摘　　要：Ek_2~2油组为孔西斜坡重点目的层系,含油范围广,油层分布稳定,目的层埋藏浅。为深入研究各物源的波及范围、砂体规模及展布特征,将孔西斜坡Ek_2~2油组分为上下两套砂层,以上砂组为研究对象,根据轻重矿物特征、砂体展布规律和地震反射特征等资料,对影响区内的多个物源位置、波及范围及砂体展布规律进行了系统研究,孔西斜坡Ek_2~2油组上砂组沉积物主要来自徐杨桥、孔店、沧市、舍女寺和叶三拨5个物源输入体系。Ek22 member is the main oil-bearing strata in Kongxi slope because of its shallow buried depth,stable distribution and wide oil-bearing area.In order to carry out an indepth study on provenance scope,sand body scale and distribution regularities,the oil groups of Ek22 reservoir in Kongxi slope were divided into the upper set and the lower set,and the upper set was considered to be the study target.Based on characteristics of light and heavy minerals,sand body distribution regularities and seismic reflection characteristics,a systematic study on the influencing factors which affected the provenance location was carried out.The results indicate the detritus in the study area are believed to come mainly from the Xuyangqiao,Kongdian,Cangshi,Shenvsi and Yesanbo.
