塔中地区碳酸盐岩储集层测井评价

采用井壁成像测井、方位电阻率测井和偶极声波测井等新技术，引进Ｅｌａｎｐｌｕｓ测井评价系统，对塔里木盆地塔中地区碳酸盐岩储集层进行评价。在岩心观察的基础上，对主要储集层类型及其有效性进行了测井分析，讨论了沉积相、微相对储集层的控制作用，确定了有效裂缝展布与区域断裂构造之间的关系。应用Ｅｌａｎｐｌｕｓ测井评价系统，利用试油井段测井数据，作出总孔隙度与裂缝孔隙度交会图、总孔隙度与深电阻率交会图、裂缝孔隙度与深电阻率交会图，确定各类产能储集层的总孔隙度、裂缝孔隙度及电阻率的下限值，并以此对储集层进行分类。研究成果运用于生产实践，效果良好

Carbonate reservoir logging evaluation for Tazhong field.

FMI (Fullbore Formation Microimage), ARI (Azimuth Resistivity Image) and DSI (Dualpole Source Sonic Image) are adopted to help the research work. The types of reservoir space, quantitative characteristics of fissure and cavity, reservoir effectiveness and permeability and the relation between the effective fissure's orientation and major fault's orientation are determined through analysis of logging data based on core examination. It's also discussed the effect of sedimentary microfacies controlling the reservoir. From logging data both total porosity and fissure porosity are deduces and cross plotting techniques is applied to classify carbonate reservoir and to determine the threshold of each kind of reservoir by production test data
