12 1/4" 532 311mm Drilling stem tools Tricone drill Bits


Mining roller cone bit is the most widely used type of bit. Tricone bit work alternately cutting tooth contact bottom hole, rock breaking torque, cutting teeth and the bottom of the contact area is small, high pressure, easy to eat into the ground, work The total blade length, and thus reduce wear and tear. Tricone bit to adapt to a variety of stratum from soft to hard. According to the number of roller can be divided into a single roller cone bit, two roller bit, tricone bit and four roller bit .


According to the cutting material can be divided into steel teeth (milling teeth) and indented roller bit .Tobot drill bit as a drilling rock tools have been widely used, significant improvement in bit performance directly reduce drilling costs, especially nearly ten Annual progress is the fastest.Life and ROP two performance indicators, they ultimately determine the extent of the impact of drilling costs Drill bit penetration rate and service life is an effective way to reduce drilling costs, it is documented that the improvement of the drilling rate The improvement of drill life is more significant than the improvement of drill life, in which the improvement of drill cutting structure is the most direct way to increase the penetration rate of drill bit.For a long time, the improvement of cutting structure has been mainly focused on the main cutting tooth


For example, in the case of cemented carbide tooth structures, wedge teeth, scalloped teeth, scalloped teeth, worn teeth, etc. have been invented successively, and in the recent decade, it has been gradually realized that the gage structure also has the effect on a drill bit drill Speed ​​and life expectancy have a greater impact, especially in the application of high-gradient wells and horizontal wells require a reasonable diameter gage structure, a number of new gage structure has been developed and applied to the roller cone bit achieved good results.


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.
