9 7/8" 645 251mm used oil well Tricone Drill Bit
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 cone can be divided into single-cone bit, three teeth Drill bit and assembly of multi-cone bit. The most widely used at home and abroad, the most common is the tricone bit.
Description
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.
