Description
Technical field
It the utility model is related to oil and gas well drilling apparatus field, more particularly to a kind of drilling speed device.
Background technology
As the increasingly increase of oil-gas field development difficulty and the fast development of drilling technology, oil gas field want drilling speed
Ask growing day by day, be particularly deep-well, ultradeep well, quantity is or not complicated casing programme well (extended reach well, horizontal well, multilateral well etc.)
Disconnected increase, in drilling process, with the increase of drilling well well depth, not only drilling pressure aggravates shaft bottom chip hold down effect, but also bottom
The corresponding increase such as the layer intensity of rock itself, vertical crustal stress, horizontal crustal stress, seat rock drillability are deteriorated, and cause machinery
Rotating speed reduces, and not only have impact on the control of wellbore quality, but also seriously affect the drilling period and drilling cost of full well.
Drilling practice shows, in rock break-off process is crept into, since drill bit linear velocity is big, broken rock speed is high, friction mill

Include shell body, power assembly, Hooks coupling universal coupling, central shaft, speed change commutation input assembly, speed change commutation conversion assembly, change quick change
To output assembly and two level drill bit, level-one bit adapter.The device is installed on bottom hole assemblies lower part, utilizes first order bradawl
The characteristics of head broken rock speed is high drills out a small size and leads eye, since rock part stress has discharged, so as to reduce second
Level large-size drill bit broken rock difficulty, is improved wellbore entirety rate of penetration, and be conducive to direction of deflection and stick-slip is shaken
Dynamic control, for improving deep-well, ultra-deep well drilling speed, extending drill string and drilling life of bit has important actual meaning
Justice.Meanwhile the double rotating speed drilling rigs of twin-stage also have the advantages that it is simple in structure, easy to operate, be easily installed, be safe and reliable.
Above-mentioned drilling rig is realized the direction transformation of level-one drill bit and two level drill bit, the rotating speed of level-one drill bit by bevel gear set
Determined by the rotating speed of two level drill bit, internal level-one drill speed is not improved, therefore the drilling rig is to drilling speed
Effect it is limited.
