摘要： 利用层序地层学理论，对印尼J区块古近系—新近系的层序地层和沉积相特征进行了研究。古近系—新近系可以分为7个中期基准面旋回（SQ1SQ7）和17个短期基准面旋回。SQ1SQ7沉积时期，沉积环境从陆相河流环境逐渐过渡到三角洲环境和浅海环境，再到河流环境，为一完整的水进-水退旋回。中下部层序上升旋回占主体，属海进式沉积组合序列；上部层序下降旋回占主体，多为海退式沉积组合序列。结合层序特征，指出区块西部凸起带SQ5旋回的浊积砂体、基底风化壳、碳酸盐岩台地和东部斜坡带的下切谷为区块的有利勘探区带。研究结果对该盆地的石油勘探具有指导意义。

Abstract:

Based on the theory of sequence stratigraphy，the characteristics of sequence stratigraphy and sedimentary facies characteristics in J block，Indonisia，are

studied.The formations can be divided into 7 middleterm base level cycles （SQ1SQ7） and 17 short term base level cycles．From SQ1 to SQ7，the sedimentary

environment changed from nonmarine fluvial facies to transitional delta facies then neritic facies，eventually fluvial facies，forming a whole set of transgression and

regression cycle.Sequence stratigraphy can be divided into two series：the lower and middle parts are dominate rising cycle，which belongs to typical transgression series；

the upper is dominate descanting cycle，which belongs to regression series.At last，it is pointed out that the prospecting targets are the turbidite sandstone in the SQ5

and the weathered crust，the carbonate platform and the degrading valley on the downslope in the east of the platform.The conclusions are useful for petroleum exploration

in this basin.

Key words: sequence stratigraphy, base level cycle, sedimentary facies, favorable explorative area, J block of Indonesia
