【摘要】 西伯利亚地台是俄联邦陆上最后一个油气储量丰富、勘探潜力巨大的区域,是东西伯利亚-太平洋输油管道的重要供油基地,是"西伯利亚力量"天然气管道的供气基地,亦是中国油企进入俄罗斯市场的重要战略选区。地台内的超大坳陷是烃源岩富集与沉积的最佳场所,大型古隆起及其斜坡带是油气聚集的有利场所。古隆起与上覆地层的不整合接触为大油气田的形成提供了良好条件。地台内,发育在古坳拉槽和裂谷盆地的里菲系、文德系黑色泥页岩和高碳泥岩是主要的烃源岩;地台内里菲系巨厚碳酸盐岩建造、文德系和下寒武统盐下陆源碎屑岩建造及碳酸盐岩建造,以及地台边缘前陆坳陷区发育的砂岩(二叠系-三叠系和侏罗系-白垩系)均为重要的油气储层;中寒武统膏盐岩层厚度大、区域分布稳定,是重要的盖层。中国北方震旦系与西伯利亚地台里菲系的时代大致相同,均具有巨厚沉积特点,在含油气建造方面具有一定的可比性,因此,研究西伯利亚地台油气地质特征,可为我国在深部找油及与俄罗斯的油气勘探开发合作,提供重要的参考信息。更多还原

【Abstract】 Siberian Platform owns abundant oil gas reserves which have a lower rate of exploration and great development potency.Siberian Platform is the absolute oil and gas source base for East Siberian-Pacific Ocean oil pipeline,Chinese branch pipeline of East Siberian-Pacific Ocean oil pipeline,and the east and west branch of the future Russian-Chinese natural gas pipeline.Black mud shale and high-carbon mudstone of Riphean period and Vendian period are the main source rocks which developed in the ancient aulacogen and rift basin within the Platform.Riphean thick carbonate buildup within the Platform,Vendian system and Lower Cambrian salt clastic fragment buildup and carbonate buildup,and the sandstone developed in foreland depression of platform edge(Permian-Triassic and Jurassic-Cretaceous)are the major oil and gas reservoirs.Cold Cambrian gypsums have thick strata,stable regional distribution,and is an important covering strata.Siberian Platform,containing gas structures,can be compared with Sinian system of northern China,essentially because of their common huge thickness.Petroleum-forming mechanisms and oil detection experience of old stratums in Riphean,Vendian,and Precambrian system in Siberian Platform provide referential experience for oil gas exploitation under old stratums in China.更多还原
