Description
Technical field
The utility model discloses a kind of tools for having both set milling and repairing top of fish function；Belong to drilling technology field.
Background technique
In oil drilling process, especially new exploratory area, during drilling operation due to lack to subsurface geological structure,
The enough understanding of lithological characteristic, drilling tool are improper and fall and be stuck in well due to material self problem or manual operation.In the mistake
Cheng Zhong, because the drilling tool that accident is fallen in well is referred to as underground fish.
It is main to the salvaging of fish in such a way that first set milling is salvaged again at present, that is, it is taking out blocked portion point or is burying a little with upper tube
After column, cement, desilting, gypsum and the calcium carbonate for causing blocked portion between underground fish and pit shaft in annular space are removed by casing section mill
The hard objects such as crystallization, are being salvaged, but are encountering the irregular shape of top of fish, i.e. dead fish, then are difficult to salvage, at this moment need elder generation
It is being salvaged after being repaired to top of fish.
In the prior art repair top of fish and set milling is often divided into two steps, using two kinds of tools, i.e., first descend milling pipe, to then exist
The top of fish of deformation is modified in top of fish repair next time, is made its rule, is then salvaged fish with fishing socket, need three
It is bored under time, activity duration and cost are all higher, and especially in deep-well and ultradeep well, cost and time increase obviously, reduce
Salvage efficiency.
Utility model content
