海相碳酸盐岩储层是南黄海盆地崂山隆起中—古生界重要的油气储层，由于钻井少，储层非均质性强，地震储层预测研究是油气勘探的重点和难点。以南黄海石炭系—下二叠统碳酸盐岩为例，通过分析CSDP-2井生物碎屑灰岩储层的岩石物性及井-震响应特征，发现生物碎屑灰岩声波阻抗高于纯灰岩以及碎屑岩的声波阻抗，低λρ具有较好的岩石物性特征，针对这种特点，采用叠前同时反演方法对孔隙型碳酸盐岩储层的岩性和物性进行预测。预测结果表明南黄海崂山隆起石炭系—下二叠统生物碎屑灰岩储层比较发育，横向不连续且具有较强的非均质性，位于古高地储层物性发育较好，其成因是由于受印支构造运动，上覆地层抬升到地表遭到暴露，加上淡水淋滤溶蚀作用，在一定程度上提高了碳酸盐岩储层的次生孔隙，形成了钻井岩心所揭示的储层特征，因此，高孔隙度的孔隙型碳...
