Abstract
The utility model discloses a drill post type magnet fisher, including the magnetism drilling string, magnetism drilling string inner chamber link up and is provided with mud circulation channel, is provided with from bottom to top's spiral delivery passage on the magnetism drilling string outer wall, and magnetism drilling string lower extreme is the link, and the upper end is provided with the salvage and deposits the recess, and the salvage is deposited the recess and is arranged in depositing the salvage of carrying through spiral delivery passage in the spiral delivery passage. The utility model discloses under the horizontal drilling condition, can stir the junk, load the junk through gluing the magnetism junk and collecting, reach and satisfy the condition of digging out a hole.
Description
Technical field
The utility model relates to a kind of oil fishing tool, particularly relates to a kind of drill stem type magnet fisher, for solving the gear wheel accident occurred in the drilling well of horizontal segment PetroChina Company Limited..
Background technology
Existing fishing tool all adopts Action of Gravity Field.Such as, the disclosed gear barrel of China Patent Publication No. " 1912333 ", publication date is 2007-02-14.This instrument have employed that the locking of inside and outside longitudinal force just can be pressurizeed, rotated, turn on pump circulation well cleanup, can process in well bore collapse, undergauge, sand bridge, sand setting Various Complex situation.After interior longitudinal force being opened after caber, in instrument, longitudinal gravity compresses (14) tapering cover pricker downwards guiding obliquely and produces lateral deformation and become 360 degree of comprehensive baskets of hugging gear wheel in dipper.To bore under one time and the time of trip-out just can successfully, disposablely intactly to pull 1 ~ 3 gear wheel out.This instrument interchangeable tapering cover pricker is reused.
Such technology is relatively more successful to straight well and little Wells, but is not suitable in horizontal drilling, when occurring rock bit accident at horizontal segment in horizontal drilling, or occurring metal fish accident, conventional Fishing Tools, wasting time and energy and even salvaging failure.
Summary of the invention
The purpose of this utility model is the problems referred to above overcoming prior art existence, provides a kind of drill stem type magnet fisher.The utility model, under horizontal drilling condition, can stir junk, by sticky magnetic junk and collection filling junk, reaches satisfied trip-out condition.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of drill stem type magnet fisher, it is characterized in that: comprise magnetic drill string, described magnetic drill string inner chamber is through is provided with mud circulation passage, magnetic drill string outer wall is provided with helical feed passage from bottom to top, magnetic drill string lower end is link, upper end is provided with salvaging thing and deposits groove, and salvaging thing is deposited groove and is arranged in helical feed passage for depositing the salvaging thing carried by helical feed passage.
It is multiple that described salvaging thing deposits groove.
Described salvaging thing deposits groove not at grade.
The size that described salvaging thing deposits groove is mated with drill bit size.
Described magnetic drill string lower end is internal thread link.
Employing the utility model has the advantage of:
One, the magnetic drill string outer wall in the utility model is provided with helical feed passage from bottom to top, junk can be stirred by this structure, be convenient to outwards carried by helical feed passage thus discharge.
Two, the magnetic drill string in the utility model, can glue magnetic junk by magnetic drill string, is convenient to equally outwards carried by helical feed passage thus discharge.
Three, the salvaging thing arranged in the utility model deposits groove, can coordinate with helical feed passage, for depositing the salvaging thing carried by helical feed passage, and then satisfied trip-out condition.
Four, in the utility model, it is multiple that salvaging thing deposits groove, and salvaging thing deposits groove not at grade, adopts this structure, can ensure to deposit more salvaging thing, further ensure and can meet trip-out condition.
Five, adopting the utility model, under horizontal well condition, for solving the gear wheel accident occurred in the drilling well of horizontal segment PetroChina Company Limited., ensureing that gear wheel is taken a seat.

Be labeled as in figure: 1, magnetic drill string, 2, mud circulation passage, 3, helical feed passage, 4, link, 5, salvage thing and deposit groove.
Detailed description of the invention
A kind of drill stem type magnet fisher, comprise magnetic drill string 1, described magnetic drill string 1 inner chamber is through is provided with mud circulation passage 2, magnetic drill string 1 outer wall is provided with helical feed passage 3 from bottom to top, magnetic drill string 1 lower end is link 4, upper end is provided with salvaging thing and deposits groove 5, and salvaging thing is deposited groove 5 and is arranged in helical feed passage 3 for depositing the salvaging thing carried by helical feed passage 3.
Preferred embodiment of the present utility model is, described salvaging thing deposits groove 5 for multiple.As shown in Figure 3, the salvaging thing in figure is deposited groove and is set to four.
Further, described salvaging thing deposits groove 5 not at grade.
Another preferred embodiment of the present utility model is, the size that described salvaging thing deposits groove 5 is mated with drill bit size.
Another preferred embodiment of the present utility model is, box structure is arranged in described magnetic drill string 1 lower end, is internal thread link.
Operating principle of the present utility model is as follows:
Under horizontal drilling condition, adopt magnetic drill string 1 to stir junk, glue magnetic junk by magnetic drill string 1 simultaneously, and be upwards transported to by helical feed passage 3 and salvage thing and deposit groove 5, deposit groove 5 load junk until meet trip-out condition by salvaging thing.
