东岭地区登娄库组地层层序地层学特征
|
摘要
以层序地层学理论为基础,综合利用地震、录井、测井和钻井资料对东岭地区登娄库组地层的层序地层学特征进行分析.通过对该区登娄库组地层层序界面的识别和划分,认为东岭地区登娄库组地层为一超层序,可划分为上下2个三级层序;在此基础上,在各三级层序内部进行体系域界面识别和体系域划分.结果表明:该区下部层序为湖相层序,表现为扇三角洲-湖泊沉积体系;上部层序为河流相层序,辫状河道发育,充填一套河流相地层.构造因素和气候因素是决定登娄库组地层层序形成与特征的主要因素.在对各层序沉积相带展布特征研究的基础上,对砂体进行预测,并取得较好的预测效果.
Guided by the sequence stratigraphy theory,we have analyzed the sequence stratigraphy feature of the Denglouku formation in Dongling area depending on the comprehensive utilization of seismic data,well logging data and well drilling data.We can conclude that the Denglouku formation is a super sequence containing two third order sequence depending on the recognition and division of its sequence boundary.We have also distinguished the system tract boundary and have divided the system tract inside in third order sequence.Research shows that the lower part sequence on that area is the lacustrine sequence,which shows for fan-delta—lake depositional system;and the upper one is the fluvial facies sequence in which the braided channel develops,and it fills a set of the fluvial facies stratum.We think that the tectonic factor and the climate factor are the major factors which decide the formation and the characteristic of the sequence stratum in that area.On the basis of the research of sedimentary facies distribution,we have forecast the thickness of the sandstone,and have obtained fairly good predictive effect.
