摘　　要：利用岩心、钻井、测井、分析化验等资料,对牛庄洼陷东坡沙四上亚段储层沉积相、微相特征等进行研究。研究结果认为,牛庄洼陷东坡沙四上亚段纯上次亚段沉积时期主要发育2种沉积相类型,即北部物源体系控制下的湖底扇沉积和南部物源体系下的三角洲前缘滑塌浊积扇沉积,储层主要为湖底扇、滑塌浊积扇的辫状水道微相沉积,其中湖底扇为该区最主要的沉积类型。根据不同沉积微相测井响应特征对沉积相在平面上的分布特征进行了分析,并对研究区沉积模式和储层分布控制因素进行了总结,对该区下步勘探开发具有一定的意义。Based on core observation,drilling,logging and analysis data,the sedimentary facies and microfacies of upper Es4 reservoir on the east slope of Niuzhuang sub-sag are investigated.It is recognized that there are two major sedimentary facies:sublacustrine fan deposition controlled by the northern source system and delta front slumping turbidite fan controlled by the southern source system.The sedimentation of braided channel microfacies of sublacustrine fan and slumping turbidite fan often serve as reservoirs,with sublacustrine fan as the most important type of sedimentation in this area.Based on the log response of different sedimentary microfacies,the distribution of sedimentary facies is analyzed,and the sedimentary pattern and reservoir distribution are generalized for the study area.
