| 摘 要： | 滨里海盆地东缘中区块北特鲁瓦油田的碳酸盐岩储层单层厚度小,同时具有缝洞储集空间、基质孔隙储集空间的双重介质储层特征,造成储层与非储层的常规地震属性(如振幅属性、波阻抗等)差异小,采用多维属性交会分析方法预测的储集体高产发育带与实际钻探结果误差较大。为此,本文利用频谱积分属性技术评价碳酸盐岩储层,通过加载基础资料(地震数据、层位、井等)、数据重采样、选择检测时窗、确定频率敏感段、提取相关数据等步骤评价碳酸盐岩储层,基于地震波通过流体储层时,出现"低频共振、高频衰减"的动力学特征,利用油气存储空间属性预测碳酸盐岩储层有利高孔、渗带,利用可动油气孔隙度—产能交会图预测碳酸盐岩储层高产带,利用研究成果指导油田滚动勘探,应用效果较好。

| Abstract: | Within thin carbonate reservoir,there is dual medium feature of both fracture-caves and matrix reservoir space in the North Teruwa Field of the eastern fringe of Caspian middle block.There are tiny difference of seismic attributes(amplitude and impedance,etc) between reservoir and non-reservoir,and the difference is evident between actual drilled results and the high-production zones predicted by multiple attributes analysis.In this paper,carbonate reservoirs are evaluated with frequency-spectrum integratio... |
