Description
Technical field
The invention belongs to drilling technology field, it is related to a kind of oscilator system and its sports immunology method.
Background technique
During drilling completion, the quality of the solid casing of cement injection will directly affect the as received basis of complete well rear sleeve
Amount.If cementing concrete is unevenly distributed leakiness, it will result in sleeve stress and be unevenly prone to breakage.Therefore, it is perfused
How cement reaches uniformly densely effect, is always well completion work person's concern.For this purpose, people devise different vibrations
It swings in device tripping in casing, evoking set tube vibration to scheme to impact casing by the swing of oscillator promotes cement wave outside casing
It is dynamic, reach cementing concrete and is evenly distributed dense effect.But theory analysis verifying support is lacked to this, data is rare.Attempt herein
By carrying out sunykatuib analysis, Exploring Analysis vibration to movement of the oscillator in straight well casing and to the main behavior of the effect of casing
Device is swung to the evaluation scheme of the solid effect of casing cement.
Summary of the invention
The purpose of the present invention is to provide a kind of oscilator system and its sports immunology methods.The beneficial effects of the invention are as follows
By construction oscillator and its motion mode is described, reason is established to the solid effect of casing cement to explore assessment oscillator
By basis.
The technical scheme adopted by the invention is that oscillator is by the first halter, the second halter, halter connector sleeve, instrument

Detailed description of the invention
Fig. 1 is oscillator structure schematic diagram of the present invention.
Specific embodiment
The present invention is described in detail With reference to embodiment.
As shown in Figure 1, oscillator by the first halter 1, the second halter 2, halter connector sleeve 3, instrument top connection 4,
The outer tube of the motor 5, motor stator 6, rotor 7, motor shaft 8, motor bearings 9, double pin ends 10, connecting bushing 11, eccentric shaft
Housing 12, eccentric shaft 13, capacity eccentric bearing 14, end-fitting 15, plug 16 form.Well head hitch point O is considered as hingedly.It is distributed structure
Prejudice Fig. 1.First halter 1 connects well head hitch point O by connecting rod, and motor drives eccentric shaft 13 to rotate, produces oscillator
Raw concussion.
Coordinate system
In order to describe motor behavior of the oscillator in casing and mud, regards O at oscillator suspension and connected as flexural pivot, with this
For origin, following coordinate system is established：
Quiet coordinate system：Oxyz：Toward the north, for y towards east, z is downward by x.Its unit forward direction vector is respectively i, j, k (Fig. 1).
Moving coordinate system：Ox1y1z1：z1Axis along oscillator is downward, x1、y1At the O in oscillator cross section, x1It is total with x
Vertical guide, y1By j1=k1×i1It determines.The unit forward direction vector of three axis is respectively i1、j1、k1。
