Abstract:
Based on the drilling data, strata and sedimentary facies, combined with the geochemical analysis of oil sample, seepage, core and outcrop, the development era, geochemical characteristics and sedimentary environment of source rocks in Sulawesi region, Indonesia were analyzed systematically. The results show that the main hydrocarbon source rocks of Cenozoic basins in Sulawesi region develop in Paleocene-Eocene, and generally contain coal or carbonaceous mudstones; the organic matter is partial humic with medium-good abundance, so that the source rocks have the ability to generate hydrocarbon; the sedimentary facies of Paleocene-Eocene source rocks is fluvial-swamp and flat-lagoon; the source rocks remain in the sags controlled by faults at rift stage; the thermal evolution of source rocks in the main parts is at the mature-overmature stage, so that the source rocks have the ability to provide sufficient hydrocarbon for the forming of hydrocarbon accumulation.
