Hole-drawing device 1 still in work, has ensured that sleeve pipe enters and shaft bottom cementing quality under smooth.Band grout cures are that available drill bit pushes can
Weir 407 is bored, rotary shaft 301 is locked, the now ejection of retaining ring 404 annular groove, locking ring 402 cannot be return.Rotary shaft 301 is locked
Afterwards, spud in and bore except the bored hole-drawing device that can be bored in weir 407, turbine 201 and sleeve pipe hole-drawing device 1 leads footwear 104, continue to get out next step
New well.
The tubing string of the present embodiment can solve to enter due to the problem that is hampered that pit shaft undergauge, step are produced under oil drilling sleeve pipe,
The characteristics of with time-consuming short, efficiency high, burst accident can be reduced, reduce marine, land drillng operation totle drilling cost, and solid
The well cement injection stage, by tubing string bottom tool (including sleeve pipe hole-drawing device 1, vortex rotate pipe nipple 2, rotary dynamic seal pipe nipple
3) rotation, reduces and eliminates the microbubble in sleeve bottom cement mortar, cement mortar is evenly distributed, and is favorably improved set ttom of pipe
The cementing quality in portion.
Embodiment 2
As shown in Fig. 1 (b), present embodiment discloses a kind of construction operation tubing string for being applied to petroleum gas engineering, tool
Body is to be applied to the tubing string that acidizing treatment is increased production in oil formation improvement, and mainly rotating pipe nipple 2, rotation by acid solution injector 6, vortex moves close
Envelope pipe nipple 3 and oil connection 7 are constituted.
The concrete structure that vortex rotates pipe nipple 2 is same as Example 1, and here is omitted, and it differs only in turbine 201
The acidproof cast steel of material selection.The concrete structure of rotary dynamic seal pipe nipple 3 is same as Example 1, and here is omitted.
Vortex is rotated the upper end of shell 202 of pipe nipple 2 and is connected with pipe screw thread with the lower end of rotary shaft 301 of rotary dynamic seal pipe nipple 3
