Description:
Yaheng's core barrel include wireline(Q series),NWG,T series and Chinese Standard core barrels.We also provide core barrel parts like core lifters,core lifter cases and locking couplings.This kind of core drill strictly complies with the international standards.Core drilling tools can lift core from drill rods.During this process,picking up coring system is not necessary.Core barrel assembly,over assembly,drill rods,holding dog,hoisting plug,circle wrench are all belong to drill tools.

Wire-line core drilling equipment is very commonly used for mineral exploration for deep holes because of practical usage.

Yaheng's products are manufactured by using high quality raw materials and designed according to DCDMA ,wire-line –Q standard.  
We offers to clients following models of wire-line core barrel compatible with -Q Wire-line Standard Drilling Equipment;
Wire-line Double Tube Core Barrel; B, N, H, P sizes;
Wire-line Triple Tube Core Barrel; B-3, N-3, H-3, P-3 sizes;
Wire-line Core Barrel T2-76, T2-86, T2-101… T series;

Wire line 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.

Wire-line core drilling tools can lift core from drill rods without picking up coring system.A complete set of wire-line drill tools include:Core barrel assembly, overshot assembly, drill rods, holding dog, hoisting plug, circle wrench etc.It has some advantages such as high penetration rate, high core recovery ratio, long bit life and lower labour intensity.The advantages can get more clear with the increasing of drill hole depth.

Application:
Used in loose, broken stratigraphic or coal extraction and protect rock (mine) heart of drilling tools.

Double core tube and tube has outer pipe, rinses through joint between the internal and external tube water flow to the bottom of the hole, protecting cores from rinses washouts. Double core tube has double motion and single movement two kinds. Double motion and core tube is internal and external core tube following bit and drill stem rotation, it in no serious loose or broken strata.

Single movement double core tube internal and external tube has bearing isolation, pipe outer pipe driven only pick up bit rotation, and broken rock tube does not rotate, avoid to core friction, vibration, etc., with mechanical damage, so it in serious loose fractured formations.these, can be well protected cores.

Use double deck core tube take core, bits need to use wall thickness of the alloy drill or diamond bits.

Due to the rock drill contact surface area increased and the lip use double deck core tube than ordinary core tube drilling efficiency to reduce. In the ledge, coal, in order to guarantee rock (mineral) heart take rate, rules must be use double deck core tube coring. More complex double core tube, except to finish single movement, in addition, aluminum, steel tube placed plastic or qualitative buckled half close tube, have a better protection of the core role.

Double core tube card broken cores and seal block within the next port, the core tube by the drill is placed in the core card fault device (fern, card spring, claw reed, etc.) to finish.
