Art
Held the invention belongs to drilling technology field, more particularly to a kind of brill deep-well with drill string for becoming twist-drill head based on double speed
Row mechanism.
Background technology
Current drilling equipment is transmitted power on the drill bit of underground frequently with power output on well by drill string.For
It is required that the depth chin-deep of institute's drilling well, it would be desirable to the drill string of extra long distance, it is spliced often through many drill strings.It is deep when boring
When well is directed drilling, well bore axis will with one or more flex points, it is difficult to ensure that drill string is operated on the center line of well bore,
This will cause the deviation of drill bit drilling well.Drill string is maintained on the center line of well bore, or only keep being connected attached with drill bit
Near drill string is necessary on well bore center line.
For drill bit, the drill bit used by current drilling well is mostly monoblock cast or forging, for different depth tool
There is a drilling well of the lithosphere of different hardness, or the harder drill bit of single use or changed in real time according to the lithosphere for being bored
Drill bit has reached the purpose of drilling well.Both of which has certain problem, more or less when softer lithosphere is bored for the former
Abrasion are generated to drill bit, spent cost with relatively soft drill bit than being bored spent by softer lithosphere during this
Cost is high, does not calculate very much;For the latter, often the raising of time cost is caused by more bit change.
