Embodiment
The hydraulic cutter device of the deep-sea Casing-Cutting includes shell 1, connecting cylinder 2, joint 3, hollow shaft 4, upper bush 5th, middle sleeve 6 and lower sleeve 7.The top of shell 1 is provided with joint 3 by the screw thread of connecting cylinder 2;Baffle is provided with the inwall of joint 3 Hole 8, baffle hole 8 is bellmouth.Upper bush 5 and middle sleeve 6, upper bush 5 and middle set are provided with the shell 1 of the lower section of baffle hole 8 It is threadedly coupled between cylinder 6.Up-thrust bearing 11, up-thrust bearing 11 are equipped with by shading ring A9 and shading ring B10 on upper bush 5 Turbine assembly 14 is equipped with by alignment bearing A12 and alignment bearing B13 on the upper bush 5 of lower section, turbine assembly 14 includes rotor And stator.
Screw thread is provided with shell end cap 15 in the lower port of shell 1, and the lower end of middle sleeve 6 is extended to through shell end cap 15 The outer end of shell 1, extend to screw thread on the middle sleeve 6 of the outer end of shell 1 be provided with lower sleeve 7, the circumference of lower sleeve 7 it is uniform multiple There is cutter hole 16.Lower thrust-bearing 17, lower thrust-bearing 17 and shell end cap 16 are housed on the middle sleeve 6 of the top of shell end cap 15 Between middle sleeve 6 on be provided with shading ring C18.
The port of upper bush 5, which is provided with axle sleeve disk 19, upper bush 5, is provided with hollow shaft 4, and one end of hollow shaft 4 is passed through Axle sleeve disk 19 extends to the top of baffle hole 8, and the top of hollow shaft 8 is installed with baffle disk 21, baffle disk 21 by bolt 20 Section is trapezoidal, and the shape of baffle disk 21 is corresponding with baffle hole 8, is to be slidingly sealed connection between baffle disk 21 and baffle hole 8. Spindle springs 22 are housed in the hollow shaft 4 between baffle disk 21 and axle sleeve disk 19.
The other end of hollow shaft 4 is extended in lower sleeve 7 through middle sleeve 6, the termination of hollow shaft 4 extended in lower sleeve 7 It is fixed with and cuts somebody's hair 23, it 23 is closing waist bullet to cut somebody's hair.Cut somebody's hair between 23 and lower sleeve 7 and cutter are provided with by cutter spring 25 24, one end of cutter 24 is extended in cutter hole 16, and the other end of cutter 24 is connected with 23 sliding contacts of cutting somebody's hair.
The cutter 24 of the cutter device are made up of cutter head, cutter hub and knife tail, and the cutter head of front end is hard alloy, can make to cut Cut more efficient, stage casing is that cross makes cutter horizontal movement more stablize, and the knife tail of rear end is arc-shaped, passes through arc-shaped Cooperation at the closing waist of knife tail and 23 arcs of cutting somebody's hair, so that the slip between both is more smoothly, and then makes cutter 24 It is easier to be pressed out to outside cutter hole 16.The flange closed on cutter hub at knife tail, in the presence of cutter spring 25, it is ensured that cutting Knife 24 in a non-operative state with cut somebody's hair 23 contact, and to cutter 24 formation support so that cutter 24 keep level State.
Upper runner hole is respectively arranged with the shading ring A9 and shading ring B10 of the cutter device, upper bush 5 is provided circumferentially about There are 4 upper bush runner holes 26, upper runner hole is connected with upper bush runner hole 26.
Lower flow channel hole is respectively arranged with shading ring C18 and shell end cap 15, middle sleeve 6 is provided circumferentially about set in 4 Cylinder runner hole 27, lower flow channel hole is connected with middle sleeve runner hole 27.
When the cutter device works, drilling fluid is entered by joint 3;Due to the pressure of drilling fluid, baffle disk 21 drives hollow Axle 4 and cut somebody's hair 23 axially downward in sleeve and compress spindle springs 22, cutting somebody's hair 23 pairs for being moved down during this is cut The formation radial compression of cutter 24, so that cutter 24 are progressively pushed out into the outer end of cutter hole 16 and connect with sleeve pipe 28 to be cut Touch, this process, cutter spring 25 23 is moved down and gradually compressed with cutting somebody's hair.While cutter 24 are extruded, drilling well Liquid acts on turbine assembly 14 through upper runner hole and upper bush runner hole 26 and drives it to rotate, and then drilling fluid is through middle sleeve Runner hole 27 and the discharge of lower flow channel hole.Turbine assembly 14 and upper bush 5 is driven to rotate under drilling fluid effect, and then cover in driving Cylinder 6 and lower sleeve 7 are rotated, and thus drive cutter 24 to carry out rotation cutting to sleeve pipe 28 to be cut.Rotating the mistake of cutting Cheng Zhong, makes to cut in the presence of 23 because the pressure of drilling fluid makes hollow shaft 4 remain a descending trend, and then cutting somebody's hair Cutter 24 remains the trend of a feed, until sleeve pipe 28 is cut through(Dialysis).
The baffle disk 21 of the cutter device and the distance in baffle hole 8 be equal to the points of a knife of cutter 24 to the outer wall of sleeve pipe 28 away from From.After the point of a knife of cutter 24 extend out to 28 outer wall of sleeve pipe, baffle disk 21 is descending just to coincide to form close with baffle hole 8 Envelope, now, the change according to drilling hydraulic force value, you can judge whether sleeve pipe 28 cuts completion.
After the completion of sleeve pipe 28 is cut, drilling fluid is suppressed in stopping, and the pressure of baffle disk 21 disappears, in the work of spindle springs 22 Up with lower hollow shaft 4, while hollow shaft 4 is up, 23 extruding forces acted on cutter 24 of cutting somebody's hair also progressively disappear, In the presence of cutter spring 25;The retraction of cutter 24 resets, and so far cuts work and completes.The cutter device is simple in construction, uses It is convenient, solve existing tool construction complexity, complex operation, it is impossible to judge whether sleeve pipe completely cuts through, be easily caused cutting thing Therefore, and cutting efficiency it is low the problem of.The cutter device using turbine band cutter due to being rotated, and moment of torsion loses in transmittance process It is small, the cost of casing-pipe cutting is reduced, the efficiency of Casing-Cutting is effectively increased;Deep-sea Casing-Cutting is particularly suitable for use in use.
