摘　　要：对下刚果盆地研究工区进行高精度层序划分及深水沉积储层精细研究,通过高分辨率三维地震资料和钻测井资料,对深水水道储层进行精细的描述,可以得到如下认识:1)将研究区三级层序划分为2个体系域:下部的异地沉积体系域和上部的原地沉积体系域;2)运用多属性分析方法确定砂体发育区,沿层相干切片技术、RMS均方根振幅属性技术、三维可视化种子点技术、确定性储层建模技术、神经网络储层建模技术综合刻画水道边界,追踪不同期次的水道砂体,预测有利储层平面分布,对重点目标区储层分布进行了宏观预测。Bas-Congo basin is located in West Africal Continental margin basin with its important oil and gas origin of West Africal coast rift system. In Miocene series, it has good reservoir with industrial oil flow in recent years. Reveals the deep-water oil and gas exploration has good prospects in the study area at Miocene series. So it carded out high-resolution sequence division and sedimentary reservoir studies in work area. Through high-resolution in three dimensional seismic data and drilling and logging information on deep-water channel of fine reservoir description, we get following awareness： 1 ） Third-order sequence was divided into two systems in the study area：different depositional system tract at the bottom determine the development regional of sand, and original ; 2） Application of multi-attribute analysis methods can including along-layer slicing technologies, RMS mean square root amplitude technologies, visualization technology of seed, deterministic reservoir modeling technology, neural network reservoir modeling techniques integrated describe the waterway border, tracking different period of channel sand, predicting favorable reservoir＇s plane distribution and the macro-forecast to reservoir＇s distribution in key target area.
