SEDIMENTARY EVOLUTION OF RIFT BASINS IN SULAWESI ISLAND REGION, INDONESIA AND ITS CONTROLS ON HYDROCARBON GEOLOGICAL CONDITIONS
-
摘要:
为了揭示印度尼西亚苏拉威西岛周缘裂谷盆地油气地质条件的差异性，有效指导该区的油气勘探，在综合现有勘探研究成果的基础上，从构造演化分析入手，系统分析了该区沉积演化特征及其对烃源岩和储盖组合的控制作用。结果表明，古新世—始新世的沉积相带控制了有效烃源岩的岩性和发育区，在断陷处形成了湖沼相、潮坪—潟湖相泥岩、煤系等类型的烃源岩；不同时期差异性的沉积充填形成2类储盖组合；苏拉威西地区西部河流—三角洲相控制形成了物性良好的碎屑岩储盖组合。晚中新世—上新世，台地—陆棚相控制形成了区域内最为重要的碳酸盐岩储盖组合，尤其台地和台地边缘的生物礁储层，物性优良，已获得重要发现，是今后该区油气勘探的重点关注目标。
Abstract:Sedimentary evolution characteristics of the rift basins in the Sulawesi Island Region and their effects on source rocks and reservoir-cap associations are studied comprehensively by this paper, in order to reveal the hydrocarbon accumulation conditions. The results suggest that the sedimentary facies of the Paleocene to Eocene controlled the lithology and distribution pattern of effective hydrocarbon source rocks. The source rocks are dominated by mudstone and coal of lacustrine to swamp facies with tidal flat and lagoon facies found in sags. There are two kinds of reservoir-cap associations. The Paleocene and Eocene river-delta facies in the west part of Sulawesi formed the clastic rock association with good petrophysical properties, while the Late Miocene to Pliocene shelf platform facies formed the most important carbonate rock association. Especially, the reef reservoirs with excellent properties occur on the platform or the border of platform. So far important discoveries have been made in the rift basins which has become the most important target for oil and gas exploration.
