Description

Pulse machine impacting type well cementation vibrator
Technical field
The present invention relates to technical field of oil extraction equipment, especially pulse machine impacting type well cementation vibrator。
Background technology
After drilling, bore diameter is more than casing diameter, annular region is formed in outside of sleeve, within the scope of annular region appointment, note with cement or with the process of other material filling cry cement the well, in well cementing process, often because of cement mortar quality system poor, the infiltration of Oil, Water, Gas in cement mortar condensation process, have impact on the bonding quality of Behavior of Hardened Cement Paste and intensity。
Summary of the invention
It is an object of the invention to design pulse machine impacting type well cementation vibrator, overcome above-mentioned Problems existing, thering is provided a kind of novel vibrating cementing unit, this device, when cementing operation, can return on cement and set tube vibration occurs in process, energy is increased to cement mortar, make cement mortar granule preferred arrangement, it is ensured that cement self is closely knit and tamps the recess on the borehole wall, reduces the penetrating power of Behavior of Hardened Cement Paste, improve the cementing contact force of rock and sleeve pipe, thus being greatly improved cementing quality。
The object of the present invention is achieved like this: body is provided with pressure ring, pressure ring connects piston location bar, bar side, piston location is provided with fluid cylinder cover for seat, piston location bar is provided with impulse oscillation piston, impulse oscillation piston connects impact bar, impact bar both sides are provided with return spring, bottom is provided with first throttle set in the body, it is provided with the second throat bushing in the bottom of fluid cylinder cover for seat, second throttling puts and is provided with throat bushing shear pin, second throat bushing bottom is by telescopic joint blocking ball, first throttle set bottom connects impacts receptacle indigo plant, impact receptacle indigo plant and connect throat bushing holder indigo plant。
The method have the benefit that reasonable in design is practical, the pulse machine impacting type well cementation controlled damping of the vibrator dynamic time started, other procedures will not be affected because of vibration, improve device reliability；Design has blocking preventer, can prevent the blocking that is that cause because cement mortar or drilling fluid are unclean from suppressing pump accident, it is ensured that construction is normal；Impact force is big, propagates relatively far away from。
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention。
Detailed description of the invention
As shown in Figure 1, pulse machine impacting type well cementation vibrator, is mainly made up of body 1, pressure ring 2, piston location bar 3, fluid cylinder cover for seat 4, impulse oscillation piston 5, return spring 6, impact bar 7, first throttle set 8, throat bushing shear pin the 9, second throat bushing 10, blocking ball 11, impact receptacle blue 12 and throat bushing holder indigo plant 13；Body 1 is provided with pressure ring 2, pressure ring 2 connects piston location bar 3, bar 3 side, piston location is provided with fluid cylinder cover for seat 4, piston location bar 3 is provided with impulse oscillation piston 5, impulse oscillation piston 5 connects impact bar 7, impact bar 7 both sides are provided with return spring 6, first throttle set 8 it is provided with in body 1 middle and lower part, the second throat bushing 10 it is provided with in the bottom of fluid cylinder cover for seat 4, second throat bushing 10 is provided with throat bushing shear pin 9, second throat bushing 10 bottom is by telescopic joint blocking ball 11, first throttle overlaps 8 bottoms and connects impact receptacle indigo plant 12, impact receptacle blue 12 and connect throat bushing holder indigo plant 13。
The technological process of the present invention:
Pulse machine impacting type well cementation vibrator is respectively arranged at two ends with interconnective pin and box sub, it is installed on the upper position of bunch tube float collar, this device top and sleeve pipe are joined directly together, with casing string G.I.H, under complete enter sleeve pipe Posterior circle drilling fluid, before cementing, blocking ball 11 is put in sleeve pipe, start to carry out cementing job by design；When ball arrival first throttle overlaps 8, blocking lower, liquid can only flow out through top throttle orifice, make throttle orifice inside and outside formation pressure reduction, the downward jerky motion impact receptacle indigo plant 12 of impulse oscillation piston 5, sleeve pipe is made to vibrate, make liquid inside and outside throttle orifice be connected by impulse oscillation piston 5 intercommunicating pore simultaneously, pressure differential collapses, impulse oscillation piston 5 is return under return spring 6 acts on, communicating passage is cut off, pressure reduction is formed again inside and outside throttle orifice, impulse oscillation piston 5 is downward jerky motion impact receptacle indigo plant 12 again, impact receptacle indigo plant 12 makes body 1 that continuous shaking to occur and so forth, if have special circumstances blocking throttle orifice, set overpressure raises, throat bushing shear pin 9 is cut off, first throttle set 8 falls into throat bushing holder indigo plant 13, again passage is formed, keep fluid normal circulation。
