Wireline Core Drill Pipe
Wireline Core Drilling is a special kind of drilling process that allows the core barrel to be removed from the base of the hole without taking out the drill rod.
Product Introduction
Wireline Core Drilling is a special kind of drilling process that allows the core barrel to be removed from the base of the hole without taking out the drill rod. And the drill rod only has to be withdrawn up to the surface when the drill bit needs to be changed. Our Wireline Core Drill Pipe can be used for medium to ultra-deep boreholes, and it can provide the most efficient core sample extraction from the rock mass without pulling the entire drill string. This drill pipe uses an API standard screw, ideal for core drilling exploration projects.
Product Features
Wireline Core Drill Pipe has a good time-saving function, for it achieves the greater depth that can be drilled before retrieving the core barrel to the surface. It has a higher penetration rate and footage due to the presence of a shock absorber. Also, the cost per meter of the drilling operation is lower with wireline coring technology than conventional methods. The reliability of wireline drilling is higher and thus the cost of maintenance is lower. Using our Wireline Core Drill Pipe can also increase the safety level of operation for it reduces less retrieving, thus achieving fewer accidents.
