Abstract
A kind of downhole tool dismounts positioner, including：Top-pushing mechanism（1）, clamp system（2）, base（3）.The downhole tool dismounts the base of positioner（3）For elongated stool shape, right-hand member top is provided with pressure clamp shape clamp system（2）, base（3）Left upper part be provided with fixed block（3.1）, fixed block（3.1）Provided with through hole, the left side of through hole is provided with groove, top-pushing mechanism（1）Spigot nut（1.2）The group of bottom（1.2.1）, screw rod（1.2.2）Fixed block is inserted respectively（3.1）Groove and through hole, top-pushing mechanism（1）It is fixed.The utility model is applied to the assembling of oil field well instrument, maintenance, especially gland only needs to 3min under the dismounting type packers of Y111 114, gland only needs 2 min under the dismounting type packers of Y111 150, solve the problem of gland efficiency is low, labor intensity is big, security is poor under the dismounting positioning of Y111 types packer, improve remediation efficiency, safe operation, reduces the labor intensity of workman, strengthens operation supportability.
Description
Technical field
The utility model is related to the assembling of oil field well instrument, maintenance aid, and specifically a kind of downhole tool is torn open
Fill positioner.
Background technology
Type packer is one of conventional downhole tool, mainly including two kinds of packers of Y111-150, Y111-114.The two is tied
Structure is essentially identical, wherein in 3 sealing rings in gland under changing the type packer, it is necessary to by central tube from lower gland
Exit, through measuring and calculating, the frictional force of gland is 27.342N under Y111-114, and Y111-150 lower gland frictional force is 162.288N,
Workpiece and central tube frictional resistance are big, due to no specific purpose tool, and generally move workpiece by worker during dismounting pounds on chock
Impact, heavier-weight, labor intensity is larger, needs also exist for carrying out similar operation during assembling.Especially run into silt particle attachment
During instrument, operating personnel are more laborious, further, since workpiece impact is big, chock occurs being smashed or being pounded inclined phenomenon sometimes,
Injury operating personnel are easily caused, there is potential safety hazard.
The content of the invention
The purpose of this utility model dismounts positioner aiming at above-mentioned weak point there is provided a kind of downhole tool.
The purpose of this utility model is realized by following technical proposals:
The utility model includes：Top-pushing mechanism, pressure clamp, base.The base of downhole tool dismounting positioner is
Parallel chord truss structure, right-hand member top is provided with pressure clamp, and the left upper part of base is provided with fixed block, and fixed block is provided with through hole, through hole
Left side be provided with groove, group, the screw rod of the spigot nut bottom of top-pushing mechanism insert the groove and through hole of fixed block respectively,
Top-pushing mechanism is fixed.
The left end of the leading screw of top-pushing mechanism in above-mentioned downhole tool dismounting positioner joins with handle in T-shape structure
Connect, leading screw is threadedly coupled with spigot nut through the left end of leading screw is sequentially provided with thrust bearing, pushing tow head.
The beneficial effects of the utility model are：Suitable for the assembling of oil field well instrument, maintenance, Y111-114 types are especially dismantled
Gland, which only needs to gland under 3min, dismounting Y111-150 type packers, under packer only needs 2 min, solves the packing of Y111 types
The problem of lower gland efficiency of device dismounting positioning is low, labor intensity is big, security is poor, improves remediation efficiency, and safe operation is reduced
The labor intensity of workman, strengthens operation supportability.
Brief description of the drawings
Fig. 1-the utility model main view broken section structural representation
In figure, 1. handles, 1.1 leading screws, 1.2 spigot nuts, 1.2.1. groups, 1.2.2. screw rods, 1.3, thrust axis
Hold, 1.4, pushing tow heads；2. pressure clamp, 3. bases, 3.1. fixed blocks.
Embodiment
Below in conjunction with the accompanying drawings, the utility model will be further described：
As shown in figure 1, downhole tool dismounting positioner is made up of top-pushing mechanism 1, pressure clamp 2, base 3.The underground
The base 3 of instrument dismounting positioner is parallel chord truss structure, and right-hand member top is provided with pressure clamp 2, and the left upper part of base 3 is provided with
Fixed block 3.1, fixed block 3.1 is provided with through hole, and the left side of through hole is provided with groove, the shelves of the bottom of spigot nut 1.2 of top-pushing mechanism 1
Sub- 1.2.1, screw rod 1.2.2 insert the groove and through hole of fixed block 3.1 respectively, and top-pushing mechanism 1 is fixed.The top-pushing mechanism 1
The left end of leading screw 1.1 couple with handle 1.0 in T-shape structure, leading screw 1.1 is threadedly coupled through leading screw with spigot nut 1.2
1.1 left end is sequentially provided with thrust bearing 1.3, pushing tow first 1.4.Pressed from both sides in use, Y111 type packers are placed on pressure clamp 2
Tightly, handle 1.0 is rotated clockwise, drives leading screw 1.1 to move right, pushing tow first 1.4 promotes packer, and lower gland is unloaded, reached
To the purpose of quick-replaceable sealing ring.
