Geophysical Wireline Logging Cable Borehole Steel Wire Armored Cable
Steel Wire Armored Cable Borehole Logging Cable
Borehole logging cables are used to lower logging tools and sensors into boreholes to collect geophysical and geological data. The features and types of borehole logging cables can vary depending on the specific requirements of the logging operation, but here are some common ones:
Length: Borehole logging cables can be customized to different lengths depending on the depth of the borehole and the length of the logging tool string.
Strength: The cable must be strong enough to support the weight of the logging tools and sensors, as well as any stresses and strains that may be placed on it during logging operations.
Type of cable: There are several types of borehole logging cables available, including steel armored cables, plastic coated cables, and flat ribbon cables. The type of cable chosen will depend on the specific requirements of the logging operation, including the depth of the borehole and the type of sensors being used.
