Description
Technical field
The utility model is related to oil field well workover tools, specifically rotate make-up and change top of fish fishing integrated work
Tool.
Background technology
With the continuous development of Exploitation Level of Oilfield, oil exploitation technology is also being constantly progressive, not only completion mode, well bore
Structure is varied, and mating oil recovery, water filling, steam injection string and its downhole tool also a multitude of names, the production in oil field
In the process, trouble of lost tool in hole accident is often resulted in when, causes top of fish different, falls well casing column or tool may be because of many reasons
It causes to be stuck in down-hole casing.Therefore, it is necessary to use suitable fishing tool to falling well casing column or tool progress by card
It salvages, to realize unfreezing, restores the integrality of pit shaft.
During salvaging unfreezing, fishing socket can be transferred to the top of top of fish by working string, then to salvaging
Cylinder applies pressure so that top of fish enters in dipper, salvages trouble of lost tool in hole from the outside of top of fish, this belongs to outer fishing；It can also lead to
It crosses working string to transfer fishing spear to the top of top of fish, then pressure is applied to fishing spear so that fishing spear enters the interior of top of fish
Chamber salvages trouble of lost tool in hole from the inside of top of fish, this belongs to interior fishing, after top of fish is salvaged lives, you can above carry in well tubing string and
Fishing tool is completed to salvage unfreezing operation.
Although there are many fishing tool type of onsite application at present, mating fishing tool is still still far from perfect, for
The junk of special top of fish, either outer fishing or interior fishing just must the advanced line replacements of tripping in tool without suitable fishing tool
It after new top of fish, then is salvaged, this certainly will cause to increase underground work process, extend the Downhole Construction period, increase operation
Cost influences the normal production of oil-water well.
Therefore, for the junk with special top of fish, top of fish and the fishing tool one-trip string using standard how to be replaced
Fishing is completed, is oil well repairing operation technical staff's problem to be solved.
Utility model content
