Description
Technical field
The present invention relates to improve Oil/gas Well PDC drill bit bit speed and well matter during oil, natural gas exploration and development
The underground auxiliary speed-raising instrument of amount, in particular to a kind of circumference to vibratory tool.
Background technology
In recent years, in oil, natural gas exploration and development field, as the ratio of deep-well and ultradeep well is continuously increased, due to
Deep formation formation hardness and plasticity increase, and cause that rock bit bit speed is low, drilling period is long.Bored to improve bit run
Speed, PDC drill bit is used widely.But stick slip vibration phenomenon occurs in deep formation PDC drill bit drilling process, serious restriction
PDC drill bit rate of penetration is further lifted, extreme influence its service life.Theoretical research and field practice show, if in PDC
On drill bit it is extra apply a high frequency, by a narrow margin circumference vibrated to (unidirectional or two-way), can significantly reduce or eliminate PDC drill bit
This stick slip vibration phenomenon, greatly improves bit speed and bit life.
Developed both at home and abroad at present it is various can produce high frequency, circumference is to vibratory tool by a narrow margin.These vibratory tools from
On power end structure, turbine or screw drive can be divided into and cleaner for high-pressure drilling fluid directly drives two big types.
The turbine drives type instrument that patent US6742609B2 is given and the screw rod driven instrument that CN101463709A is given
Cause that its entire length size big, complex structure, consumable accessory are more Deng the presence due to turbine or screw rod, reliability is low；Patent
The cleaner for high-pressure drilling fluid that CN102454364A, CN203430420U, CN103628819A and CN104963624A etc. are given directly drives
Ejector half instrument, is related to matching problem while coaxial multiple metallic sealing section in its structure, exist operation element abrasion it is very fast,
The problems such as part sealing surface easily fails.
The instrument that above-mentioned patent document is given lacks PDC drill bit and carries brill braking function.I.e. in PDC drill bit lift-off shaft bottom
When afterwards, in off working state, if keep circulation of drilling fluid, instrument still sustained vibration, can so greatly increase instrument due to
Vibration causes the risk for releasing or even dropping.
