摘　　要：通过AVO近远道集叠加剖面振幅变化特征以及双相介质模型技术分析,对四川盆地南部嘉陵江组碳酸盐岩储层的含气性进行了分析研究,其中利用近远道叠加剖面振幅变化对比预测气层效果非常明显,预测的近远道叠加振幅对比平面分布图与区内多数已钻井的结果符合程度较好。该方法对嘉陵江组的天然气勘探有较大的实用价值。The gas attributes that are the south Sichuan Jialingjiang group carbonate storage layer are studied with amplitude changes of AVO angle stack section and double medium model technique. In addition, the better effect has achieved by the comparison of amplitude changes of AVO near-far angle stack section. The comparison map what prognosticated with near-far angle stack amplitude has preferably accorded with most artesian well. In a word, the method has more practicality value on gas exploration & development of Jialingjiang group.
