Product Description
Product Description:
Wireline core barrels are used when coring to greater depths, mainly because they eliminate the need to couple and uncouple the rod string each time the core is retrieved. An overshot device is dropped on a cable and directly couples onto the inner tube assembly, allowing fast retrieval of the core after each core run. Available in DCDMA sizes B, N, H. and P.
Three types of core barrels we ofered: single tube core barrels, double tube core barrels, triple tube core barrels. And lenth is available in 1.5 meters and 3.0 meters. The whole complete core barrel is made up of many spare parts, they are head assembly, pump-out adaptor, piston plug, O ring, core ejection piston, split tube, inner tube, extension tube, stop ring, core lifter, core lifter case, locking coupling, adaptor coupling, landing ring, outer tube, inner tube stabilizer, thread protector. Core bit and Reaming shell are not supplied in the core barrel and need to be ordered separately, Many geological survey and companies involved in mining exploration works use this type of equipment.
Advantages:
Faster coring at greater depths
Good stability due to constant diameter of the drill string
Excellent hydraulics
Good core recovery
