Mechanical type internal cutter is from sleeve pipe, oil pipe, the inner a kind of mechanical type cutting tool carrying out cutting of drilling rod.For preventing cutting to sleeve pipe, tubing coupling, during cutter G.I.H, should collar location be avoided, can support the use with box cupling seeker when having ready conditions.During as connected fishing spear, can propose outside well together with internal cutter, not need independent salvaging, fishing tool also can be descended separately to pull out by the fish of cutting off.
Mechanical type internal cutter, mechanical type external cutter and hydraulic external cutter are all rely on the rotating speed provided by rotating disk to produce cutting speed cutting tubing string, and hydraulic external cutter just relies on hydraulic anchorage hydraulic external cutter.In addition, this three is in the process of cutting tubing string, and cutter not only produces radial motion, and produces axially-movable.
Utility model content
The utility model is intended to the defect overcoming existing cutting method, provides a kind of dependence hydro powered turbine thus produces rotary motion cutting tubing string, and ensureing that cutting position does not produce the device moved axially.Its technical scheme adopted is as follows:
Mechanical internal cutter, comprises cylindrical shell, grappling turbine installation auxiliary frame, slips, claw arm, grappling turbine, grappling reduction torsion spring, grappling turbine installing rack, main spring packing ring, main spring, thrust bearing bearing, thrust bearing, cutting auxiliary turbine installing rack, cutting auxiliary turbine, swivelling tool-holder, cutter, cutter support plate, spring leaf, blade bearing, mandrel.Described claw arm is connected with claw by T-slot, and be arranged on cylindrical shell, described grappling turbine is arranged on grappling turbine installing rack, and be interconnected with grappling reduction torsion spring, described grappling turbine installing rack is arranged on grappling turbine top, and with grappling turbine, auxiliary frame is installed and is interconnected, thus support grappling turbine, described main spring its lower part contacts with cylindrical shell, and hold main spring on top, thrust bearing bearing bottom contacts with main spring, the latter half of thrust bearing is fixed on top, described cutting auxiliary turbine installing rack is in the first half of bottom installed thrust bearing, cutting auxiliary turbine is installed on its top, described swivelling tool-holder is arranged on cutting auxiliary turbine installing rack, and mounting cutter in cutter groove thereon, described cutter support plate one end is connected with cutter, the other end is arranged on blade bearing, described spring leaf is arranged on blade bearing, and the other end contacts with cutter support plate, described blade bearing is arranged in mandrel exterior rectangular channel.
The utility model tool has the following advantages: except the rotating speed cutting tubing string provided except adopting rotating disk, use water conservancy to promote turbine and produce rotation, and in the process of cutting, ensure that the axial location cut does not change, thus the efficiency of cutting tubing string is significantly improved.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the utility model is described in further detail:
As shown in Figure 1, mechanical internal cutter, comprises cylindrical shell 1, grappling turbine installation auxiliary frame 2, slips 3, claw arm 4, grappling turbine 5, grappling reduction torsion spring 6, grappling turbine installing rack 7, main spring packing ring 8, main spring 9, thrust bearing bearing 10, thrust bearing 11, cutting auxiliary turbine installing rack 12, cutting auxiliary turbine 13, swivelling tool-holder 14, cutter 15, cutter support plate 16, spring leaf 17, blade bearing 18, mandrel 19.Described claw arm 4 is connected with claw 3 by T-slot, and be arranged on cylindrical shell 1, described grappling turbine 5 is arranged on grappling turbine installing rack 7, and be interconnected with grappling reduction torsion spring 6, described grappling turbine installing rack 7 is arranged on grappling turbine 5 top, and with grappling turbine, auxiliary frame 2 is installed and is interconnected, thus support grappling turbine 5, described main spring packing ring 8 bottom contacts with cylindrical shell 2, and hold main spring 9 on top, thrust bearing bearing 10 bottom contacts with main spring 9, the latter half of thrust bearing 11 is fixed on top, described cutting auxiliary turbine installing rack 12 is in the first half of bottom installed thrust bearing 11, cutting auxiliary turbine 13 is installed on its top, described swivelling tool-holder 14 is arranged on cutting auxiliary turbine installing rack 12, and mounting cutter 15 in cutter groove thereon, described cutter support plate 16 one end is connected with cutter 15, the other end is arranged on blade bearing 18, described spring leaf 17 is arranged on blade bearing 18, and the other end contacts with cutter support plate 16, described blade bearing 18 is arranged in the outer rectangular groove of mandrel 19.
The box be connected with drilling rod is arranged at its top of mechanical internal cutter, and bottom thread connects guide shoe, and miscellaneous part is all enclosed within mandrel, and there is hydrophthalmia at mandrel center, can circulate.When desired depth transferred to by instrument, start to input circulation fluid, grappling turbine 5 rotates under the impact of circulation fluid, claw arm 4 is driven outwards to move by side helicla flute, claw arm 4 drives slips 3 to produce radial motion, final slips 3 will contact in tubing string, and now transferring mechanical internal cutter can be anchored on mechanical internal cutter on tubing string.Strengthen circulating fluid volume, cutting auxiliary turbine 13 accelerates to rotate, by cutting auxiliary turbine installing rack 12, its rotary motion is passed to swivelling tool-holder 14 by cutting auxiliary turbine 13, swivelling tool-holder 14 carry its tools 15 fast rotational, thus cutting tubing string, mechanical internal cutter is transferred, thus be with each part that moving mandrel 19 and mandrel 19 are installed to produce axially-movable, the axially-movable of cutter support plate 16 and blade bearing 18 makes cutter 15 produce radial motion, cutter 15 is overhanging, thus increases the radial feeds of cutter 15, until cut off tubing string.After tubing string cutting, reduce circulating fluid volume, thus the cutting speed that slows down, the cutting until stop the rotation, above carries mechanical internal cutter, slips 3 is contacted with claw arm 4 and loosens, under the effect of grappling reduction torsion spring 6, grappling reduction torsion spring 6 drives grappling turbine 5 to reversely rotate, thus drives slips 3 and claw arm 4 to produce radial motion, terminates anchoring states.
Be illustrated the utility model by way of example above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
