Technical field
The utility model relates to oil and gas development specific purpose tool fields, and in particular to a kind of slotting washing for drilling rod recycling of cementing the well
Cylinder.
Background technique
During oil and gas development, well cementation is an indispensable important link during being drilled well operations, it includes
Setting of casing and cementing.Cementing is the critical process after casing lower going-into-well, and effect is the annular space by casing and the borehole wall
Sealing is got up, and to insulate oil-gas-water layer, so that casing is become oil gas and is led to the channel in well.When cementing, cement is injected from drilling rod,
Subsequently into the gap between casing and the borehole wall；Therefore sometimes cement can enter annular space between drilling rod and casing, at this time certain
Section drilling rod can cannot propose in cement there is a situation where solid；Existing processing method is usually tripping in packaged milling tool, directly
The box cupling of drilling rod is destroyed to propose drilling rod, causes drilling rod to be damaged, or even sometimes pit shaft can be also destroyed.
Utility model content
The purpose of this utility model provides a kind of structure and is simple and convenient to operate aiming at defect of the existing technology
For cement the well drilling rod recycling slotting washing cylinder, can be realized in the case where not destroying drilling rod and completely take out drilling rod.
The technical solution of the utility model is:
A kind of slotting washing cylinder for drilling rod recycling of cementing the well, including cylinder, the cylinder are made of more pipe nipple interconnections
And inner cavity is interpenetrated, wherein the upper end of first pipe nipple is equipped with the top connection for connecting with sucker rod, the end root pipe nipple
Lower end is inclined opening structure；The connecting pin internal diameter of first pipe nipple in two pipe nipples of adjacent connection is greater than whole internal diameter, the
The connecting pin outer diameter of two pipe nipples is less than whole outer diameter, and the connecting pin of two pipe nipples passes through outside mating connect and compose
The uniform integral cylinder of diameter, internal diameter；Multiple through-holes, and first is distributed in spaced radial on the connecting pin of first pipe nipple
It is welded and fixed and is integrated by the through-hole after root pipe nipple and second pipe nipple are mating.
Further, the pipe nipple of interconnection is 2-3 root, and every length is 8-10 meters.
Further, the outer diameter of the pipe nipple is 114mm, wall thickness 4mm.
Further, the number of openings is 5-6.
Further, the material of the cylinder is g105.
Compared with prior art, the utility model structure is simple and convenient to operate, can not destroy substantially drilling rod and
The solid drilling rod complete extraction in well can be come out under the premise of pit shaft, to avoid the generation of second accident, and big
Operating cost is reduced greatly, improves the safety of construction.

Specific embodiment
Embodiment 1
Referring to Fig.1 shown in -5, a kind of slotting washing cylinder for drilling rod recycling of cementing the well, including cylinder 1, cylinder 1 are short by two
Section i.e. the first pipe nipple 11, the second pipe nipple 12 interconnect the integral cylinder that the inner cavity constituted is interpenetrated, wherein the first pipe nipple
11 upper end is equipped with the top connection 2 for connecting with sucker rod, and the lower end of the second pipe nipple 12 is inclined opening structure 3(pen tip shape)；The
Connecting pin (i.e. the expanding structure in the lower end 5) internal diameter of one pipe nipple 11 is greater than connecting pin (the i.e. upper end of whole internal diameter, second pipe nipple
6 undergauge structures) outer diameter is less than whole outer diameter, i.e., the connecting pin internal diameter of first pipe nipple in two pipe nipples of adjacent connection
It is identical as the connecting pin outer diameter basic size of second pipe nipple；And the connecting pin of two pipe nipples passes through outside mating connect and compose
The uniform integral cylinder of diameter, internal diameter (i.e. the outer diameter and inner diameter of cylinder is the same from top to bottom, is more convenient for constructing)；First
Multiple through-holes 7 are distributed in spaced radial on the connecting pin of pipe nipple 11, and by logical after 12 grafting of the first pipe nipple 11 and the second pipe nipple
Position one is welded and fixed in hole 7, i.e., the two is connected and fixed by the solder joint 4 that spot welding constitutes annular configuration in through-hole 7.
Embodiment 2
On the basis of 1 structure of embodiment, the utility model provides a kind of tool of slotting washing cylinder for drilling rod recycling of cementing the well
Body design scheme.It is 121-124mm for existing common casing inner diameter, the nominal outer diameter of drill pipe coupling is 105mm, drilling rod
Due to reusing abrasion for a long time, box cupling diameter is usually less than nominal outer diameter；Therefore consider drill rod abrasion, drill pipe coupling and set
Lateral distance between pipe only residue 8-10mm(121-105=16/2=8mm)；That is the slotting washing cylinder internal diameter that we design
It is greater than the outer diameter of drill pipe coupling, outer diameter is less than casing inner diameter；Therefore it for 114mm, wall thickness is the short of 4mm that we, which select outer diameter,
It saves (wall thickness of the connecting pin of the first pipe nipple and the second pipe nipple is respectively 2mm at this time), internal diameter 106mm；The length of pipe nipple is
Two of 10m, material select g105, and the length of pipe nipple is too long to will affect intensity, best with 20-30 meters；Through-hole and solder joint
Quantity is the 5-6 requirements that can meet bonding strength.It is strong that welding can both be met by the solder joint fixed design of annular distribution
The requirement of degree, while the outer diameter and inner diameter of cylinder will not be impacted.Such as due to conventional threaded connection scheme, although even
It connects conveniently, but for wall thickness only 4mm, if reprocessing internal and external threads, it is clear that increase difficulty of processing, and it is strong to influence connection
Degree；If will be directly fully welded after the port docking of two pipe nipples, it may just will affect the diameter of cylinder, cause diameter to increase, no
Convenient for entire tool G.I.H.
The course of work of the slotting washing cylinder of Examples 1 and 2 are as follows: insert washing cylinder by 2 jointed rod of top connection, pass through lower kelly bar
Cover its downlink in the outside of drilling rod to be extracted (drilling rod lived admittedly by cement).Then pass through the inclined opening structure (pen tip shape) of lower end
The solid cement outside drilling rod is destroyed, then can be come out drilling rod complete extraction to be extracted by other tools；In order to
It is destroyed convenient for cement, water can also be pumped into well by drilling rod, efficiency is abolished to improve cement by water circulation.
The utility model is not limited to above-mentioned embodiment, within the knowledge of those skilled in the art,
The present invention can also be realized without departing from the purpose of the present invention. Make a variety of changes, and the content after variation still falls within the utility model
Protection scope.
