Description
Technical field
The present invention relates to a kind of oil field downhole tool more particularly to a kind of suspension arrangements for sucker rod.
Background technique
As the development that deepens continuously of work is adopted in gas injection three, need gas injection to supplement stratum energy after Dynamical characteristic energy attenuation；
It needs to implement gas injection technology after rising by sucker rod currently, insert pump or suction pump machine take out tubing string gas injection, plays sucker rod and need
Upper workover rig and its ancillary equipment, well workover period are about 3 days；Machine is needed to take out after gas injection, it will lower oil pumping again when production
Bar, increasing the well workover period is about 3 days；Thus production efficiency is largely effected on, while also increasing the expense of well workover twice.
In addition, existing Dlagnosis of Sucker Rod Pumping Well since wellhead equipment pressure-bearing is lower, influences partial high pressure positive injection operation；Into
It when the operations such as row water filling, gas injection, oil pipe de-plugging, needs to employ tubing string in workover rig replacement well head or well, is required with meeting injection,
A large amount of human and material resources can thus be expended.At the same time, in order to reduce the corrosion in gas injection process to casing, oil pipe need to be carried out
Gas injection technology.
Thus, it is desirable to design a kind of sucker rod suspension device, gas injection technology is completed in the case where not playing roofbolt to realize,
To reduce actuating oil-pumping unit increased workover cost and avoid reduce Petroleum Production efficiency.
Summary of the invention
To solve above-mentioned the problems of the prior art, the present invention provides a kind of sucker rod suspension devices.
To achieve the above object, the specific technical solution of sucker rod suspension device of the invention is as follows:
A kind of sucker rod suspension device, including tubular suspension ontology, the two sides for hanging ontology are connected with surface tool
Have an externally threaded interconnecting piece, the interconnecting piece is used for connecting with pumping rod, hang be provided on ontology at least one axially through
The groove for hanging ontology, when suspension ontology is seated in tubing hanger, the groove can form the channel for gas injection.
Further, the groove is arranged along the edge of suspension ontology, and has on the curved wall surface of suspension ontology
Opening.
Further, the groove is rectangular recess.
Further, the quantity of the groove is 3, and setting evenly spaced from one another.
Further, it is formed with chamfering on the side wall of the suspension ontology, and the chamfering is 45 degree.
Further, it hangs between ontology and the interconnecting piece of side and is connected with hanger bar, be formed with flange in hanger bar.
Further, the junction hung between ontology and interconnecting piece or hanger bar is formed with fillet.
Sucker rod suspension device of the invention completes gas injection technology in the case where can not may be implemented in roofbolt, is removed with reducing
It sucker rod and increased workover cost and avoids reducing Petroleum Production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of sucker rod suspension device according to the present invention；
Fig. 2 is the side view of sucker rod suspension device in Fig. 1.
Specific embodiment
It is with reference to the accompanying drawing, outstanding to sucker rod of the invention in order to be best understood from the purpose of the present invention, structure and function
Hang device is described in further detail.
As shown in Figs. 1-2, sucker rod suspension device of the invention includes tubular suspension ontology 3, suspension ontology 3
Two sides are connected with interconnecting piece 2, and the surface of interconnecting piece 2 has external screw thread 21, and the interconnecting piece 2 is used for connecting with pumping rod, and suspension is originally
At least one is provided on body 3 axially through the groove 4 of suspension ontology 3.Before gas injection construction, acts sucker rod, will pump
Bar suspension arrangement is connected with sucker rod in well, and sucker rod suspension device is sat in tubing hanger, realizes sucker rod hanging.As a result,
When suspension ontology 3 is seated in tubing hanger, the groove 4 can form the channel for gas injection, to realize in the feelings for not playing roofbolt
Gas injection technology is completed under condition.
Specifically, the groove 4 hangs ontology in cylindrical along the edge setting namely the setting of groove 4 of suspension ontology 3
On 3 curved wall, and there is opening on the curved wall surface of suspension ontology (3).The groove 4 is preferably that rectangle is recessed
Slot, the quantity of groove 4 is preferably 3, and setting evenly spaced from one another.
Further, chamfering 5 is formed in the one side wall of the suspension ontology 3, chamfering 5 for example can be 45 degree.It is described fall
Angle 5 is preferably disposed on the side (such as downside) of suspension ontology 3, can also be into facilitate suspension ontology 3 to be seated in tubing hanger downwards
One step polishes smooth chamfering 5.
It is connected with hanger bar 1 between suspension ontology 3 and the interconnecting piece 2 of side, flange 6 is formed in hanger bar 1, such as Fig. 1
Shown, flange 6 is arranged in hanger bar 1 and far from suspension ontology 3.In addition, as preferred embodiment, suspension ontology 3 with
Junction between interconnecting piece 2 or hanger bar 1 is formed with fillet 7.
It is taken out in work progress hanging, fill to buckling out sucker rod hanging with the sucker rod of the female box cupling of band or internal screw thread
It sets；If the screw thread on sucker rod suspension device top is damaged because of gas injection seriously corroded, can not be filled to sucker rod hanging is buckled out
When setting, sucker rod suspension device can be proposed by the method for disassembly flange, polishing bar elevator, take out construction hang.
The present invention is further described by specific embodiment above, it should be understood that, here specifically
Description, should not be construed as the restriction for the essence of the present invention with range, and one of ordinary skilled in the art is reading this explanation
The various modifications made after book to above-described embodiment belong to the range that the present invention is protected.
