Description
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, forms annular region in outside of sleeve, model is specified in annular region
In enclosing, note with cement or with the process that other materials fill well cementation, in well cementing process, often because cement mortar quality system
It is poor, the infiltration of Oil, Water, Gas in cement mortar condensation process, it have impact on the bonding quality and intensity of Behavior of Hardened Cement Paste.
The content of the invention
The purpose of the present invention is design pulse machine impacting type well cementation vibrator, overcomes above-mentioned problem, there is provided one
Kind novel vibrating cementing unit, set tube vibration occurs in cementing operation, during being returned on cement for this device, to cement mortar
Increase energy, make cement mortar particle preferred arrangement, ensure that cement itself is closely knit and tamps the recess on the borehole wall, reduce cement
The penetrating power of stone, the cementing contact force of rock and sleeve pipe is improved, so as to greatly improve cementing quality.
The object of the present invention is achieved like this：Body is provided with pressure ring, pressure ring connection piston locating rod, piston locating rod
Side is provided with fluid cylinder cover for seat, and piston locating rod is provided with impulse oscillation piston, impulse oscillation piston connection impact bar, impact bar two
Side is provided with return spring, and bottom is provided with first throttle set in the body, is provided with the second throat bushing in the bottom of fluid cylinder cover for seat, and second
Throat bushing shear pin is installed, the second throat bushing bottom blocks ball, first throttle set bottom by sleeve pipe connection on throat bushing
Connection impact receptacle is blue, and the blue connection throat bushing support of impact receptacle is blue.
Beneficial effect of the present invention：Practicality reasonable in design, pulse machine impacting type well cementation vibrator can control vibration to open
Begin the time, other procedures will not be influenceed because of vibration, improve device reliability；Blocking protector is designed with, can be prevented
Because cement mortar or drilling fluid be not clean and caused by block and suppress pump accident, it is ensured that construction is normal；Impact is big, propagates relatively
Far.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention.
Embodiment
The vibrator as shown in figure 1, pulse machine impacting type is cemented the well, mainly by body 1, pressure ring 2, piston locating rod 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 9, the second throat bushing
10th, ball 11, impact receptacle indigo plant 12 and throat bushing support indigo plant 13 is blocked to form；Body 1 is provided with pressure ring 2, and pressure ring 2 connects piston positioning
Bar 3, the side of piston locating rod 3 are provided with fluid cylinder cover for seat 4, and piston locating rod 3 is provided with impulse oscillation piston 5, impulse oscillation piston 5
Impact bar 7 is connected, the both sides of impact bar 7 are provided with return spring 6, first throttle set 8 are provided with the middle and lower part of body 1, in fluid cylinder cover for seat 4
Bottom be provided with the second throat bushing 10, throat bushing shear pin 9 is installed on the second throat bushing 10, the bottom of the second throat bushing 10 leads to
Cross sleeve pipe connection and block ball 11, first throttle covers 8 bottoms connection impact receptacle indigo plant 12, and it is blue that impact receptacle indigo plant 12 connects throat bushing support
13。
The technological process of the present invention：
Pulse machine impacting type well cementation vibrator both ends are respectively equipped with the pin and box sub of interconnection, are installed on bunch tube and float
The upper position of hoop, the device top are joined directly together with sleeve pipe, with casing string G.I.H, under it is complete enter sleeve pipe Posterior circle drilling well
Liquid, ball 11 will be blocked before cementing and is put into sleeve pipe, starts to carry out cementing job by design；Ball reaches first throttle set 8
When, lower is blocked, liquid can only flow out through top throttle orifice, make throttle orifice is inside and outside to form pressure difference, impulse oscillation piston 5
Downward jerky motion impact receptacle indigo plant 12, vibrates sleeve pipe, while liquid inside and outside throttle orifice is passed through impulse oscillation
The intercommunicating pore of piston 5 is connected, pressure differential collapses, and impulse oscillation piston 5 return, communicating passage under the effect of return spring 6 are cut off, and are saved
Discharge orifice is inside and outside to form pressure difference again, the downward jerky motion impact receptacle indigo plant 12 again of impulse oscillation piston 5, and so on hits
Impact receptacle indigo plant 12 makes body 1 that continuous shaking occur, if having special circumstances blocking throttle orifice, set overpressure rise, and throttling
Set shear pin 9 is cut, and first throttle set 8 falls into throat bushing support indigo plant 13, re-forms passage, keeps fluid normal circulation.
