Description
Technical field
The present invention relates to a kind of drilling tool, more particularly to a kind of bottomhole tool-face anchor and method.
Background technology
Deep-well, extended reach well orientation work progress in, use screw rod（Or turbine）Slide-and-guide drilling technology is crept into,
When final stage adjusts track, the problem of tool-face is difficult to control is frequently present of.With the increase of drilling tool length, drilling tool it is whole
Body flexibility also increases therewith, thus ground is also greatly increased in face of the control difficulty of downhole motor tool-face, hole deviation is big, horizontal position
It moves in big wellbore, the frictional resistance and friction torque of the borehole wall and drilling tool are big.This has been resulted in practice of construction, can with it is substantial amounts of when
Between go pendulum tool-face, often by tool-face placement one think suitable position when, as long as（Turn on pump cycles）Drill bit one contacts shaft bottom,
Tool-face is almost to be inverted without restrictions, at random to time, even can invert a few to returning sometimes, which results in right before pressurization
The size of untwisting angle is unable to estimate at all.Since the frictional resistance of drilling tool and the borehole wall is not known yet, the reaction torque in drill bit and shaft bottom from
Drilling rod is uploaded to be come less than ground, is also no at all locked turntable and is caught the reaction torque come to resist shaft bottom.Only accidental chance work
Very suitable position is placed in tool face, and when reaction torque is also just equal with friction moment could stablize at the desired position（Device
Angle is suitable）.So have no regularly, to only rely on accidental chance and ajust tool-face, substantial amounts of drilling time has both been wasted, to construction
Bring many difficulties.
The tool-face anchor newly developed then solves the practical problem in this production, using after this instrument, is not opening
Pump pressurization before tool-face be placed on where, the palm after turn on pump because of tool-face anchor is just gripped on the borehole wall, drilling tool after pressurization
The reaction torque of generation is just all consumed on the borehole wall, and the untwisting angle very little so generated can put instrument through overtesting
This angle (or even can be ignored) is added during face.Since the effect of " What You See Is What You Get " of tool-face anchor causes
Tool-face is put in deep-well, extended reach well becomes abnormal free and relaxed, has reached real in solution deep-well, extended reach well drilling process
The purpose of border problem, it may have good economic benefit.
The content of the invention

Specific embodiment
The preferred embodiment of the present invention is illustrated below in conjunction with attached drawing, it should be understood that preferred reality described herein
It applies example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
A kind of bottomhole tool-face anchor that the present invention mentions, technical solution are：Including body 1, loose-leaf 2, hard
Matter carbide button 3, piston 6, the body 1 are hollow cylindrical pipe nipple, are equipped with female thread 13 on the top of body 1, lower end is equipped with
Pin thread 14 is equipped with equally distributed three loose-leaves 2 in the middle part outer wall of body 1, and three loose-leaves are fixed counterclockwise,
Three rows inclined hard-metal insert 3 counterclockwise is inlaid on the movable end outer wall of each loose-leaf 2, each loose-leaf 2 is interior with body
Columnar piston hole 12 is respectively equipped between chamber, and connecting hole is equipped between 1 inner cavity of piston hole 12 and body, in piston hole 12
Piston 6 is inside installed, piston 6 is displaced outwardly under the action of 1 chamber pressure of body, the activity of the piston after movement and loose-leaf 2
Inner wall contact is held, and loose-leaf 2 is made to contact the hard-metal insert 3 on movable end outer wall in fact with the borehole wall around fixing end rotary expansion
Now it is anchored.
Wherein, the fixing end of loose-leaf 2 is fixed on by slips 4 and screw 5 on body 1, in the one side of the movable end of loose-leaf 2
Body 1 be equipped with set screw 10, and the diameter of the head of screw of set screw is more than the outer diameter of cylindrical fixing end, and
Head of screw and a diameter of arcuate structure of the screw body of rod, in addition fixing end be mounted on the one side of arcuate structure, limited by head of screw
The rotation angle of the fixing end of loose-leaf 2 processed, and then limit the maximum opening angle of movable end.
It is inlayed in addition, hard-metal insert 3 is tilted on loose-leaf 2 by direction counterclockwise, tilts the effect inlayed counterclockwise
It is that the tool-face anchor can be rotated clockwise with drill string, and when drill string inverts, the hard-metal insert meeting wedging borehole wall will be anti-twisted
Square is disappeared on the borehole wall, the anchoring in implementation tool face.
In addition, the outside of the piston 6 is equipped with piston groove, piston ring 11 is embedded in piston groove, is opened at the middle part of piston 6
Equipped with O-ring seal mounting groove, O-ring seal 7 and O-ring seal baffle ring 8 are installed in O-ring seal mounting groove, in work

O-ring seal 7 and O-ring seal baffle ring 8 are installed, the sealing of piston is strengthened in the setting for also having y-type seal ring 9 in mounting groove
Effect.
It should be noted that：The internal diameter of connecting hole is less than the internal diameter of piston hole 12, so can be instantaneous by the pressure of inner cavity
Amplification, increases the promotion effect to piston.
In addition, loose-leaf 2 is the arcuate structure of L-shaped, and three loose-leaves are fixed counterclockwise；Wherein, the fixation of loose-leaf
It holds as cylindrical structural, fixed effect can be improved, and in fixing end insertion body outer wall, movable end is made to be easy to around fixing end
Rotation in addition, set screw 10 is arranged close on the body of fixing end, limits the maximum opening angle of the movable end of loose-leaf 2.
In addition, the height of fixing end is more than the height of movable end, this is because fixing end needs to consolidate by slips and screw
Fixed, longer fixing end also improves fixing intensity, and fixing end is avoided to deviate from out of body；In addition, entire loose-leaf is when shrinking,
It is to be hidden in the groove of body outer wall, when being released by piston, is stretched out out of body groove.
The application method for the bottomhole tool-face anchor that the present invention mentions, including procedure below：
During wellbore construction, using sliding type directional drilling, tool-face tool face angle is determined before drilling, when turn on pump cycles,
Bottomhole tool-face anchor G.I.H can make drilling tool generate pressure drop, and then make the body of bottomhole tool-face anchor
