| 摘 要： | 为了探究车排子地区古近系层序地层发育规律和地层展布特征,应用经典层序地层学的原理和方法,通过对地震、钻井、测井和露头资料的综合分析,进行井间对比及井-震结合对比,详细研究了古近系层序的划分及特征。在车排子地区古近系识别出2个三级层序、4个体系域。研究区构造为一大型斜坡,可见小型坡折带,坡折带之下低位体系域发育,低位体系域与水进体系域由首次湖泛面分开,高位体系域不发育或不被识别。低位体系域以发育扇三角洲水下分流河道为特征,而水进体系域以滨浅湖相泥岩和粉砂岩沉积为主。地层发育受物源、古地形、气候和湖平面升降的控制,在研究区首次建立了古近系层序地层格架,并在层序地层格架内对研究区进行有利区带的预测,对车排子地区古近系地层寻找以岩性圈闭为主的非构造油气藏将起重要指导作用。

| Abstract: | To study the palaeogene growth and development,and distribution characteristics of sequence stratigraphic bed in Chepaizi area,the sequence stratigraphy is used with a discussion of its principle,method and technology.Based on composite analyses of seismic,drilling,well logging and outcrop data,together with interwell and log-seismic correlations,the palaeogene sequence stratigraphic classification and features are obtained with two third-scale sequences and four system tracts identified.It is shown that th... |
