摘要： 塔中Ⅰ号坡折带上奥陶统礁滩体储集层岩性以碳酸盐岩为主, 由于储集空间的多样性及复杂性, 给利用测井资料评价碳酸盐岩储集层带来了一系列难题。以测井资料为基础, 结合岩心、实验、试油等资料, 划分出储集层储集空间类型和储集层类型。并分别建立不同类型储集层在各种测井的响应特征及响应模型, 计算出每种类型储集层的孔隙参数, 判断储集层的有效性, 识别含流体性质、并定量计算含烃饱和度, 从而实现对储集层的表征与定量评价。应用这些技术, 测井解释符合率由最初的65%提高到90%以上, 多口老井经过重新解释后获得高产油气流, 所计算的储集层参数为该区上交亿吨储量做出了重要贡献。

Abstract: The lithology of reef flat reservoir of Upper Ordovician in Tazhong No.1 slope break is dominated by carbonate rocks with variety and complexity of spaces of reservoir, which brings about difficult evaluations of it using well log data. This paper presents the space type and the reservoir type by means of log data integrated with core, experiment and well test information, including corresponding response characteristics and response models to calculate the pore parameter, fluid property and hydrocarbon saturation of each type of reservoir, thus realizing characterization and quantitative evaluation of such reservoirs. With these techniques, the coincidence rate of well log interpretation is improved from 65% to over 90% , and many old wells have acquired high production by reinterpretation. The recalculated parameters of reservoirs allow this area to add additional hundred-million-ton reserves.

Key words: Tarim basin, reef flat reservoir, carbonate rock, well log response, reservoir type, classification
