摘　　要：针对塔中地区碳酸盐岩储层埋藏深、非均质性强,地震资料信噪比低、分辨率低、多次波发育等特点,采用多域去噪、叠前去多次波、保持振幅处理、串联反褶积、浮动基准面叠前时间偏移等关键技术,形成了一套适合于碳酸盐岩缝洞型储层精细目标的处理方法和流程,改善了该区的地震资料品质和成像效果,为提高塔中碳酸盐岩储层预测精度和开展烃类检测提供了可靠的地震资料。Regarding some characteristics of carbonate reservoir, such as deep burial depth, significant heterogeneity, low seismic data signal to noise ratio, low resolution and developed multiples, the multi-domain noise elimination, pre-stack multiple elimination, amplitude preservation processing, series deconvolution and floating datum pre-stack time migration and other key techniques were adopted, a set of object-oriented processing method and flowchart which fit the fractured-vuggy carbonate reservoir was formed, as a result the data quality and imaging effects for the seismic data in this area were greatly improved, reliable seismic data were provided for more accurate reservoir prediction and hydrocarbon detection in Central Tarim Basin.
