Description
Technical field
The utility model relates to petroleum natural gas exploration field, specifically, is a kind of anti-lost strong magnetic fishing rod being applied to oil and gas exploration.
Background technology
Along with the development of petroleum exploration and development technology, horizontal well, directional well, high angle hole increasing number, lower bridging plug, bores the important means that bridging plug becomes oil, gas well exploitation.But easily cause shaft bottom to block along with a large amount of slip segments boring the appearance of mill bridging plug, how to utilize effective method slips fragment to be salvaged to the emphasis becoming oil, gas well exploitation.
The oil pipe that the underground work of another aspect accompanied by long-term occurs, casing failure create a large amount of chip, cause multiple difficulty to the production in later stage and the reparation of Oil/gas Well.Utilize merely the operation of well-flushing bulk chip cannot be recycled well at horizontal well, directional well and high angle hole, be badly in need of utilizing the fishing tool of specialty to carry out chip salvaging.
Conventional strong magnetic die only has front tool distributed magnetic field, and magnetic field range is little, and magnetic force is weak, salvages limited in one's ability.The strong magnetic fishing tool of part is at instrument surrounding distributed magnet, but the installation of magnet relies on the instruments such as screw to fix, and down-hole situation is complicated, easily causes toner screw, thus causes magnet to drop, for subsequent job causes great constructional difficulties.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, devises that a kind of magnetic field range is large, magnetic force is strong, the strong magnetic fishing rod of Anti-fall.
Anti-lost strong magnetic fishing rod of the present utility model, comprise the body of rod, described body of rod side-wall shaft is to being provided with mounting groove, the width of described mounting groove bottom land is greater than the width of notch, be provided with permanent magnet in described mounting groove, the width of described permanent magnet is greater than the width of mounting groove notch, and described mounting groove one end is provided with installing port, the width of described installing port is more than or equal to the width of mounting groove bottom land, and the length of described installing port is more than or equal to the length of permanent magnet.
Preferably, described mounting groove is dovetail groove or T-slot.
Preferably, described mounting groove is arranged on the bottom land of the V-shaped groove that body of rod sidewall is arranged.
Preferably, in described mounting groove, permanent magnet is connected with multiple, and the magnetic pole of adjacent permanent magnets end is contrary.
Preferably, the mounting groove bottom land corresponding with described installing port is provided with screw, and the distance between described screw and installing port the inner is less than the length of permanent magnet.
Preferably, described installing port is positioned at the upper end of mounting groove.
Preferably, described mounting groove is provided with multiple.
The beneficial effects of the utility model are: the permanent magnet of anti-lost strong magnetic fishing rod is arranged in the mounting groove of sidewall setting, mounting groove bottom width mouth is narrow, and permanent magnet width is greater than notch, permanent magnet is made to be fixed in mounting groove with the form buried underground, can not come off, and there is no the fixed parts such as screw, also can not there is coming off of fixed part.Permanent magnet loads in mounting groove by the installing port that one end is arranged or removes in mounting groove, and permanent magnet dismounting easily, is convenient to assembling and the maintenance of fishing rod.
Mounting groove is arranged in V-shaped groove, increases the coverage in magnetic field, ensure that maximum adsorption range, and when down-hole is salvaged, iron block is adsorbed on permanent magnet, and permanent magnet is also be arranged in V-shaped groove simultaneously, reduces risk fishing rod being put forward iron block accidental in process.
Permanent magnet is contacted in groove, and adjacent permanent magnets attracts each other, and adds the overlay length in magnetic field, area, too increases the intensity in magnetic field, improves fishing rod absorption property.
Mounting groove on installing port, built with screw, stops permanent magnet, avoids it to move to installing port place, come off from installing port.
Mounting groove arranges multiple, makes body of rod sidewall circumference all can install permanent magnet, magnetic field range full angle is covered, further increases adsorption range, avoids occurring salvaging dead angle.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of anti-lost strong magnetic fishing rod;
Accompanying drawing 2 is the cross-sectional schematic of anti-lost strong magnetic fishing rod.
Detailed description of the invention
Anti-lost strong magnetic fishing rod of the present utility model, as shown in Fig. 1 to 2, comprise the body of rod 1, the body of rod 1 side-wall shaft, to being provided with mounting groove 2, is provided with permanent magnet 3 in mounting groove 2, is salvaged by foreign material such as permanent magnet 3 pairs of down-hole iron blocks.For adapting to the subsurface environment of high temperature, permanent magnet 3 can select resistant to elevated temperatures high temperature permanent magnets iron.
Mounting groove about 2 two ends all do not arrive the end of the body of rod 1.
Mounting groove 2 can be the flute profile that the slot bottom width such as dovetail groove, T-slot is greater than width of rebate.The width of permanent magnet 3 is greater than the width of mounting groove notch, and permanent magnet 3 can not be deviate from from the notch of mounting groove 2.Permanent magnet 3 cross section can be identical with the cross-sectional sizes of mounting groove 2, shape, and be slidably mounted on closely in mounting groove 2, fastness is stronger.
Mounting groove 2 one end is provided with installing port 4, and the width of installing port 4 is more than or equal to the width of mounting groove 2 bottom land, and the length of installing port 4 is more than or equal to the length of permanent magnet 3.By installing port 4, permanent magnet 3 can be encased in mounting groove 2, then slides into the correspondence position in mounting groove 2.
The body of rod 1 sidewall is provided with V-shaped groove, mounting groove 2 is arranged on the bottom land of V-shaped groove 5, and V-shaped groove 5 forms an enlarging and holding tank, increases magnetic field coverage, make the iron block be adsorbed on permanent magnet 3 be temporarily stored in wherein, reduce risk fishing rod being put forward iron block accidental in process.
Install multiple permanent magnet 3 in mounting groove 2, permanent magnet 3 is contacted, and the magnetic pole of adjacent permanent magnets 3 end is contrary, attracts each other and forms magnet string, increases the overlay length in magnetic field, area and intensity.
For preventing installing port 4 place of permanent magnet 3 slideway mounting groove 2, and come off from installing port 4, mounting groove 2 bottom land at installing port 4 place is provided with screw 6, distance between screw 6 and installing port 4 the inner is less than the length of permanent magnet 3, make screw 6 fore-set permanent magnet 3, make permanent magnet 3 be positioned at the narrow part of mounting groove 2 bottom land wide notch always.
At one week of the body of rod 1 sidewall, mounting groove 2 arranged multiple, installs the magnet string of multiple permanent magnet 3 composition, magnetic field range multi-angle is covered, further increases adsorption range in each mounting groove 2, avoided occurring salvaging dead angle.
Be connected on drill string on the body of rod 1 top during use and be sent to down-hole, fishing rod, proposes after having salvaged by iron block and can be adsorbed onto on the permanent magnet 3 in V-shaped groove 5 by magnetized various foreign material in down-hole by fishing rod from well.
