| 摘 要： | 通过三维地震资料解释,结合区域地质背景及层序发育、沉积充填演化特点,对辽河滩海地区西部凹陷古近系岩性和地层圈闭的形成条件及发育模式进行了研究。结果表明,研究区发育砂岩透镜体圈闭和地层超覆圈闭,其中砂岩透镜体圈闭可分为低位浊积扇圈闭、高位滑塌扇圈闭和近岸水下扇圈闭。沉积坡折和断裂坡折是各体系域中岩性、地层圈闭砂体发育的主要条件,岩性、地层圈闭发育模式以低位体系域及高位体系域发育透镜体圈闭、湖侵体系域发育地层超覆圈闭为主。

| Abstract: | By means of interpretation on 3D seismic data and referring to the pattern of the sedimentary sequence development and deposition history in the existing reference concerning the west sag of the Liaohe depression beach,the paper manages to find out the forming condition and contribution model of the lithologic and stratigraphic traps occurring in the urea.The paper points out that there are two lithologic and stratigraphic traps,stratigraphic overlap trap and sandstone lenses trap in the study urea,and the ... |
