塔贝尔凹陷南屯组二段沉积体系平面展布特征
|
摘要
利用岩心、测井、地震、岩石薄片、分析化验等资料,对塔贝尔凹陷南屯组二段沉积微相进行了研究。研究结果表明,塔贝尔凹陷主要发育冲积扇、扇三角洲、近岸水下扇、湖底扇和湖泊沉积体系,其中扇三角洲沉积体系和湖泊沉积体系是研究区内最为发育的沉积体系类型。综合利用各种地震相分析、地震属性分析、砂岩百分含量、地层倾角测井、重矿物等资料,对塔贝尔凹陷的沉积体系平面展布进行了初步的预测。
Using core,logging,seismic data and rock flakes,and based on the results of laboratory analysis and other information,the microfacies of the Member 2 of the Nantun Formation from the Tarbell depression were studied.Results show that in the Tarbell depression,there developed various depositional systems,such as alluvial fan,fan delta,nearshore submarine fan,lake floor fan and lacustrine systems dominated by the fan-delta and lacustrine systems.Through seismic facies analysis,seismic attribute analysis,study of sandstone percentage,diplog,and heavy minerals,the spatial distribution of the above mentioned depositional systems were presented in this paper.
