摘要： 中苏门答腊盆地是一个发育在巽他克拉通陆块边缘上的弧后裂谷盆地,盆地内油气资源非常丰富,主力烃源岩为古近系Pematang 群Brown Shale 组的湖相页岩,主要储集层为Sihapas 群河流-三角洲相砂岩,其上覆的Telisa 组页岩是盆地的区域性盖层。盆地内具有3 种烃源岩相：深湖相、浅湖相和含碳沼泽相,湖相易于生油,含碳沼泽相易于生气和凝析油。盆地的西北部及海上地区是下一步勘探的重点和目标。

Abstract: Central Sumatra basin is a back-arc rift basin developed along the edge of the Sunda craton. The basin is very rich in oil and gas resources, the lacustrine shales of Brown Shale formation of the Pematang group of the Paleogene are the principal source rocks, the fluvial and deltaic sandstones of the Sihapas group are the main reservoirs and the overlying shales of the Telisa formation are the main seals in this basin. Essentially there are three source rock facies of the Pematang group, they are deep lacustrine facies, shallow lacustrine facies and carbonaceous marsh facies. The lacustrine facies is oil prone, the carbonaceous marsh facies is gas and condensate prone. The northwestern flanks and offshore in Central Sumatra basin are the targets for future petroleum exploration.

Key words: Central Sumatra basin, rift basin, lacustrine source rock, stratigraphic trap
