Description
Technical field
The present invention is the completion equipment after oil drilling, is a kind of vibration cementing device.
Background technique
Tripping in casing is wanted after oil drilling, then cement slurry is injected out of casing, it is empty through the annular between casing and the borehole wall
It is returned on chamber, makes casing cement on the borehole wall, on the one hand prevented cave-in, on the other hand prevent inter-layer fluid from altering, it is next with benefit
Step production, this process is complete well.The well cementation thousands of rice of well section, the interval between casing and the borehole wall only have several centimetres, add water
The poor fluidity of mud, cement slurry are difficult to enrich so far-reaching narrow space.If cement slurry cannot enrich casing and the borehole wall
Between toroidal cavity, there is fixed mass problem.If there is cementing quality problem, casing is not fixed on the borehole wall, meeting
It generates lateral force and damages casing, shorten the service life of oil-water well；If there is cementing quality problem, it there is also interlayer and alter
Stream, prevents oil-water well from normally producing.
Summary of the invention
The object of the present invention is to provide a kind of vibration cementing device, overcome the problems, such as above-mentioned, cement slurry is made to enrich set
Toroidal cavity between pipe and the borehole wall improves the cementing quality of oil-water well, can normally produce after guaranteeing the complete well of oil-water well, it is ensured that grease
Well has enough service life.
The object of the present invention is achieved like this: including casing, bruising rubber plug, upper anchor tip, starter, upper overcurrent
Set, vibrator, connecting tube, lower overcurrent set, lower anchor tip, starter are mounted on the upper end of vibrator, the top of vibrator
In insertion overcurrent cover left eccentric orfice in, vibrator is installed in the lower part of upper anchor tip with upper overcurrent set, connecting tube it is upper
Portion is connect with the lower part of upper anchor tip, is limited in overcurrent set in the lower part of upper anchor tip, the left avertence of lower overcurrent set
Heart hole is sleeved on the lower part of vibrator, and the top of lower anchor tip and the lower part of connecting tube connect, and is sitting in lower overcurrent set lower solid
Determine in the inner circular bead of connector, upper anchor tip, upper overcurrent set, vibrator, connecting tube, lower overcurrent set, the assembling of lower anchor tip
Upper anchor tip is connected to the lower part of casing after integral, and bruising rubber plug is put into casing, leather cup and casing on bruising rubber plug
Inner wall contact, the pressure on bruising rubber plug be higher than under pressure when, the inner wall shape of leather cup and casing on bruising rubber plug
At one-way sealing, upper overcurrent has put on flowing hole, and lower overcurrent has put on lower flowing hole, and the liquid stream under bruising rubber plug can pass through
The upper flowing hole, connecting tube, the lower flowing hole flow downward.
The beneficial effects of the present invention are: suppressing when well cementation into casing pushes away the cement slurry being about under it under bruising rubber plug
Enter in the toroidal cavity between casing and the borehole wall, the rear bruising in place of bruising rubber plug triggers starter, makes vibrator high speed rotation
Vibration is generated, the mechanical wave that this mounting means of vibrator is generated when vibrator high speed rotation is vibrated is along casing string to distally
Transmission, the cement slurry involved between casing string and the borehole wall generate vibration, the air gap in cement slurry are escaped, and enrich cement slurry and fill out
Gap sews and mend, packed uniform distribution realizes the purpose for improving cementing quality, can normally produce after guaranteeing the complete well of oil-water well have aobvious
The economic benefit of work.
Detailed description of the invention
Attached drawing 1 is installation diagram of the invention.
Specific embodiment
1 pair of the embodiment of the present invention is illustrated with reference to the accompanying drawing.
As shown in Figure 1, the embodiment of the present invention include casing 1, bruising rubber plug 2, upper anchor tip 3, starter 4, on
Overcurrent set 5, vibrator 6, connecting tube 7, lower overcurrent cover 8, lower anchor tip 9, and starter 4 is mounted on the upper end of vibrator 6, shake
The top of dynamic device 6 is inserted into the left eccentric orfice of upper overcurrent set 5, and vibrator 6 is installed under upper anchor tip 3 with upper overcurrent set 5
In portion, the top of connecting tube 7 is connect with the lower part of upper anchor tip 3, is limited in overcurrent set 5 under upper anchor tip 3
In portion, the left eccentric orfice of lower overcurrent set 8 is sleeved on the lower part of vibrator 6, the top of lower anchor tip 9 and the lower part of connecting tube 7
Connection is sitting in lower overcurrent set 8 in the inner circular bead of lower anchor tip 9, and upper anchor tip 3, vibrator 6, connects upper overcurrent set 5
Adapter tube 7, lower overcurrent cover the lower part that upper anchor tip 3 after 8, lower anchor tip 9 is assembled integrally is connected to casing 1, bruising rubber plug 2
It puts into casing 1, the leather cup on bruising rubber plug 2 is contacted with the inner wall of casing 1, under the pressure on bruising rubber plug 2 is higher than
When pressure, the inner wall of leather cup and casing 1 on bruising rubber plug 2 forms one-way sealing, has upper flowing hole 5-1 on upper overcurrent set 5, under
There is lower flowing hole 8-1 on overcurrent set 8, the liquid stream under bruising rubber plug 2 can pass through the upper flowing hole 5-1, connecting tube 7, institute
The lower flowing hole 8-1 stated flows downward.
In the bottom of casing string under the present invention, with, in pit shaft, being squeezed on ground into casing 1 under casing after drilling well
Prepared cement slurry, cement slurry flow downward through the upper flowing hole, connecting tube, the lower flowing hole, then return upwards
After cement slurry has been beaten, bruising rubber plug 2 is put into casing 1, then is beaten into casing 1 for toroidal cavity between casing 1 and the borehole wall
Displacement fluid replaces the cement slurry in casing 1 to the toroidal cavity between casing 1 and the borehole wall, and bruising rubber plug 2 and starting fill
Vibrator 6 can be made to start to work after setting 4 contacts, the mechanical wave of generation is transmitted along casing string to distal end, involves casing string and well
Cement slurry between wall generates vibration, and the power of vibrator 6 is battery, and the electric energy of battery can guarantee the vibration of vibrator 6 about
Half an hour escapes the air gap in cement slurry when vibrator 6 shakes, and so that cement slurry is enriched joint filling and mends gap, cement slurry enriches casing 1
Toroidal cavity between the borehole wall guarantees cementing quality.
