摘要
自 2 0 0 1年以来 ,塔河油田南部下奥陶统一间房组的油气突破证实了对存在似层状储集体的推测。加里东期表生岩溶和深溶作用的发育及其在成藏中的作用 ,启发人们应以网络状和似层状储集体并重的思路 ,以“大岩溶”(成藏过程中多期表生和深溶岩溶 )和“大隆起”(与最大侵蚀期侵蚀基准面以上的整个古隆起及其演化过程 )
Oil and gas discovery in Yijianfang Formation of Lower Ordovician in Tahe Oilfield since 2001 proved the prediction about existence of like?_layered reservoir in this area.The existence of like?_layered reservoir of well_developed karstification caused by surface water and deep water during Caledonian orogeny as well as the affection of surface karst and deep karst on reservoir accumulation may be favorable for establishing and developing the idea that we would pay equal attention to both of network reservoir and like_layered reservoir.It would have been launched out the exploration of carbonate oil and gas reservoirs in Tarim Basin,based on the concept of 'large karst' including multi_stages surface and deep karsts formed during the reservoir_forming and 'large uplift',which might mean all paleo?_uplifts above the erosion base level in the strongest erosion stage and their evolution process.
