Sequence stratigraphy and sedimentary system of cainozoic in Papuan Basin
摘要
Abstract
In order to provide theoretical basis for Papua basin Cenozoic exploration, based on the comprehensive analysis of the work area drilling logging and combined with the 2D seismic data, the sequence stratigraphy and sedimentary system of Cainozoic in Papuan basin were systematically researched. And its plane distribution characteristics were studied, the hybrid sedimentary model of clastic rocks and carbonate rocks in basin were extracted. The results show that Papuan basin develops eleven 3rd-order sequences in Cenozoic, which contain four 3rd-order sequences in Palaeogene, six 3rd-order sequences in Neogene and one 3rd-order sequences in Quaternary. With the sequence stratigraphic framework, it develops the sedimentary systems of carbonate rocks and delta. The reef limestone of Mendi group (Esq2—Esq3 sequences) and the overlying strata Darai group (Nsq1—Nsq3 sequences) form local assemblages, the biological reef limestone of Darai group (Nsq1—Nsq3 sequences) and its overlying former delta Orubadi group (Nsq4—Nsq6 sequence) mudstone are the major reservoir-seal assemblages of Papuan basin in Cenozoic.关键词
