Description
Technical field
The utility model be oilfield oil well casing damage after the device of reparation is carried out to it, be that a kind of will block pipe
The anchor being located on casing.
Background technology
After casing damage in oil-water well, to use casing patch method that will be subsidized at casing collapse, prevent casing leakage,
Casing patch will be blocked under pipe at casing collapse, between pouring into casing by cement mortar and block pipe, after cement slurry sets, be made
Casing consolidates integrally with pipe is blocked, intact to be repaired at casing collapse, and oil-water well is enable normally to produce.Using this side
To make to block the mend that pipe is located in casing when method casing repairing.It is mud of fetching water in casing that positioning, which blocks the measure of pipe, at present
Plug makes to block to positioning is supported behind cement plug face under pipe, and this localization method is also pasting in addition to the work for having cementing plug
Plugging needs cement plug boring the work opened after subsidizing on casing, and construction cost is high, and the well workover time is long, worker's working strength
Greatly, workover cost is high.A kind of measure of also having that positioning at present blocks pipe is the back-up sand in well, is made to block under pipe to being propped up behind sand face
Support positioning, this localization method equally exist above-mentioned problem.To solve the above-mentioned problems, it is used in casing repairing
Anchor is connected to and blocks under pipe by anchor, so that anchor is worked after G.I.H, will block pipe and is located in what needs were repaired
Casing position.But anchor used at present, after getting well casing patch, the interior internal diameter in anchor is small, and tripping in from now on point is adopted point
Note tool will be greatly affected, because the diameter of separate production and injection tool is smaller, tool is more difficult to design and process, its reliability
Also can be poorer, service life is also short, and the production cycle of oil-water well is also short.
