Abstract

The utility model discloses a portable well repairing fishing drip, which is composed of a drill pipe short section and a drip, which are in screwed connection. One end of the drill pipe short section is a drill pipe female buckle, which can connect with a drilling string when going into a well; the other end another end is a drill pipe male buckle for connecting a fishing tool, the lower joint of the drill pipe short section is processed with screw thread so as to connect with the drip. One end of the drip is processed as a female buckle so as to connect with the drill pipe short section; the other end is a guide shoe. The utility model has a guidance function when a small diameter tube-type fall is fished in a big sleeve, which can prevent the fishing tool from inserting in a hohlraum to cause a failing fishing. Using the fishing drip causes the replacement of flip-chip fishing spear and slider fishing spear, the taking out of falls, and the withdrawing of tools to be convenient, so that a shear weld is not needed, and the fishing efficiency is greatly increased.

Description

Skirt is salvaged in the portable well workover
Technical field
The utility model relates to a kind of oil field well workover fishing tool, and skirt is salvaged in particularly a kind of portable well workover, is mainly used in and salvages minor diameter tubing junk in big sleeve pipe.
Background technology
General well workover fishing tool top connection is directly welded skirt so that instrument is introduced fish smoothly, but salvage successfully to trip out behind the instrument and fish taken out very difficulty, usually need and to take out after instrument or the skirt destruction, and get when changing instrument and weld skirt again, time-consuming, effort, cost height should use very inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of simple to operate, and skirt is salvaged in the portable well workover of reliable operation.This utility model is made up of drill pipe nipple and skirt two parts, and both adopt screwed connection.Drill pipe nipple one end is the drilling rod box, can connect with drill string when going into the well, and the other end is the drilling rod pin thread, is used to connect fishing tool, and the drill pipe nipple lower contact is connected with skirt.Skirt one end is processed into box, and to link to each other with drill pipe nipple, the other end is a guide shoe.The characteristics of this instrument be drill pipe nipple and skirt by screwed connection, during The field, fishing tool also screws with the screwed connection of drill pipe nipple bottom earlier, then fishing tool is penetrated in the skirt, skirt is again with drill pipe nipple lower contact screwed connection and screw.
The utility model compared with prior art, each parts is owing to be screwed connection, drags for and instrument can be withdrawed from after obtaining junk, other connects fishing tool, and needn't weld skirt on fishing tool.Prior art is dragged for the junk that obtains and often is difficult on ground withdraw from because skirt is welded on the fishing tool, at this moment skirt can only be sliced off, and looks for specialized factory's welding processing again, thereby cost is increased.Therefore this technology compared with prior art, it is convenient, fast to have a replacing instrument, the advantage that cost is low.
Description of drawings
Fig. 1 salvages the skirt structural representation for the portable well workover.
(1) is that drill pipe nipple, (2) are guide shoe for skirt, 3 among the figure.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: drill pipe nipple (1) one end is the drilling rod box, can connect with drill string when going into the well, the other end is a pin thread, is used to connect fishing tool, and drill pipe nipple (1) lower contact is processed with the screw thread that can be connected with skirt (2).Skirt (2) one ends are processed into box, and to link to each other with drilling rod, the other end is guide shoe (3).Characteristics of the present utility model are drill pipe nipples (1) with skirt (2) by screwed connection.Fishing tool penetrates fishing tool in the skirt (2) then earlier with drill pipe nipple (1) bottom screwed connection and screw during The field, and the same again drill pipe nipple of skirt (2) (1) lower contact screwed connection also screws.The utility model is applicable to that salvaging minor diameter tubing junk in big sleeve pipe plays guiding function, prevent that fishing tool from inserting annular space and causing the salvaging failure, even it is complicated that lock of tool drilling takes place.Adopt this salvaging skirt, make the replacing left hand fishing spear, slide block drags for lance, takes out junk, and it is very convenient to withdraw from instrument, need not to cut weldering, salvages efficient thereby improve greatly.
