Wireline Double Core Barrel Q Series Head Assembly And Overshot Assembly

 

Specifications:

 

1. high quality alloy tube
2. thru-wall heat treated tube body
3. consistent concentricity, straightness
4. tapered threads

 

Core barrel introdution:

 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.

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.
