摘　　要：为了描述塔里木盆地塔中地区碳酸盐岩储层特点,以地震、测井信息为基础,利用叠前双相介质反演方法预测溶蚀孔洞的分布。塔中地区下奥陶统潜山风化壳及内幕发现油气藏,表明奥陶系碳酸盐岩中的古岩溶是该区重要的油气勘探目的层系,揭示了该区古岩溶储层良好的油气勘探前景,并证明叠前双相介质属性反演方法是预测碳酸盐岩储层油气藏的有效手段。In order to describe the characteristics of carbonate reservoirs in Tazhong area in Tarim Basin,this paper uses two-way media inversion method to predict corroded caverns distribution basing on seismic and logging data.Oil and gas reservoirs are discovered in weathered shell and inside story of buried hill in Lower Ordovician in Tazhong area,showing that ancient karst in Ordovician carbonate is the main target layer system of oil and gas exploration.This indicates a good exploration potential of the ancient karst in this area,and proves that two-way media attribute inversion is an effective method for prediction carbonate reservoirs.
