摘要

新型阵列介电测井ADT测井工具是在单频电磁波传播测井EPT仪器的基础上,采用了多级补偿推靠极板设计和多频交叉偶极子测量模式,有效地消除了井眼、泥饼等环境因素影响,通过在中国南海某油田的应用案例分析,指出了此工具在识别地层稠油、薄层,计算残余油饱和度、含水体积等方面有较好的应用效果。

Abstract

On the basis of previous dielectric equipment EPT, namely a single frequency electromagnetic wave propagation logging tool, the new type array dielectric tool (ADT) is designed with multi-level compensational electric pad and multi-frequency of cross dipole logging mode, which can eradicate effectively ambient effects, such as borehole and mud cake etc. Through analyzing the application case in oilfield of South China Sea, it is concluded that the application effects of this new tool are very good in identifying viscosity oil bearing layers, thin beds, calculation of residue oil saturation and water content.
