alogue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Palogue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，Ya bus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 stud

y 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 5thorder 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. 
