摘　　要：印尼SP区块西北部的沉积充填可以划分为两套二级层序(即古近纪断陷层序和新近纪坳陷层序)和6套三级层序。古近纪断陷层序形成于盆地裂谷期,主要发育湖相沉积,沉降中心位于工区的西北部;新近纪坳陷层序形成于盆地的坳陷期,主要以海相沉积为主,沉降中心转移到工区的东南部。本区主要发育3套生储盖组合,其中断陷层序发育两套,坳陷层序发育一套。通过对地震资料和石油地质条件进行综合分析,对本区的勘探目标进行了优选。最新的钻探结果表明下部断陷层序取得了有意义的油气发现。The sedimentary filling northwest of Indonesia SP Block can be divided into two second-order sequences (i.e. Paleogene rift sequence and Neogene depression sequence) and six third-order sequences. The Paleogene rift sequence, which consists of lacustrine sediments, developed at the rifting stage of the basin. Its subsidence center is located in the northeast part of the research area. The Neogene depression sequence, which mainly consists of marine sediments, developed in the downwarping stage of the basin. Its subsidence center shifts to the southwest part of the research area. There are three associations of source-reservoir-cap rock in the block, of which two developed in the rift sequence and one in the depression sequence. The exploration targets are selected on the basis of the comprehensive analysis of seismic data and petroleum geological conditions. The latest drilling results show that significant oil and gas discoveries have been obtained in lower rifting sequences.
