Description
Technical field
The present invention relates to a kind of oil well casing prosthetic device, more specifically, the two-way vibration casing repairing dress of a kind of self-sealing
Put.
Background technology
It is known that in oilfield process, due to reasons such as stratum wrigglings, often making down-hole casing occur radially to become
So that caliber narrows, impact oil well normally produces shape, at present, the well that down-hole deformed casing is repaired of use on oil field
Lower power tool is mainly tube expander and milling cone repairs two kinds of techniques, and tube expander reparation drill string reinforcing in horizontal well is limited, very
Difficulty repairs original latus rectum；Milling cone is repaired to be needed to enter milling tool under classification, and major diameter milling cone radial dimension is close to sleeve pipe
Easy blocked portion during removing during internal diameter, repeatedly changes milling cone and leads to drilling labor intensity larger, more affect efficiency of construction
It is unable to the size of effective control repairing casing power, downhole tool also can be stuck in down-hole and can't pump out sometimes, be very easy to cause to make
Industry failure, produces down-hole accident, has a strong impact on production, some wells are not simply just repaiied, and have scrapped it, cause very big waste, sternly
Important place affects the normal production in each oil field, and the production in oil supply field and operation cause direct or indirect loss.
Utility model content
This application provides a kind of two-way vibration casing repairing device of self-sealing, self-sealing two-way vibration casing repairing fills
Put, including the circular roller reshaper positioned at bottom and superposed two-way bumper jar, wherein, described two-way bumper jar includes
To lower and on be linked in sequence successively self-packer, multistage hydraulic propeller, anchor group, vibration device, compression relief cock and
Pipe nipple variable buckle.
Further, described self-packer includes body, flange and sealing member.
Further, described multistage hydraulic propeller is that multiple hydraulic cylinders are combined in series in order.
Further, the outer surface of described circle roller reshaper is covered with cydariform roller.
Further, described vibration device is hydraulic super fishing jar.
The self-sealing two-way vibration casing repairing device of the application increased in original shaping technique self-packer and
The effect of two-way vibration, has slight bending and set to damage serious well to sleeve pipe, according to field experimentation result success rate 85% with
On, also once there being the situation of card in work progress, can smoothly instrument be carried by itself vibration and self-packer
Go out ground, it is to avoid construction team's large-tonnage above carries, and unsafe factor.
Brief description
By purely providing unlimited example, with reference, the further characteristic of the present invention and advantage will become apparent from,
Wherein:
Fig. 1 illustrates the perspective view of the application self-sealing two-way vibration casing repairing device；
Fig. 2 illustrates the half sectional view of the application self-sealing two-way vibration casing repairing device.
Specific embodiment
The self-sealing two-way vibration casing repairing device of the application is a kind of for repairing to oil well casing necking deformation
Combination complete set of equipments, it, by the use of hydraulic pressure as power source, produces huge motive force, undergauge is covered and repairs at damage, for same
At a bite well one or many places and continuous set damage an operating tool string and just can quickly repair, and reach former well basic size, make oil
Well quickly returns to normal production.
The self-sealing two-way vibration casing repairing device of the application, including the circular roller reshaper 1 positioned at bottom and position
In the two-way bumper jar on top, wherein, two-way bumper jar include to lower and on be linked in sequence successively self-packer 2, multistage liquid
Pressure propeller 3, anchor group 4, vibration device 5, compression relief cock 6 and pipe nipple variable buckle.During site operation, in the order described above will
All parts are sequentially connected, and topmost reconnect tubing string and are lowered in well.Wherein:
Circular roller reshaper 1
Circular roller reshaper 1 is located at the foot of whole system, and its outer surface is covered with cydariform roller, is mainly connect by it
At tactile casing deformation, and rise to outwards squeezing at undergauge, cydariform roller is rotatable so that overall structure frictional resistance little,
Laborsaving, Workover Effect is good.
Self-packer 2
Self-packer 2 includes body, flange and sealing member, and the situation running into bit freezing in work progress can be by from encapsulation
Put the function of playing jarring releasing.
Multistage hydraulic propeller 3
Multistage hydraulic propeller 3 is the power source of whole system, and its structure is by orderly for multiple hydraulic cylinders tandem compound
Together, huge downward motive force is produced by it, promote circular roller shaper to repair at set change.
Anchor group 4
On the angle of rake top of multistage hydraulic, the outer surface of anchor has uniformly been covered with horizontal piston to anchor group, and leads to
Cross piston to be supported on internal surface of casing, so that whole system is relatively fixed with oil well casing, using anchor group propping up as power
Support point implements downwards active force it is ensured that multistage hydraulic propeller is reliable.
Vibration device 5
Hydraulic super fishing jar can be adopted, using the angle of rake power of multistage hydraulic, certain frequency can be produced at stuck point
Vibration, play unfreezing effect.
Compression relief cock 6
It is to need in work progress at the scene to be repeated several times equipment in the top of anchor group, its function
Water in the tubing string of top drains and it also requires reliable close, and this function to be realized by compression relief cock.
Self-sealing two-way vibration casing repairing device be according to oil well casing necking deformation problem recent development, develop new
Multiple key technologies are invented and have been innovated by type well workover technology, and several aspects have great breakthrough, solve multinomial
A guardian technique difficult problem, have passed through and carry out ground experiment and field test for more than ten times, tests more than 10 mouths in Liaohe Oil Field within 2015
Well, success rate 85%, the level of technology is state-of-the-art at home and abroad, and repairing effect is also best, well workover speed
It is the fastest.
The maximum feature of the application is to be competent to advance and retreat -at will, and has the ability of quick repairing sleeve during construction.Encounter little
The curved and suitable bad position that can disposably repair needs than more serious well, has repaiied rear gas injection, pressure break also will not rebound, some wells
Oil reservoir lower bound repaiied by needs, and prior art does not have such repair ability it is likely that so that this well is scrapped.Because existing grappling
Device is that ram's horn shape can not be pulled out out in well it is easy to be stuck in.The self-sealing two-way vibration casing repairing device of the application is strip
Shape, will not enter in borehole it is possible to repair shaft bottom.Once there occurs Ka Jing, with mentioning safety marginses on ground machine,
Nor in the case of unblock, kayser can be exited by instrument itself.Detailed process is first wellhead sealing device to be shut (premise
It is to have wellhead sealing device), then beaten with ground cementing truck huge discharge is counter, pressure gets to 5-10mpa, by instrument itself
Self-packer, shuts upstream switch, and the strength by vibration device on self-sealing two-way vibration casing repairing device shakes the post that shakes
Swash and above push away, opening ground wellhead sealing device and returning to former suspending weight is unfreezing success.This device also ensure that while unfreezing and applies
The safety of work, avoids causing secondary injury to well simultaneously, thus oil supply well brings bigger economic benefit.
Certainly, the principle of the present invention will not change, CONSTRUCTED SPECIFICATION and embodiment can with described in non-limiting example mode
It is very different with diagrammatic.
