Drill bits are the most widely used in oil drilling and geological drilling. Tricone bits have the effect of rocking, crushing and shearing the formation rock during rotation. Therefore, the roller cone bit can adapt to various soft, medium and hard formations. Especially after the emergence of jet-type roller bits and long-nozzle roller cone bits, the roller bit drilling speed is greatly increased, which is a major revolution in the development of roller cone bits. Tricone bit by tooth type can be divided into milling teeth (steel teeth) roller bit, insert the tooth (carbide roller gear set) roller bit; according to the number of roller can be divided into single cone, double cone , Tricone and multi-roller bit. The most widely used at home and abroad, the most common is the tricone bit.

Rock drill bits are an essential part of the oil, exploration and drilling industries, but roller cone bits are too expensive for some drilling industries, prompting some drilling industries to produce large second-hand roller cone bits Interest, its low price and reliable quality (only 1/3 of its lifespan is used in oil drilling) reduce the cost of the drilling industry so that used roller bits have become an important part of some of the drilling industry.


Description


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.
ROLLER BEARING
Based on the calculating of the load distribution on the bearing components,all shareate bits incorporate bearings that have optimal geometry and load distribution designed to give maximum bearing life.

1.Non-Sealed Bearings

Bearing Type:Roller-Ball-Roller-Thrust Button without seal.

2.Sealed Bearings

Bearing Type:O-Ring Seal-Roller-Ball-Roller-Thrust Button. See

·The seal keeps the mud,cuttings,air and water ouside the bearings.

·The bearing works in lubricant and friction conditions,this results in less bearing wear and longer bearing life.


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.

Cautions


·Please select the applicable formation and parameters according to the instructions.


·Carefully check the bits appearance and to check the bits threaded end face,whether the serial number on the box and certificate.


·Selection of WOB and RPM should be within the limits of the recommended parameters, higher WOB and RPM cannot be used simultaneously.


·Bottom hole must be clean and bit must not be used for long section reaming.


·Drilling process must operate smoothly, find that there is Bie jump on abnormal phenomenon, should be timely analysis and take effective measures


·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.
