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
