Description
Technical Field
The utility model relates to an oil field is salvaged junk kit in pit.
Background
The existing common tools for salvaging small-sized fallen objects in the underground operation of the oil field have the advantages that the multipurpose strong-magnetic salvaging device and the salvaging basket are used, sand is generated in most wells in the sandstone oil field, and the fallen objects cannot be effectively salvaged by the tools under the condition that the fallen objects are buried by sand during salvaging, so that the tools cannot directly contact the fallen objects and cannot be salvaged.
Disclosure of Invention
In view of this, the utility model provides a multi-functional smallclothes junk fisher solves the fishing tool commonly used of small-size junk is salvaged in current oil field borehole operation when meeting the sand and burying the serious condition, and the problem that the junk can't be fished out effectively to the fishing tool commonly used.
In order to achieve the above object, the multifunctional small fallen object fisher comprises: a cover mills a section of thick bamboo, its characterized in that:
the bottom of the sleeve milling cylinder is provided with a sawtooth structure;
when the falling objects are buried by the gravels, the milling sleeve is rotated, and the sawtooth structures are used for milling the gravels to expose the falling objects.
Preferably, a strong magnetic sleeve is fixed on the inner wall of the sleeve milling cylinder;
the strong magnetic sleeve is used for magnetically adsorbing the falling objects.
Preferably, the upper end of the milling barrel is connected with an upper joint;
the upper joint is used for connecting rotating equipment.
Preferably, the milling sleeve is internally provided with a central tube;
the central pipe is provided with a sieve pore;
and the sieve holes are used for filtering particle impurities which circulate to the milling barrel along with the backwashing well so as to prevent the circulating channel of the backwashing well from being blocked.
Preferably, the central tube is fixedly connected in the milling sleeve through the upper joint.
Preferably, the lower end of the central tube is located at the middle position of the milling sleeve.
The utility model discloses following beneficial effect has:
the utility model discloses with present fishing tool commonly used relatively, through the sawtooth structure of milling barrel head portion, will bury the back that falls the junk clearance below the grit falls, can make the junk expose to further in the mode through the backwash well is salvaged the junk circulation to milling barrel, until salvaging ground, thereby effectively solve the sandstone oil field and meet the problem that the junk can't be effectively fished out with the junk in sand buries the junk when salvaging.
Drawings
The above and other objects, features and advantages of the present invention will become more apparent from the following description of the embodiments of the present invention with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural view of the multifunctional small-piece falling object fisher according to the embodiment of the present invention.
Detailed Description
The present invention will be described below based on examples, but it should be noted that the present invention is not limited to these examples. In the following detailed description of the present invention, certain specific details are set forth in detail. However, for parts not described in detail, those skilled in the art can fully understand the present invention.
Furthermore, those skilled in the art will appreciate that the drawings are provided for purposes of illustrating the objects, features, and advantages of the invention and are not necessarily drawn to scale.
Also, unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is, the meaning of "includes but is not limited to".
Fig. 1 is a schematic structural view of the multifunctional small-piece falling object fisher according to the embodiment of the present invention. As shown in figure 1, the multifunctional small-piece junk fisher comprises a milling sleeve 2, wherein the bottom of the milling sleeve 2 is provided with a sawtooth structure 5; when the falling objects are buried by the gravels, the milling barrel 2 is rotated, and the sawtooth structures 5 are used for milling the gravels away to expose the falling objects.
In fig. 1, a strong magnetic sleeve 4 is fixed on the inner wall of the milling sleeve 2, and the strong magnetic sleeve 4 is used for magnetically adsorbing falling objects and preventing threads circulating into the milling sleeve 2 from falling off during reverse well washing.
In fig. 1, the upper end of a milling barrel 2 is connected with an upper joint 1, and the upper joint 1 is used for connecting rotary equipment.
In fig. 1, a milling sleeve 2 is provided with a central tube 3 therein, and the central tube 3 is provided with a sieve hole; the sieve pores are used for filtering particle impurities which circulate to the milling barrel 2 along with the backwashing well so as to prevent blocking a circulating channel of the backwashing well.
In fig. 1, a central tube 3 is connected and fixed in a milling barrel 2 by an upper joint 1. Specifically, the upper port of the central tube 3 is provided with external threads, while the inner wall of the upper joint 1 is provided with internal threads, and the two are in threaded connection.
In fig. 1, the lower end of the central tube 3 is located in the middle of the milling sleeve 2, so that a junk accommodating space is reserved in the inner cavity of the milling sleeve 2, and junk is circulated into the milling sleeve 2 during well back-flushing.
Specifically, the working process of the multifunctional small fallen object fisher of the present invention is described with reference to fig. 1:
before working, the upper joint 1 is connected to the bottommost end of the oil pipe and enters a well.
When the device works, an oil pipe rotating force is applied to the ground, the sawtooth structure at the bottom end of the milling sleeve 2 can mill the sand-buried part to expose fish (falling objects), then the well is washed back, the fish circulates into the milling sleeve 2 and is adsorbed on the strong magnetic sleeve 4 on the inner wall of the milling sleeve 2, and the falling objects are fished out; meanwhile, large-particle impurities in the circulating liquid flow of the backwash well can be filtered through the sieve holes in the central pipe 3 in the backwash well process, and the circulation channel of the backwash well is prevented from being blocked.
The above-mentioned embodiments are merely embodiments for expressing the invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several changes, substitutions, modifications, etc. can be made without departing from the spirit of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
