Description
Technical field
The utility model relates to the drilling tool that oil exploration drilling is used, and is in particular a kind of jet fluctuation generator and jump bit device thereof, is mainly used in the probing of hard rock stratum or deep-well, is applied to aspects such as oil exploration, geological resource exploration.
Technical background
Present stage oil gas and the method for geological prospecting drilling well be rotary drilling, meet the deep-well stratum and bore when meeting the hard rock layer when boring because the drillability of formation rock is poor, rate of penetration is lower.It is the boring method of assisting that the jet fluctuation jump bit that uses at present impacts the broken rock of crushing as the broken rock of rotational shear as master, aperiodicity ground, the periodically pulsing shock loading is provided, can improve rate of penetration, but because of easily worn part life-span weak point, and be not used widely.Its primary structure is a split combination structure, comprises impulse generator, signal transmission passage, piston mechanism and block stamp mechanism.
There is following defective in the jet fluctuation jump bit that is using at present:
1, impulse generator complex structure.Adopted split combination structure, error is bigger, and has the gap, fragile this generator when slurry jet passes the gap.In heterogeneous fluid (liquid, solid, gas), the surge pressure wave attenuation is very serious, especially in the structural fluid higher at solid concentration, that viscosity is higher, viscosity is strong, dissipation factor is bigger, surge pressure wave can't be propagated in passage, thereby also just can't act on jet, and can't make jet change runner, cause the impactor can't continuous operation;
2, the piston mechanism design is unreasonable, and there are the gap in piston mechanism and impulse generator.Slurry jet, enter piston-cylinder after, when slurry jet commutated, the part solid particle can not be discharged from along the jet fluid passage of complications, remained in the piston-cylinder, also had the part solid particle to be stuck in the gap of piston mechanism and impulse generator in addition.Facts have proved that residual solid particle takes care of the pence, accumulate in cylinder sleeve and the gap, piston can't be moved, cause impactor to work;
3, cooperating between block stamp mechanism and the piston rod is cone match, mainly relies on the pre-friction-tight between the conical surface, keeps connecting.Facts have proved: because mud enters the conical surface and played lubrication, reduced the frictional force of the conical surface, and reason such as vibration, piston rod is connected with the block stamp disengaging, cause the block stamp cisco unity malfunction.
4, in addition, slurry jet has very strong cutting, grinding and erosion ability, existing jet flow type shocker, at high-speed jet runner mouth, do not adopt wear-resistingly cut, the high rigidity carbide alloy of anti-impact erosion, perhaps do not adopt integrally-built carbide alloy member, cause fluidic and impactor life-span very short, can't satisfy the drilling well needs.
