Lithodensity gamma-gamma logging tool GGKLP-76
Designed to measure rocks bulk density and determine rocks photoelectric absorption index.
Used for logging of open oil and gas holes filled with any mud; the tool operates with a three-conductor carrying logging cable up to 7000m long and log recorders that provide for command transfer and data receipt in “Manchester-2” code.
Active tasks:
- measure rocks bulk density and determine rocks photoelectric absorption index;
- detailed lithological identification and stratigraphic studies;
- оreservoir properties identification and rocks mineral composition identification.
