摘要
塔中古隆起具有复式成藏、普遍含油、斜坡富集的油气分布规律;多期构造演化与成藏配置形成志留系-石炭系披覆碎屑岩构造与岩性油藏、上奥陶统沉积相控礁滩型油气藏、奥陶系风化壳型油气藏、寒武系白云岩岩性型油气藏等4大勘探领域。下古生界碳酸盐岩是塔中大油气田的主要勘探方向,下奥陶统风化壳与寒武系白云岩是下一步油气勘探的重点领域。
Tazhong uplift is characterized by complex petroleum accumulation, generally bearing oil, enrichment in slope. Its multi-stage structural evolutions and petroleum accumulations/assemblages form Silurian-Carboniferous drape clastic structural-lithologic reservoir, Upper Ordovician sedimentary facies controlling reef reservoir, Ordovician weathering crust reservoir and Cambrian dolomite lithologic reservoir, which are as four major exploration domains. Lower Paleozoic carbonate reservoir is a main target for exploration in Tazhong large oil-gas field. Lower Ordovician weathering crust and Cambrian dolomite will be next significant domains for further prospecting.
