Through Casing Formation Resistivity Logging Tool

Brief Introduction:

Through Casing Formation Resistivity Logging Tool is used to measure the formation resistivity in cased wells.

Determine the saturation parameter of reservoirs in cased wells and evaluate the water-flooded degree of remaining.

Provide a technical basis for fracturing, profile control and water plugging, and check flooding effects of oilfields.

The radial detection depth is up to 2-11m, and the product applies to any fluid and any porosity conditions.

The measuring error is less than ±7% within the range of 1Ω.m~100Ω.m.

No.
