is designed for rocks bulk density estimation in section of engineering geological coal wells with a depth up to 1 000 m and hole diameters ranging from 42 to 200 mm.

 

Description

The apparatus is adapted to Russian digital log recorders such as GEKTOR, VULCAN, KEDR, etc.

Features and Advantages

• scattered gamma-ray measurements are conducted at two different distances from source;
• during measurements the sonde is forced against the well side by the surface control clamping system;
• wide range of measured density;
• drilling mud and clay coating doesn’t effect instrument readings;
• open-hole investigation;
• dry and all type of mud system investigation.
