摘　　要：Palogue油田是中西非地区规模最大的整装油田,为了合理编制该油田的开发方案,对Pa-logue油田Yabus-Samma组开发层段开展了层序地层学研究,进行了层序划分与对比,指出,Yabus组和Samma组属于1个二级层序内的2个三级层序,从Yabus组到Samma组上部可划分为3个四级层序,自上而下命名为SQ1、SQ2和SQ3,其中SQ1还可进一步细分为3个五级旋回,自上而下为SQ1-1、SQ1-2和SQ1-3,SQ2可进一步细分为SQ2-1、SQ2-2和SQ2-3等3个五级旋回,SQ3进一步细分为SQ3-1和SQ3-2等2个五级旋回,五级旋回与砂层组基本对应;这一划分与对比结果为合理开发该油田提供了科学依据。Palogue field is the largest field in Middle-West African. In order to do a reasonable field development plan, authors have finished sequence stratigraphy study and correlation between Yabus and Samma Formations. It shows the studied formations belong to two 3rd-order sequences and can be divided into three 4th-order sequences, which are named SQ1, SQ2 and SQ3 from top to bottom. The largest flooding surface of the formations is in SQ2. SQ1 is subdivided into three 5th-order sequences named SQ1- 1, SQ1-2 and SQ1-3; SQ2 is subdivided into three 5th-order sequences named SQ2-1, SQ2-2 and SQ2 3; SQ3 is subdivided into two 5th order sequences named SQ3-1 and SQ3-2. The 5th-order sequences correspond to sand zones.
