Hilong Efficient Cuttings Bed Clean Drill Tool

Product Introduction 

Hilong Efficient Cuttings Bed Clean Drill Tool (HLECDT™) is proprietary product which designed specifically to improve hole-cleaning performance in horizontal or complex non-conventional wells. It includes Hilong Efficient Cutting Bed Clean Drill Pipe (HLECDP™) and Hilong Efficient Cutting Bed Clean Heavy Weight Drill Pipe (HLECHWDP™). The upsets on their tube bodies have specially designed grooves. In these grooved sections the combination of rotational speed, flow rate and specially designed angles produce a number of mechanical and hydrodynamic effects that significantly improve hole-cleaning performance and greatly reduce the amount of non-productive time associated with a build-up of cuttings.

Product Advantage
