Description
Technical field
Completion tool field is the utility model is related to, the work of well cementation effect is improved in particularly a kind of vibration cementing operation
Tool.
Background technology
Vibration cementing technology is to be drilled an emerging technology in well field, and common vibration cementing instrument mainly has turbine type
Hydraulic vibration instrument, turnover plate type vibratory tool and pipe internal vibration instrument etc. are several；But it is limited by implement power, the actual feelings in underground
The factors such as the decay of condition, tubing string eigentone and vibration, vibration is after certain distance is propagated caused by vibration cementing instrument
Energy attenuation is very fast, and therefore, it is limited that well cementation effect is improved in the place that vibration cementing instrument is adjusted the distance farther out.At present, hydraulic vibration
Cementing tool can only be arranged in bottom hole location, can not be placed in the middle part of pipe string, because there is a large amount of mechanical structures inside it, be arranged in
Construction in later period operation can not be then carried out in the middle part of pipe string.Pipe internal vibration cementing tool can realize the vibration of full well section, but it needs
The tripping in out of pipe after cementing operation terminates, at this moment cement comes into a few hours in Hou Ning stages, and this instrument is not
Vibration, therefore this vibration cementing instrument can be applied to cement mortar influenceing most important injection and replacement stage on cementing quality
Lifting effect to cementing quality is smaller.
The content of the invention
The purpose of this utility model is to be directed to the problem of effective vibration length existing for the existing vibration cementing work of mesh is limited, if
A kind of vibrations scope that can effectively expand vibration cementing instrument has been counted, has strengthened body vibration effect, so as to lift cementing quality
Vibration cementing with resonance pipe nipple instrument.
The technical solution of the utility model is：
A kind of vibration cementing resonance pipe nipple instrument, including base tube, outer layer sealing shroud and resonant structure, wherein：The base
Pipe both ends carry connector, and base tube stage casing is provided with annular groove, set raised ridge vertically on annular groove, on ridge between
Every multiple necks are distributed with；The resonant structure forms openning shape garden ring structure by the vibrating mass at both ends by middle linkage section,
The middle linkage section of multiple resonant structures is engaged by clamping with the neck on base tube ridge respectively；The sealing of outer layer sealing shroud is socketed in base
Annular groove outside pipe, and keep in the annular groove of each resonant structure after sealing in addition to being connected with ridge neck, no
It is in contact with base tube, outer layer sealing shroud.
Such scheme also includes：
The resonant structure has the structure of same resonance frequency, and its vibrating mass includes U-shaped tuning fork structure, V-arrangement tuning fork knot
Structure or concave, convex shape tuning fork structure.
Annular groove outside base tube is sealed and fixed by outer layer sealing shroud by seal and fixing pin.
The utility model has the advantage of：The purpose of design of resonance pipe nipple is to re-use, distribute vibrational energy, subtract
Few meaningless loss of the vibrational energy in transmission, more vibrational energies are applied in vibration cement mortar, improve vibration wave and propagate
Distance, to improve vibration cementing effect.The reserved chamber portion of the instrument is provided with the resonance knot with vibration cementing tool matching
Structure, it can absorb, store and amplify and be vibrated caused by the vibration cementing instrument of completion tubular string bottom；Because do not have in the instrument inner tube
There is mechanical structure, tube wall does not influence later stage operation, can be arranged in the middle part of completion tubular string smoothly without raised or sunken.
This tool construction is simple, and reliability is high, and inside has prevented the generation of serious underground problem without labyrinth；This work
Tool coordinates vibration cementing instrument to be used together, but the startup and work of instrument coordinate without special processing step, construction risk
It is small.
Brief description of the drawings
Fig. 1 is a kind of vibration cementing resonance pipe nipple instrument half section structure diagram of the utility model；
Fig. 2 is that resonance pipe nipple removes outer layer sealing shroud resonant structure arrangement schematic diagram in Fig. 1；
Fig. 3 is Fig. 2 left view.
Embodiment
Structure of the present utility model is described in detail below in conjunction with the accompanying drawings.
Such as Fig. 1, the utility model is mainly by base tube 1-1, seal 1-2, fixing pin 1-3, outer layer sealing shroud 1-4, altogether
Structure of shaking 1-5, steady pin determine 1-6 and sealing structure 1-7 compositions.Wherein, described seal includes and is not limited to rubber seal
Circle, the resonant structure include and are not limited to tuning fork.
Base tube 1-1 plays a part of the upper lower tubular column of connection and setting tool part, outer layer sealing shroud 1-5 by upper lower contact
Coordinate the annular groove among base tube 1-1 to form one piece of mezzanine space, this part mezzanine space to dispose resonant structure 1-5,
And the space of resonant structure 1-5 vibrations is left, seal 1-2,1-4 are responsible for sealing mezzanine space, prevent well liquid from entering
Enter mezzanine space, to reduce resistance during resonant structure 1-5 resonance, steady pin determines 1-3,1-6 and is responsible for consolidating for outer layer sealing shroud 1-4
It is fixed, ensure the integrality and safety of tripping in process tool.
Such as Fig. 2, the mezzanine space for the pipe nipple that resonates can arrange several resonant structure 1-5, and each resonant structure is by both ends
Vibrating mass 2-1 forms openning shape garden ring structure by middle linkage section.Vibrating mass 2-1 includes U-shaped tuning fork structure, V-arrangement tuning fork knot
Structure or concave, convex shape tuning fork structure.
Such as Fig. 3, resonant structure is linked together by the raised ridge of middle linkage section and base tube.
These resonant structures are arranged in mezzanine space, can ensure that mezzanine space is not outside by sealing structure sealing
Fluid invades, so that interlayer cavity is maintained at cavity state, can so ensure that resonant structure is easier excited vibration, also may be used
To reduce energy attenuation of the resonant structure after excited vibration.The intrinsic frequency of resonant structure in resonance pipe nipple is with being placed in
The working frequency of the vibration cementing instrument of well casing string bottom is consistent, while should be close proximity to the intrinsic frequency of sleeve pipe.Work as vibration
After cementing tool is started working, the excitation of completion tubular column cementing tool vibrated starts with vibration, when vibration is transferred to altogether
Shake pipe nipple when, the resonant structure to resonate in pipe nipple mezzanine space will progressively absorb vibrational energy and resonate, over time
Increase, the amplitude of resonant structure can gradually increase, and vibration is amplified into follow-up resume and passed, the resonance pipe nipple on top will repeat this
Process, until vibrational energy exhausts in communication process, by this process, resonance pipe nipple, which can be realized, improves vibration cementing effect
Fruit and the effect of oscillating region.
Vibrational energy mainly has following whereabouts caused by vibration cementing instrument：It is transferred in cement mortar around and drives it
Vibration, it is transferred to completion tubular column and drives its vibration and small part to overcome resistance to be converted into heat energy；It is to shake to drive cement mortar vibration
The main purpose of dynamic well cementation, this partial vibration energy can improve cement slurry property, improve well cementation effect；And resistance is overcome to produce
Heat energy be useless, there is no obvious effect to the performance improvement of cement mortar, be in vibration cementing vibrational energy lose part,
But this partial loss energy very little, can be ignored.
