JJY-3D Diameter Borehole Logging Equipment Liquid Level Water Well Logging Equipment Borehole Caliper
Features & Benefits
1,Opening and closing of the motor-driver caliper arms is by surface command, allowing the probe to run into the borehole with the arms retracted.
2,Easy exchangeable caliper arm lengths and wear tips
Applications
Rock integrity evaluation
Fracture and cavity localization
Borehole diameter measurement
Borehole volume calculation before borehole completion, cementation
Often used in the implementation of environmental correction equations for other logs
