distribution and exploration of Triassic,northern and central Tarim Basin

摘要: 三叠纪的塔里木盆地实际上被北部的沙雅隆起剥蚀区和中、西部的塔中剥蚀区分割成了4个互不连通的次一级盆地,其中塔北-塔中地区三叠系的残留面积大,构成了塔里木盆地三叠系分布的主体。三叠系是塔河油田的主要油气储层之一,自下而上分为3个储集层段下油组、中油组和上油组。与下油组和中油组相比,上油组的砂体更加发育,分布范围也更大,总体更向南推进。塔中早三叠世可形成自生自储油藏,因此塔中低凸起下三叠统仍有较好的勘探前景。Abstract: The TaYlm BaSln WaS dlVlded Into 4 ISOlated SUb-baSlnS by the 5haya Upllft In the nOYth andthe central Tarim denudation area in the center and the west during Triassic.In the northern and centralTarim Basin,the Triassic strata are preserved the most widely.Hydrocarbon in the Tahe Oil Field isfound mainly in Triassic,vertically divided into 3 reservoir layers:the bottom,the middle and the top.Sandbodies in the top layer generate better and distribute more widely than those in the middle and bot-tom layers,and advance to the south.Self-generated and self-accum Mated reservoirs might generateduring the early Triassic in the central Tarim Basin;hence the lower Triassic in the Central Tarim LowUplift has good potential for exploration.
