Description
Technical field
The present invention relates to a kind of damper, specifically a kind of oil-gas mining drilling well damper.
Background technique
Existing damper is to generate damping effect by mechanical (such as folded spring) or hydraulic (such as oil cylinder) deformation.Damping
Process will cause lag in the effect of recoil strength, while this recoil effect 100% can not touch in use
DRILL-STRING SYSTEM is easy to cause failure rate to increase.
In drillng operation, the frequent bouncing of drilling tool of drill bit is caused since shaft bottom is uneven, if drill bit is directly connected to drill collar,
Entire drill string will accelerate to move up and down together with drill bit, generate strong vibration, destroy optimal drilling condition, reduce drill bit and brill
Have service life, or even damage drilling equipment.There are many method, including percussion drill, rotation, sound waves etc., according to different spudders for drilling well
Skill, landform and equipment situation, are used in different methods.However, various boring methods can all have different longitudinal directions and axial vibration
Dynamic, these vibrations can cause impact force to drill string, lead to certain component fatigue damages or even failure in drill string；Service life is short,
It damping continuous work 500 hours, needs to overhaul, reprocesses and maintenance cost is very high.
Outmoded damper has apparent defect, is easy after being worked at the same time in use due to multiple components
Heat, and be not especially to be completely suitable for various drilling methods, general rate is not high, cannot avoid well near drill bit and drill bit
Drilling tool damage.
Chinese patent（Authorization Notice No.：CN 206513317 U）A kind of oil-gas mining drilling well damper is disclosed, by more
A part composition, the damper include：Upper drive sub, cylinder, central tube, compression cam, compressing rubber, lower drive shaft,
Lower part tube socket and double female connectors, the beneficial effects of the present invention are：By compressing cam in the oil-gas mining drilling well damper
The tangent structure with the end curved surface of compressing rubber, can make damper before compression has lower rigidity, and effectively generates
Damping force；Rigidity with higher after compression, protects product itself not to be destroyed under the conditions of high pressure；After stress disappearance,
Compressing rubber can reset completely, guarantee stress and be heated evenly；And when reprocessing and safeguarding, compressing rubber is only needed to change,
Maintenance cost is reduced, is improved work efficiency, service life is extended.But the damping effect of above-mentioned apparatus is in practical application
It is unsatisfactory, there is the inconvenience of dismounting maintenance, maintenance cost is still very high, influences working efficiency and service life.
