珠江口盆地陆丰凹陷中生界的发现及石油地质意义

通过对珠江口盆地陆丰凹陷东部地区的构造、断裂发育、地震反射结构、地层产状、地震反射频率等特征进行分析,并与已证实的新近纪洼陷进行详细对比和研究,首次提出陆丰凹陷东部发育中生代残留洼陷。通过与周边已证实的中生代坳陷石油地质条件的类比,认为陆丰凹陷的中生代残留洼陷应具有一定的勘探潜力,能为陆丰凹陷下一步的油气勘探开辟一个新的领域。

Discovery of Mesozoic Sediments and It＇s Petroleum Significance in Lufeng Sag, Pearl River Mouth Basin

By illustrating structure,fault,seismic reflection configuration,seismic attitude,and seismic reflection frequency,as well as comparing it with the Neogene sags in the eastern region of Lufeng sag,Pearl River Mouth basin,it is proved that the eastern development of Lufeng sag is a residual sag in Mesozoic.The comparing results suggest that the Mesozoic residual Lufeng sag as a new exploration field should have a certain exploration potential.
