Summary of the invention
The utility model technical problem to be solved is, provide a kind of and rotatablely creep into, efficiency of construction is high, drag for husky effective spiral drilling type sand bucket.
The spiral drilling type sand bucket of the utility model includes and is used for the water out adapter that is connected with the tubing string of transferring power, and water out adapter is provided with delivery port, and the water out adapter lower end is provided with valve seat and last valve; Last valve seat lower end connects the pull bar of hollow; Pull bar stretches in the pump barrel of sealing; The pull bar lower end connects plunger; Plunger is upper and lower mobile in pump barrel under the drive of pull bar, and axial limiting can be carried out to the pull bar lower end in the pump barrel upper end, can drive pump barrel one the same moving when promptly moving on to the pump barrel upper end on the pull bar lower end; Said pump barrel lower end connects cartridge, and the cartridge lower end is provided with down valve seat and following valve; Following valve seat lower end is connected with the core retainer plate pull bar of hollow, and core retainer plate pull bar lower end connects the spiral core retainer plate of a hollow, and spiral core retainer plate outer wall is provided with helicla flute; Be with a rotatable rotary tube in the periphery of spiral core retainer plate; The inwall of rotating cylinder is provided with the rotating dog that is placed in the above-mentioned helicla flute and distributes along helix; Rotating cylinder cooperates with spiral fluted through rotating dog with the spiral core retainer plate and forms screw pair, and the lower end of rotating cylinder connects drill bit.
Be provided with the key and the keyway that cooperatively interact between said pull bar and the pump barrel, to prevent the relative pull bar rotation of pump barrel.
The helicla flute that said helix core puts is evenly distributed with three.
Be provided with buffer spring between said pump barrel and the last valve seat.
Be provided with down buffer spring between said rotating cylinder and the following valve seat.
The utility model is provided with the drill bit that is driven by screw pair through the lower end at whole device, can in the pump drainage process at sand bucket, drive the drill bit rotation, makes the sand grains that hardens loose, thereby has improved the effect of dragging for sand efficient and dragging for the sand operation.

The specific embodiment
As shown in the figure, this spiral drilling type sand bucket includes and is used for the water out adapter 1 that is connected with the tubing string of transferring power, and water out adapter is provided with delivery port 2, and the water out adapter lower end is provided with valve seat 3 and last valve 4; Last valve seat lower end connects the pull bar 5 of hollow; Pull bar stretches in the pump barrel 6 of sealing; The pull bar lower end connects plunger 7; Plunger is upper and lower mobile in pump barrel under the drive of pull bar 5, and axial limiting can be carried out to the pull bar lower end in the pump barrel upper end, can drive pump barrel one the same moving when promptly moving on to the pump barrel upper end on the pull bar lower end; Pump barrel 6 lower ends connect cartridge 8, and the cartridge lower end is provided with down valve seat 9 and following valve 10; Following valve seat lower end is connected with the core retainer plate pull bar 11 of hollow, and core retainer plate pull bar lower end connects the spiral core retainer plate 12 of a hollow, and spiral core retainer plate outer wall is provided with helicla flute 13; Be with a rotatable rotary tube 14 in the periphery of spiral core retainer plate; The inwall of rotating cylinder is provided with the rotating dog 15 that is placed in the above-mentioned helicla flute 13 and distributes along helix; Rotating cylinder 14 forms screw pair with spiral core retainer plate 12 through rotating dog 15 and cooperating of helicla flute 13, and the lower end of rotating cylinder connects drill bit 16.Be provided with the key 17 and keyway 18 that cooperatively interact between pull bar 5 and the pump barrel 6, to prevent the relative pull bar rotation of pump barrel.Be provided with buffer spring 19 between pump barrel 6 and the last valve seat 3.Be provided with down buffer spring 20 between rotating cylinder 14 and the following valve seat 10.
The utility model course of work is:
During operation, drill bit 16 is pressed on the sand face, drives water out adapter 1, pull bar 5 and plunger 6 by workover rig through tubing string and moves upward, and last valve 4 is closed, and following valve 10 is opened, in sand and the cartridge 10 that water entering pump barrel 6 lower ends are connected.When pull bar moves upward to spacing place, upper end with respect to pump barrel 6; Then driving pump barrel 6, core retainer plate pull bar 11, spiral core retainer plate 12 continues to move upward; Have three-way helicla flute 13 on the spiral core retainer plate 12; Rotating dog 15 driven rotary tubes 14 through being three-way spiral begin rotation with drill bit 16, bore loose down-hole sand grains.When moving to the whole system after top dead center, workover rig drive tubing string begins to transfer tubing string; Core retainer plate pull bar 11, spiral core retainer plate 12 move downward, and drill bit 16 reverse rotation in sand is when spiral core retainer plate 12 moves to after bottom dead center; Plunger 6 beginnings move downward with respect to pump barrel 6; Following valve 10 is closed, and last valve 4 is opened, and water is discharged in the pit shaft through the delivery port 2 of water out adapter 1.Sand is accomplished the work of a circulation thus owing to than great, be deposited in the cartridge 10.
Because the effect of key 17 and keyway 18 can guarantee that pump barrel 6 and spiral core retainer plate 12 do not rotate, thereby guarantees the drill bit rotation.
