| 摘 要： | 利用岩心、测井、古生物、地震属性和波阻抗反演资料,对辽东湾辽中凹陷J27区进行高分辨率层序地层分析,在东营组第二段底部中期旋回中,识别出面积约40 km2的大型低水位浊积扇岩性圈闭.此类圈闭烃源有机质丰度高,Ⅰ～Ⅱ型干酪根为主,储层测井平均孔隙度达27.5%,沟通烃源的断层较发育,多种地震属性分析表明其富含油气,具有良好的油气成藏条件,是该地区岩性油气藏勘探的重点领域.

| Abstract: | By using the data of cores,well logging,seismic attribute and wave impedance inversion,a high-resolution sequence stratigraphic analysis was carried out in block J27 of the Liaozhong depression,Liaodong Bay.A large low water turbidite fan lithologic trap with an area of approximate 40 km2 was discriminated in the middle term cycle at the bottom of Member 2 of Dongying Formation.The hydrocarbon source in this kind of trap is characterized by high-abundance organic matter and the kerogen is dominated by type ... |
