泌阳凹陷下二门地区南部核三上亚段层序地层特征及地层-岩性圈闭预测
|
摘要
综合应用测井、岩心、三维地震剖面等资料,分析南襄盆地泌阳凹陷下二门地区南部核三上亚段的层序地层特征及沉积相,在核三上亚段识别出3个三级层序界面,将核三上亚段分为3个三级层序,识别出4种主要的沉积体系:三角洲、扇三角洲、湖泊及深水重力流沉积体系。根据沉积相的平面展布及演化特征,结合地层-岩性圈闭成藏条件分析,提出了一个有利的勘探靶区。图9表1参11
Based on data of log,core and 3D-seismic,the sequence stratigraphy features and sedimentary facies of the stratum of Eh_3 upper member of Hetaoyuan Formation in the south of Xia'ermen Oilfield,Biyang Sag,are studied.Three 3-order sequence interfaces are recognized in the member.The authors divide the target layer into three 3-order sequences.There are four kinds of sedimentary systems identified in the target layer,including delta,fan delta,lacustrine,and deep lacustrine turbidity sedimentary systems.According to the plane distribution,evolvement features of the sediment system and the condition of stratum-lithology pool forming,an potential exploration prospect is proposed.
