| 摘 要： | 利用岩性、钻井、地震及露头资料,通过对该地区进行层序地层学分析和研究,根据层序界面的识别原则,把大民屯凹陷古近系划分为1个二级层序,两个三级层序.从单井相入手,结合地震相识别出大民屯凹陷沙四段主要发育扇三角洲湖泊沉积体系和近岸浊积扇湖相沉积体系,主要发育扇三角洲和湖泊沉积相,局部发育近岸浊积扇.在沉积体系研究的基础上,利用地震反演预测了有利的储集砂体的发育区. |

| Abstract: | The Palaeogene strata in the Damintun depression may be divided into one second-order sequence and two third-order sequences on the basis of lithologic,well logs,outcrops and seismic data.In the fourth member of the Shahejie Formation in the Damintun depression,the depositional systems include the fan-delta to lake depositional system and the nearshore turbidite fan to lake depositional system,and the sedimentary facies types consist of the fan-delta facies,lake facies,and locally nearshore turbidite fan facies.The favourable areas for hydrocarbon accumulation are delineated by means of seismic inversion based on the research of depositional systems. |
