Abstract
The utility model relates to a fishing tool for treating oil, gas and water well downhole drilling tool junk. The existing fishing tool is partially designed into a replaceable part, and different fishing parts are assembled at the position of a fish head according to the shape of the fish head of the underground fish. When the fishing cone mandrel is provided with replaceable cones with different sizes, drill rods and drill collar fishing cones with different diameters are formed; when the fishing cone is assembled with milling cones of various specifications, the milling cones of different specifications are formed; when the lower part of the fishing cone is connected with a straight water hole guide cone or a deviated water hole guide cone, different types of fishing cones are formed. This allows a kit to have multiple fishing functions.
Description
The utility model relates to a kind of handling oil, water, gas well down-hole equipment accident, is particularly suitable for carrying out from the fish endoporus instrument of fishing.
Existing oil, gas, well down-hole equipment fish fishing tool have die nipple, salvage anchor etc.Because the limitation in the use in their designs, the fishing tool function singleness when salvaging the down-hole equipment fish of different size, needs to change different fishing taps or salvages anchor.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of simple in structure, dependable performance is provided, can really play a body multifunctional, salvage effective, can form dissimilar salvaging fish instruments according to diameter, the form of down-hole fish.
The purpose of this utility model can reach by following measure: this multi-functional salvaging is bored its overall structure and is made up of upper, middle, and lower part.Top is made up of the tool joint main body.Its principal character is that one is repeatedly used.The middle part is three kinds of interchangeable salvaging bodies that drag for awl, mill the awl composition, and its principal character is to salvage body can assemble different salvaging awls according to fish.The bottom is a leading cone, and its principal character is to match straight hydrophthalmia or inclined to one side hydrophthalmia leading cone according to fish position in well.
The multi-functional salvaging awl of the utility model can be assembled interchangeable salvaging body according to down-hole equipment fish situation, and the drilling rod, the drill collar that constitute different-diameter are salvaged awl.Milling awl in the assembling can be to the reparation of fish head.Inclined to one side hydrophthalmia leading cone is salvaged the fish that is in the off-normal position, down-hole in the assembling.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the structural representation of the multi-functional salvaging awl of the utility model;
Fig. 2 mills the structural representation of awl for the utility model;
Fig. 3 is the structural representation of the multi-functional salvaging awl of the inclined to one side hydrophthalmia of the utility model.
Drawing is described as follows: salvage tap web axle 1, thread protector 2, interchangeable cone 3, O RunddichtringO 4, leading cone 5, mill awl 6, hydrophthalmia leading cone 7, anti-down spiral shell Xiao 8 and tooth embedding 9 constitute multi-functional salvaging awl partially.
The top that the utility model is salvaged awl is to salvage the cone assembly, and by salvaging tap web axle 1, thread protector 2, axle are provided with tooth embedding 9, cone, connection screw thread and seal groove and constitute.The middle part is the interchangeable cone 3 of assembling on the axle cone, and the axle bottom connects and composes multi-functional salvaging awl by thread and leading cone 5.When salvaging fish, top and the drill string foot that will salvage awl earlier connect, then in company with drill string G.I.H top of fish position.By the leading cone guiding, interchangeable salvaging awl is inserted the fish head, put suitable pressure, rotate drill string and make salvaging awl in down-hole reach the purpose of salvaging the down-hole fish with a fish thread making; When need are repaired the fish head, salvaging the awl that mills that can assemble all size on the cone, constitute the awl that mills of different size; Be in the down-hole as fish and depart from the well center, assemble inclined to one side hydrophthalmia leading cone this moment, find the fish head, and will salvage awl and insert thread making in the fish head, reach the purpose of salvaging down-hole fish by the size of regulating mud flow rate.
The utility model compared with prior art has following advantage: simple in structure, easy to assembly easy and simple to handle, dependable performance can be according to the trouble of lost tool in hole difference, and apolegamy is assembled into various effective fishing spears, and it is very good therefore to salvage effect.
