Product Details

Micro Spherically Focused Log

STWQ89-200D micro spherically focused logging tool adopts a pusher in order to generate a hemispherical shaped the main current distribution at 10-20 cm into the formation through current focusing, reducing the effect of mud cake on measurement results. STWQ89-200D micro-spherically focused logging tool measures formation flushing zone resistivity RXO for residual oil saturation and movable oil calculations, and measures borehole diameter for borehole correction and cementing volume calculation.

Features

1. Improved electrode board (with PEEK, anti-wear and soft electrode board as options) and mechanical pusher design, better contact with borehole wall.

2. Temperature resistance 175°C without vacuum flask.
