渤南洼陷沙四上亚段浊积体沉积相划分

简述了胜利油田渤南洼陷沙四上亚段地质特征，综述了浊积岩内涵及其形成序列和模式。对渤南洼陷6口井沙四上亚段沉积相、微相进行了研究，从深水环境的岩性标志、密度流成因的岩石构造标志、浊积成因的粒度分布特征、地震和测井响应及适宜的形成条件等五个方面论证在洼陷带半深湖相、深湖相沉积背景下发育了湖底扇及远源砂砾岩透镜体，分析了渤南洼陷沙四上亚段沉积相。

Sidimentary Facies Classification of Turbidite of Upper Part of the Shasi Member in Bonan Sag, Shengli Oilfield

This paper presents briefly the geological features, describes the turbidite and its sequences and styles and studies the sedimentary facies and microfacies of the upper part of the Shasi member in six wells in Bonan sag. It is demonstrated from lithology of deep water, rock structure of density flow origin, grain distribution of turbidite origin, seismic and well logging responses and proper forming conditions that under the background of the deep lacustrine and semideep lacustrine facies deposits develops sublacustrine fan and far glutinite lens.
