Evolution of lithofacies and paleogeography of Late Paleozoic and hydrocarbon resources potential analysis in Arctic area
摘要
Abstract
On the basis of the IHS databases and literature,the Late Paleozoic lithofacies and paleogeography of Arctic area are systematically studied.The lithofacies paleogeographic maps of three mainly geologic time (390 Ma ±,350 Ma ±.,270 Ma ±) are drew by using geographical information system software of ArcGIS.The petroleum characteristics and the hydrocarbon potential are briefly analyzed.Six types of paleogeographic units were identified in research area,including uplift-erosion facies.Abyssal facies,neritic facies,lacustrine facies,saltmarsh facies,alluvial facies.Sedimentary record deletion means uplift-erosion facies.Abyssal facies are largely comprised of mudstone;while neritic facies largely sediments carbonate,sand-mud or the combinations of sand-mud-carbonatite.Lacustrine facies are largely comprised of carbonate or the combinations of sandmud,saltmarsh facies are largely comprised of evaporate-carbonate combination,alluvial facies are comprised of the combination of conglomerate-sand-mud or sand-mud.The source rock,reservoir,seal mainly distributes in Devonian and Permian.The lithology of reservoir is sandstone and carbonate rocks.Seal is dominated by shale.Self-generation and self-storage are the primary pattern of reservoir in this region.The Barents Sea Platform Carboniferous formation,the formation of Timan-Pechora Basin in Devonian,the formation of Sverdrup Basin in Permian are important regions for hydrocarbon exploration.North of Kara Sea Basin,Laptev Sea Basin and East Greenland Basin are great potential for development of the region.关键词
