Description
One, technical field
The present invention relates to the corollary apparatus in a kind of oil, the natural gas deep formation rotary percussion drill by driving well operations,, specifically be a kind of mechanical type down-hole absorbing percussion drilling tool.
Two, background technology
At present, in oil, natural gas deep formation rotary percussion drill by driving well operations, when adding the impact force of a high frequency, low ballistic work on drill bit top, can improve the operating efficiency and the broken rock rate of penetration of drill bit greatly.The rotary percussion drilling technology just is based on a kind of emerging drilling technology that this theory forms, and research shows that with the The field result drilling well of spinning has the high advantage of hard formation rate of penetration.But, the drill teeth problem with fracture failure that occurs easily wearing and tearing in the drilling process that spins, the vibration of analyzing extensional vibration that its reason possibly be a drill string and impactor produces due to the acting in conjunction of resonating with the extensional vibration of drill string.According to new theory; It is long and can guarantee the novel impactor of drillng operation safety to design the life-span, to improve the rotary percussion drilling operating efficiency, shorten the deep formation drillng operation cycle, the cost that reduces in the oil and gas development process is extremely important.
Three, summary of the invention
The object of the invention is exactly the defective that exists to prior art, provides a kind of and can either reduce method of longitudinal vibration of drilling string, and protection down-hole equipment safety can provide high frequency again, hang down the mechanical type down-hole absorbing percussion drilling tool of the impact force of ballistic work.
Its technical scheme is: comprise splined mandrel, spline tube, vibration damping back-moving spring urceolus, impact the assembly urceolus; The splined mandrel top is connected with top and cooperates joint, and spline tube and vibration damping back-moving spring urceolus, impact assembly urceolus join together, and splined mandrel is positioned at spline tube, vibration damping back-moving spring urceolus and impacts the assembly urceolus inner; Be provided with spring positioning joint and vibration damping back-moving spring in the vibration damping back-moving spring urceolus; Between the shoulder of vibration damping back-moving spring and splined mandrel bottom and the spring positioning joint, the splined mandrel lower end connects flow dividing structure, and splined mandrel connects plunger through flow dividing structure; The plunger outer wall is provided with the impact energy accumulation spring; The impact energy accumulation spring is between the upper end of shoulder that impacts the assembly outer tube inner wall and impact tube, and the plunger lower end is provided with water intaking valve, and it is inner that the lower end of plunger is positioned at the impact tube; The bottom of impacting tube is positioned to hold hits inside configuration; Hold and hit structure lower end connection bottom cooperation joint, it is inner that the bottom cooperates the upper end of joint to be positioned at impact assembly urceolus, and impact assembly urceolus lower end is provided with position limiting structure.
Basic principle is: drive plunger during method of longitudinal vibration of drilling string with respect to impacting the chamber and produce axially reciprocating, control the percussion that realizes impacting tube through the pressure that impacts drilling fluid in the chamber.Simultaneously,, and instrument is resetted, utilize to impact the portion of energy that assembly transforms vibration and be ballistic work, realize stablizing on the basis of drilling rod and drill bit and realize rotary percussion drilling through the energy of vibration damping back-moving spring absorbed oscillation.
Effect of the present invention is: the present invention impacts drill stem vibration damping to combine with drill bit high frequency, low ballistic work; With causing that easily extensional vibration that drill string fatigue destroys is converted into the interior ability of vibration damping back-moving spring and helps improving the ballistic work of drilling speed; Realize rotary percussion drilling; Improve efficiency of breaking rock, become harmful into favourable.Simultaneously, need not change bottom hole assemblies, not influence normal drill-in fluid circulation and creep into operation.Even instrument breaks down, still can use as damper.This instrument relatively simple for structure, principle also is feasible, each parts has enough big size and intensity in limited space, down-hole, thereby guarantees that its working life satisfies the needs of engineering.
