Application of New Array Dielectric Tool ADT to Oil Fields of South China Sea

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.
