| 摘 要： | 东营凹陷西部沙三段进一步勘探重点为岩性圈闭,但对其沉积特征的认识还存在争议.在前人沉积特征研究基础上,从沉积相类型、物源体系、沉积相分布及沉积模式等方面重新认识该区的沉积特征.新认识包括以下几个方面:研究区发育有辫状三角洲、近岸水下扇、浊积扇、滑塌浊积岩、湖泊等几种主要沉积相类型；发育有南部金家、西部高青凸起和东南部等...

| Abstract: | Lithologic traps are the main play for the further exploration in western Dongying Depression.But the knowledge about sedimentary characteristics in this area is disputed.Based on the former views,sedimentary characteristics are re-identified through facies types,provenance systems,facies distribution and facies model.The new understandings are as follows.The main facies types are braided delta,near-shore sub-lacustrine fan,turbidite fan and lake.There are three provenance systems which are southern Jinjia,... |
