abstract】 Chaoshan depression located in the south of the Zhujiang river mouth basin,it is now becoming a new field of exploration for oil and gas of Zujiang river mouth basin.The focus of work is aim to the Mesozoic group features and hydrocarbon exploration potential at present.The text analyse region characteristic and rule of gravity and magnetism annormity in Chaoshan depression,conclusion think that the Chaoshan depression is tectonic transition belt of join two tectonic element about the dongsha islands to the xisha islands,the fault of turning towards the basin control growth of the Mesozoic group.According to characteristic and rule of seismogeology in the chaoshan depression,the thesis integrate oneself with research result by our predecessors,put forward hydrocarbon exploration potential in Chaoshan depression.更多还原
