Roller Cone Bits
W series product is non-sealed roller bearing bit. This bit is suitable for surface hole drilling for every kind of wells and upper sections with good drillability. It’s advantages including low cost and high ROP.
GA series bit adopts rubber seal with roller bearing, which is the ideal and economical tool for drilling applications where middle to low WOB and high RPM are required.
GJ series bit adopts metal seal with roller bearing, which can drill stably with middle to low WOB and middle to high RPM, it’s the ideal choice for higher part of well section. Insert bit can adopt carbide compacts with high efficiency such as offset crested scoop chisel compact, scoop chisel compact, wedge compact and conical compact etc.. Increase thickness of hardfacing layer and exposure height of tooth for steel tooth bit.
This kind of series bit has several optional features, which can enhance the ability of applying for different drilling process and various complex formations.
HA series bit adopts rubber seal with journal bearing, which can sustain higher WOB under normal rotary speed and is suitable for drilling in formations from very soft to middle hard by properly selecting different cutting structure.
HJ series bit adopts metal seal with journal bearing, which can drill stably with high rotary speed, it’s the ideal tool for drilling directional well and horizontal well. Compared with conventional rubber sealed bit, its service life can be increased by 35% with same drilling parameters.
Petroleum exploration has been developed to deep formations gradually, in deep formations (compact plastic mudstone, lava and granite etc.), low ROP restrict the economic of development in deep well or super-deep well. Failure types, such as tooth break, tooth wear, cone tip wear and bit diameter shrink etc., usually appear when conventional cone bits drill in hard formations. So we have developed HF series bit for hard formations through analyze and research these failure types deeply and make use of advanced computer 3D simulation technology and lots of platform experiments.
Result in site shows HF series bit has the advantages of long service life, high reliability, fast ROP and strong guage protection ability. HF series bit is the ideal choice for drilling in hard formations and strong abrasive formations effectively and safely.
Horizontal well drilling technology is improved continuously, in which extended reach well drilling technology and multilateral well drilling technology have been developed rapidly. Kingdream follows improvement of drilling technology tightly, and has developed new type of MD high speed motor bit suitable for directional well and horizontal well successfully.
Work of bit in directional well and horizontal well has been changed greatly compare with which in straight well, new type of MD high speed motor bit has the advantages of applying for high rotary speed, strong gage protection ability and stability, high reliability, well hydraulic effect and long service life.
MD high speed motor bit is suitable for drilling with rotary speed from 300 to 90 RPM, which is the ideal choice for directional well, horizontal well and horizontal multilateral well drilling.
Increase of drilling speed in slim hole section of lower part of deep well and super-deep well is very difficult, MiniMD cone bit for slim holes has improved service life and security of bit, and decreased round trip times, therefore, realized the purpose of increasing drilling speed and decreasing drilling cost.
MiniMD cone bit for slim holes is with the feature of MD high speed motor bit, and designed with special bearing seal structure and oil storage system, tooth material, cutting structure and formation lithology are matched reasonably to solve the problems of low efficiency and tooth break & fall while drilling in complex formations.
MiniMD cone bit for slim holes is the ideal choice for slim-hole section drilling in deep well and super-deep well.
Turbine drilling tools are used widely in Russia oilfield, bits run with super high speed, rotary speed of turbine which is matched with 11 5/8” and 81/ 2” bits reaches to 400rpm ~600rpm, therefore, service life of normal cone bits is about 10 hours usually. Kingdream has invented roller-journal compound bearing for working situation with super high rotary speed, which matches with metal seal, in order to provide bit with high bearing reliability and long life in situation of super high rotary speed.
Kingdream has also developed cutting structure and extended double nozzle hydraulic structure to be suitable for drilling with super high rotary speed. SMD super-high speed motor bit matches with turbine while be used in Russia market, the stable service life of bit can reaches to more than 30 hours in the work situation of above 400 RPM.
SMD super-high speed motor bit is recommended to work in high rotary speed from 250rpm to 600rpm, which is quite economical.
