Specific implementation mode
The utility model is described further below in conjunction with attached drawing：
A kind of screw bolt well free suspension anchoring device, including telescopic rod 1,1 upper end connected pipes of telescopic rod, telescopic rod 1
As oil pipe column is lowered into screw bolt well free suspension anchoring string, since telescopic rod 1 is in screw bolt well free suspension anchor
It is in free suspension state in fixed tube column, so not needing kill-job in job execution process blowout prevention, oil pipe column will not flexural deformation
Also eccentric wear would not occur, 1 upper and lower part of telescopic rod is evenly equipped with through-hole, and 1 lower end of telescopic rod connects cone 2, cone 2
Top is equipped with cone shoulder 14, and 1 top of telescopic rod is externally provided with upper exterior tube 3, one group of bar shaped is correspondingly provided in 3 inner wall axial direction of upper exterior tube
Slot 4,1 top of telescopic rod are fixed with slide plate 5, and the left and right sides of slide plate 5 is located in bar-shaped trough 4, and slide plate 5 is in bar-shaped trough 4
It can move up and down, but cannot rotate, and then ensure that telescopic rod 1 and oil pipe column do not rotate, achieve the purpose that anti-rotation,
3 lower end of upper exterior tube connects packer, connects packer lower end connection anchoring device, screw bolt well free suspension anchoring string, which is sent to, to be set
Realize that packer setting, anchoring device are anchored after giving up after meter set, anchoring device lower end connects screen casing 6,6 lower end of screen casing
Lower outer pipe 7 is connected, 7 inner wall of lower outer pipe is equipped with outer tube shoulder 9 and outer tube annular groove 10, sliding sleeve 8, sliding sleeve 8 are equipped in lower outer pipe 7
It can slide up and down, for blocking or opening the channel of screen casing 6 and screw bolt well free suspension anchoring string inner cavity, under sliding sleeve 8
Portion's even partition is in strip swollen pawl 11, and 11 lower section of swollen pawl is equipped with shoulder 12, and 11 lower end of swollen pawl is equipped with boss 13,7 lower end of lower outer pipe
It is connected with box cupling, oil pipe and silk plug.
In order to make the slide plate 5 on telescopic rod 1 smoothly enter in one group of bar-shaped trough 4 on upper exterior tube 3, on upper exterior tube 3
End face is jagged and is inclined-plane, plays the role of guide shoe and be more advantageous to prevent oil pipe column from inverting.
When in use, telescopic rod 1 is lowered into screw bolt well free suspension anchoring string inner cavity, slide plate 5 with oil pipe column
It enters in one on upper exterior tube 3 group of bar-shaped trough 4, sliding sleeve 8 carries out sealed condition to screen casing 6, with the downlink of telescopic rod 1, cone
The cone shoulder 14 on 2 top of body touches the boss 13 of 11 lower end of swollen pawl, and pushes 8 downlink of swollen pawl 11 and sliding sleeve, waits for swollen pawl 11
When the boss 13 of lower end goes downwards to the position of the outer tube annular groove 10 of 7 inner wall of lower outer pipe, under the action of reducing under swollen pawl 11
The boss 13 at end enters in outer tube annular groove 10, and cone 2 passes through, and screen casing 6 is managed with the anchoring of screw bolt well free suspension at this time
Column inner cavity is communicated in production status.When workover treatment, oil pipe is above carried, the uplink therewith of telescopic rod 1, during 1 uplink of telescopic rod,
The upper surface of cone 2 and 12 phase card of shoulder simultaneously take 8 uplink of sliding sleeve to, when shoulder 12 goes upward to the position of outer tube shoulder 9, shoulder
12 are stuck on outer tube shoulder 9, and the internal diameter of sliding sleeve 8 becomes larger at this time, and telescopic rod 1 is extracted out, and sliding sleeve 8 carries out sealed condition to screen casing 6 and reaches
To the purpose of blowout prevention.
