摘　　要：90年代中期川东北部地区发现渡口河飞仙关组鲕滩气藏以来 ,开展了大量的储层预测工作 ,采用的主要技术是“亮点”技术。但随着勘探领域的扩大 ,勘探开发工作的进一步深入 ,该技术的应用受到了局限 ,主要源于岩性的影响 ,因为石膏同样会形成强反射特征 ,其次定性的“亮点”技术不能满足勘探生产中急需解决的储层“有无、厚薄、好坏、气水”方面的问题。文章根据综合分析已钻井测井试油资料指出 :鲕滩储层的地震响应特征主要表现为低阻抗特征的强反射特征。并运用地球物理手段提出了 ,针对鲕滩储层这种特殊岩性的储层识别技术 ,并在此基础上对储层进行量化预测。Since the discovery of oolitic beach gas pool in Dukouhe Feixianguan formation in northwest Sichuan district in the middle of 1990s, large amount of reservoir prediction work has been launched, the chief technique adopted is that of 'bright spot'. But along with the enlargement of exploration domain, and the further deepening of exploration and development work, application of this technique suffers limitation, mainly originating from lithological influence, because gypsum will similarly form strong reflection; secondly the qualitative 'bright spot' technique can't satisfy the much-needed settlement of such problems in exploration production as: 'presence or absence, thick or thin, good or bad, gas and water' etc of reservoir, therefore on the basis of comprehensive analysis of data of already conducted drilling, logging, and oil-testing, the paper has pointed out that the seismic response feature of oolitic-beach reservoir displays mainly to be a strong reflection feature with low impedance, and by utilizing geophysical means, has raised the reservoir recognition technique countering this special lithological oolitic beach reservoir, and on this foundation, conducted the quantification prediction for reservoir.
