摘要: 根据野外露头、钻井、测井和地震资料,将塔北隆起泥盆系东河砂岩划分为一个三级层序,该层序具有明显的从水进到水退的沉积结构,中部为最大水进期,自下而上可明显地划分为海侵体系域和高位体系域。东河砂岩主要形成于浪控滨岸环境,主体岩性为岩屑石英砂岩,具有较高的成分和结构成熟度,发育交错层理、平行层理、冲洗层理、块状层理以及生物扰动构造。根据地震剖面上的叠瓦状前积结构和岩芯观察,认为在东河20井,赛克低凸起和草4井附近发育有浪控三角洲体系。

Abstract: Based on the outcrop,borehole,logging and seismic data,the Donghe Sandstone in Tabei Uplift is defined as a thirdsequence stratigraphy.This sequence has an obvious sedimentary cycle from transgression to regression,and can be divided into transgressive system tract and highstand system tract.The major lithology of the Donghe Sandstone is detritus quartz sandstone which has a high composition and texture maturity.It develops cross bedding,parallel bedding,swash bedding,massive bedding and bioturbate structure.According to the progradational seismic facies and the core observation,wavedominated delta depositional system is developed in well Donghe 20,Saike Uplift and well Cao 4.

Key words: Donghe Sandstone, sedimentary facies, wavedominated delta, Tabei Uplift, sequence stratigraphy 
