摘　　要：通过岩心观察、岩矿特征分析和测井资料解释,对直罗地区长6储层沉积相进行了系统分析。研究认为该区主要发育陆相湖泊三角洲沉积体系,主要储集砂体为三角洲水下分流河道砂体和河口坝砂体,其砂体展布受双重物源控制,呈东北-西南向展布。主要有利储层分布在长6层下部的长63和长62段,对于指导该区下步石油勘探具有重要的意义。Through the core observation, the analysis of rock and mineral characteristics and the interpretation of logging data, Chang 6 reservoir sedimentary facies in Zhiluo oilfield were analyzed.The studies suggest that mainly developed delta sedimentary system of lake of land face,the underwater distributary channel and mouth bar sand body of delta are the main reservoir sand body,the spread of sand body is control by double source area, showing the northeast-southwest.The main advantage of reservori is spread in Chang 63and62 of the lower part of the Chang 6 reservoirs.The research has important significance to guide oil exploration in the area in the future.
