Hard and abrasive formations Tricone Drill Bit 6 3/4" 732 171mm
Description
LUGAND SHIRTTAIL ENHANCEMENT
1. Conventional Shirttail DesignThis shirttail features a”terraced”design,which increases escape area and the bailing velocity and decreases cuttings regrind and wear on shirttail and shirttail lip.
Hardmetal and wear resistant carbide were applied to shirttail and shirttail lip.
2. Particular Shirttail Design
This shirttail features a”terraced”design,which increases eacape area and the bailing velocity and decreases cuttings regrind and wear on shirttail and shirttail lop.
Hardmetal was applied to shirttail lip and lug.Wear resistant catbide on shirttail lip and lug and around the”terrace”lower part of shirttail lug.
CUTTING STRUCURES
1. Tailored insert shapes and grades manufactured using state-of-the-art tungsten carbide technology for different formations having varied drillability and compressive strength,to provide an optimum match beteen inserts wear resistance and toughness.
2. By using computer simulation of the rock bteaking at the bottom of the hole,Shareat’s engineers are able to design the best inserts space to ensure the most balanced load on each insert.
3. Double rows of gage inserts For better maintaining full gage hole.
· The bit should be kept indoor with dry and well ventilated conditions at 10-33℃ and kept from sunshine and rain. Stored under such conditions, quality of bit is guaranteed for 3 years.
