By applying OBMI imaging logging technique to a sedimentary study in Block S,the stratigraphic occurence,the provenance direction and the water energy are determined,and it is concluded that the regional sedimentary system mainly consist of deep-water mudstones and turbidite deposits with various sizes.
利用OBMI成像测井技术在S区块开展了沉积研究,确定了地层产状、物源方向及水体能量大小,明确了区域沉积体系主要为深水泥岩沉积及不同规模的浊流沉积;结合弹性波反演砂体平面分布及连井剖面对比,分析了A构造浊流沉积水道物源供给的方向及所形成的朵叶复合体展布特征,为该区有利目标评价提供了依据。
