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.
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.
