Description
Technical field
The utility model relates to the corollary apparatus that belongs to oil, gas drilling, more particularly, relates to a kind of drilling well damping speed enhancing apparatus.
Background technology
In drilling process, the reliability of drill bit and underground tool string is the key factor that affects drilling speed, and drill bit lost efficacy or the underground tool string fault will have a strong impact on drilling process, increases drilling cost.Variation at any time along with the complicated of drilling environment and down-hole situation, guarantee lasting, the steady operation of drill bit and underground tool string, reduce drill bit and lost efficacy and the underground tool string fault rate, the raising single drilling depth efficiency that makes a trip is problem in the urgent need to address in drilling engineering.Field practice shows; damping speed-raising instrument is installed above drill bit; can effectively alleviate in drilling process the instant impact that drill bit bears; the impact of shock isolation on underground tool string; effectively protection Cutter and bearing, reduce the underground tool string fault rate, and then improve bit speed; reduce drilling cost, be applicable to the multiple drilling modes such as extended reach well, directed drilling, horizontal drilling, vertical drilling, coiled tubing drilling.
Current, the damping instrument that raises speed for domestic more existing drilling wells, be mainly magnetic coupling damper, drill-string shock absorbers, torsion spring damping in hydraulic oil damper, drill collar.Adopt the hydraulic oil damping to rely on hydraulic oil larger, once occur to leak, just lose shock-absorbing function, unstable properties; Magnetic coupling shock absorber structure complexity in drill collar, moving component easily is damaged, and safeguards loaded down with trivial details; The drill string damping, not for the shaft bottom complex situations, is not directly played the effect of protection drill bit and downhole tool; The torsion spring damping was easily lost efficacy under the Long-term Vibration situation, can't play cushioning effect.More above-mentioned shock absorbing tools are failed to stablize and are solved the impact of vibration on drill bit and downhole tool, have restricted the lifting of bit speed.
The utility model content
The technical problems to be solved in the utility model is, provides a kind of and can effectively protect Cutter and bearing, extends bit life, reduces the drilling well damping speed enhancing apparatus of the fault rate of underground tool string.
