Description
Technical field
The utility model is related to the expandable casing patching instrument of oil-gas mining underground work, more particularly to a kind of reparation damages set
The expandable casing patching instrument of pipe.
Background technology
As the paces of exploration and development are continued to increase, the proportion such as directional well, high angle hole, horizontal well is also increasingly
Greatly, in drilling process, the abrasion, extruding to sleeve pipe are inevitable, and current casing failure is broadly divided into following three class：Due to corrosion
The presence of property medium, causes sleeve pipe to be revealed；Big by force intensity with well cementing process and formation creep causes sleeve pipe to sleeve pipe going into the well
Bad break；Because perforation maloperation causes sleeve pipe hole.
Currently for casing repairing, efficient method enters expansion tube under being, will repair set to needs under expansion subsidy instrument
The position of pipe, then promotes expansion cone extrusion expansion pipe so that expansion tube is adjacent to sleeve pipe, completes casing repairing.But repair at present
There are some defects in the expandable casing patching instrument for damaging sleeve pipe again：Scene application expansion subsidy technology main method be：Under it is swollen
Tube expansion, connecting rod connection expansion cone, to injected clear water in expansion tube and oil pipe, suppress expansion tube and drill through lower plug (Chen Ning expand
Pipe water-plugging technique is in application [A] Jilin Province's Science and Technology Association's low-carbon economy and the scientific development-Jilin Province of Jilin Oil Field the
Six Science and Technology Association of science and technology science nd Annual Meeting collection [C] Jilin Province:2010:3), this method needs two subjobs,
Efficiency comparison is low；A kind of expandable casing patching device disclosed in patent CN204532193, during work, above puies forward connecting tube, guiding expansion
Pipe is moved up, and completes expansion work, then moves down and rotate connecting rod, drives bottom bit operation, and plugging block is bored
Wear, realize expandable casing patching one-off construction, but the bit size in the work is significantly less than plugging block diameter, can so lead
The sleeve shrinking diameter after repairing is caused, unnecessary trouble is brought to follow-up underground work.
For the deficiency for repairing the expandable casing patching technology for damaging sleeve pipe at present, it is proposed that a kind of reparation damages the swollen of sleeve pipe
Tube expansion subsidizes instrument, on the basis of current expansion tube reparation damages casing operation, is pushed away using high pressure fluid reservoir inner high voltage liquid
Dynamic expansion cone so that expansion tube is close to damage sleeve pipe, will guide the Design of length of bar into consistent with the casing length for needing to repair,
Can just realize that expansion tube reparation damages the disposable operation of sleeve pipe.
The content of the invention
The purpose of this utility model be in order to overcome the shortcomings of it is existing repair damage sleeve pipe expandable casing patching technology exist,
There is provided a kind of expandable casing patching instrument repaired and damage sleeve pipe.
To achieve the above object, the technical scheme that the utility model is used is：
It is a kind of to repair the expandable casing patching instrument for damaging sleeve pipe, mainly by connecting tube, expansion tube, damage sleeve pipe, nut, stifled
Head, guiding bar, expansion cone, runner hole, locating piece and high pressure fluid reservoir composition；Locating piece and spiral shell are installed outside the connecting tube pipe
Cap, locating piece is located at connecting tube top, and nut is located at connecting tube bottom, and connecting tube pipe inner bottom part installs plug；The guiding bar
It is arranged on outside connecting tube pipe with expansion cone, guiding bar bottom is fixedly connected with expansion cone, guides bar, expansion cone and is connected tube wall
Between formed high pressure fluid reservoir, guiding bar can be moved up and down along connecting tube, and drive expansion cone along connecting tube in locating piece and spiral shell
Moved up and down between cap；The expansion tube is placed between damage sleeve pipe and connecting tube.
Further that the connection tube wall above the locating piece is provided with two symmetrical runner holes, runner hole it is straight
Footpath is 1cm.
It is further that the stroke L of the upper surface of the expansion cone to locating piece is 5m.
The beneficial effects of the utility model are：Operationally, by the instrument G.I.H to damaging sleeve position, Xiang Lian
Injection highly pressurised liquid in adapter pipe, highly pressurised liquid enters high pressure fluid reservoir by runner hole, and nut limitation expansion cone is descending, high pressure
Fluid reservoir inner high voltage liquid-driving guiding bar is moved up, and drives expansion cone to move up, until locating piece limitation expansion cone
Move up, stop injection highly pressurised liquid and above put forward connecting tube, expansion cone is continued to move up with connecting tube, and expansion cone is up
During extrusion expansion pipe, expansion tube is close to damage internal surface of sleeve pipe, with this reach repair damage sleeve pipe purpose, and should
The disposable operation of instrument, will not cause the sleeve shrinking diameter after repairing and leave the tool materials of remnants.
Advantage of the present utility model：The instrument can make expansion tube be close to damage internal surface of sleeve pipe, and the disposable operation of instrument is damaged
Hinder after casing repairing not undergauge, resided in well without remaining tool materials.
