Terracore 46 T2 conventional double tube core barrel
Geotechnical Drilling and Exploration Core Barrel Assembly Competition
Conventional Double Tube Core Barrels For Geotechnical Drilling and Exploration Core Barrel Assembly
Terracore conventional, double tube core barrel T2 is a thin-wall core barrel system for most types of homogenous or somewhat broken formations where water flush can be used.
Features & benefits:
1. Reliable tools for cost-efficient, undisturbed shallow core sampling.
2. A superior solution for site investigation in soft to hard formations.
3. Cost-effective core barrels for high productivity in shallow formations.
Specifications
1. NQ HQ PQ head assembly manufacture
2. NQ HQ PQ head assembly high quality
3. API & ISO NQ head assembly
4. On time delivery
1. Features:
When the driller wants to remove core from a conventional core drill, the entire core barrel has to be removed from the hole. This is time-consuming, as each rod has to be removed one at a time.
With wireline drilling, a barrel of core can be removed from the bottom of the hole without removing the rod string. When the driller wants to remove the core, an overshot is lowered on the end of a wireline. The overshot attaches to the back of the core barrel inner tube and the wireline is pulled back and the inner tube disengages itself from the barrel.
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.
