Downhole tool KST-GK
Appointment
The borehole tool KST-GK is designed to measure apparent resistivity (CS), spontaneous polarization (PS) potential, fluid temperature, and also to record the intensity of gamma radiation from formations along the wellbore.
Scope - research in wells drilled in water at temperatures from 0 to 60 ° C and a pressure up to 5 MPa.
Execution options
-
KST- GK-A - a borehole device KST-GK with autonomous power supply (with a channel GK), can additionally be equipped with depth control equipment;
-
KST- GK-K - downhole tool KST-GK with cable feed (with GK channel).
