  2 The feature

 

 1) tooth shorter ,the space is dense, the tooth surface, the back cone hard surface strengthening ,solid carbide strengthening gage .

  2) O-ring sealed ,sliding bearing ,balls lock the cone.

 3)Palms bearing surface strengthening, improve wear resistance ,silver plated in cone, anti bite    well

 

  4)Using the pressure compensating oil controlled differential pressure seal system, more reliable sealing and lubrication.

 

 5)A new bit lubrication using resistant to high temperature of 250℃ .

Instructions for use:

1,According to the stratigraphic lithologic data, hydraulic and drilling parameters, choose the type of drill bit.

2,According to the hydraulic parameters, choose corresponding nozzle .nozzle hole size difference should not be too large, so as to avoid erosion channel.

3,Before drill down, check the drill bit size, type size is consistent with the well, the nozzle is installed, connected with the drill bit screw thread specification and the joint compliance.

4,The drill bit should be under well as the operation rules.bit and bottom contact, It must operate 30 minutes under light pressure and slow turning (drilling pressure 5-15kN, speed 60r/min) , then can be gradually increased to the normal drilling pressure.

Attentions:

1,Do not use the maximum WOB and maximum RPM at same time!

2,The bottom must be clean, various types of drill do not reaming, slow decentralization, prohibited the pier drilling.

 

3,Drilling operation must be stable, if have abnormal phenomenon ,such as bit bouncing ,should be timely analysis and take effective measures.

 

 

 

Company Information

 

The advantage of Hengji company:

1, Professional team,rich experience and advanced equipments.
2, Candesign and manufacture different types drill bits according to the customersspecial requirements.

3,processional quality control in the productive process and final product.

Introduction about rock drill bit:

1,Include single rock bit,tricone rock bit and assemble rock bit. And steel tooth rock bit,insert rock bit.

2,Rock bit is the most widely used, Cone bit work cutting teeth alternating contact the bottom of the well, the rock breaking torque is small, contacting area is small, high specific pressure, easy to eat into the stratum; the total length of working edge is big, so relatively reduce wear. Cone bit can adapt to a variety of formation from soft to hard

formations.

 3,Preparation before drilling:

1)Inspect previous bit for body damage,lost cutters or inserts,etc.Make sure no hard objects exist in bottomhole such as teeth,tungsten carbide and steel pieces clean the bottom if necessary.

2)Handle the bit with care.Place the bit on wooden pad or rubber mat.

3)Check the cutting elements for damage ,inside of bit for any other thing and ensure that nozzle O-ring are in place.Install nozzles properly as the requirement.
