SITAN STWQ89-200D Micro spherically focused logging tool is pad mounted and is a spherically focused micro-resistivity device designed to measure Rxo, flushed zone resistivity. SITAN STWQ89-200D micro spherically focused logging tool is used to calculate the residual oil saturation and movable oil. The borehole diameter was measured by the DC constant current source power supply mode for borehole correction and calculation of the cement volume.
Features:
1. Pad with PEEK, anti-wear and soft plate as options and mechanical push-back design, better wall attachment.
2. The temperature resistance of bare skeleton can be 175°C.
