The invention discloses a kind of sucker rod suspension device, this sucker rod suspension device includes tubular suspension body, the both sides connection hanging body has surface to have externally threaded connecting portion, described connecting portion is used for connecting with pumping rod, hang and be provided with at least one on body axially through the groove hanging body, when hanging body and being seated in tubing hanger, described groove can form the passage for gas injection.The sucker rod suspension device of the present invention completes gas injection technology in the case of can not may be implemented in roofbolt, the workover cost increased to reduce actuating oil-pumping unit and avoid reduce Petroleum Production efficiency.
Description
Technical field
The present invention relates to a kind of oil field downhole tool, particularly relate to a kind of suspension arrangement for sucker rod.
Background technology
Carry out along with deepening continuously of work is adopted in gas injection three, after Dynamical characteristic energy attenuation, need gas injection with supplementary stratum energy；
At present, enforcement gas injection technology after tubing string gas injection needs to trip out sucker rod taken out by insert pump or suction pump machine, and playing sucker rod needs
Upper workover rig and auxiliary equipment thereof, its well workover cycle is about 3 days；Machine is needed to take out after gas injection, will lower oil pumping again during production
Bar, increase the well workover cycle be about 3 days；Thus largely effect on production efficiency, too increase the expense of twice well workover simultaneously.
Additionally, existing Dlagnosis of Sucker Rod Pumping Well is relatively low due to wellhead equipment pressure-bearing, affects partial high pressure and just noting operation；Entering
During the operations such as row water filling, gas injection, oil pipe de-plugging, need to employ workover rig and change tubing string in well head or well, with satisfied injection requirement,
Thus can expend a large amount of human and material resources.Meanwhile, in order to reduce in gas injection process the corrosion to sleeve pipe, oil pipe need to be carried out
Gas injection technology.
Thus, it is desirable to a kind of sucker rod suspension device of design, to realize completing gas injection technology in the case of not playing roofbolt,
To reduce actuating oil-pumping unit and the workover cost that increases and avoid reducing Petroleum Production efficiency.
Summary of the invention
For solving above-mentioned the problems of the prior art, the invention provides a kind of sucker rod suspension device.
For achieving the above object, the concrete technical scheme of the sucker rod suspension device of the present invention is as follows:
A kind of sucker rod suspension device, including tubular suspension body, the both sides connection hanging body has surface to have
Having externally threaded connecting portion, described connecting portion is used for connecting with pumping rod, hang be provided with on body at least one axially through
Hanging the groove of body, when hanging body and being seated in tubing hanger, described groove can form the passage for gas injection.
Further, described groove is arranged along the edge hanging body, and has on the curved wall surface hanging body
Opening.
Further, described groove is rectangular recess.
Further, the quantity of described groove is 3, and setting evenly spaced from one another.
Further, the sidewall of described suspension body is formed with chamfering, and described chamfering is 45 degree.
Further, hanging to be connected between body and the connecting portion of side has hanger bar, and hanger bar is formed flange.
Further, the junction hung between body and connecting portion or hanger bar is formed with fillet.
The sucker rod suspension device of the present invention completes gas injection technology in the case of can not may be implemented in roofbolt, removes to reduce
Sucker rod and the workover cost that increases and avoid reducing Petroleum Production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sucker rod suspension device according to the present invention；
Fig. 2 is the side view of sucker rod suspension device in Fig. 1.
Detailed description of the invention
In order to be best understood from the purpose of the present invention, structure and function, below in conjunction with the accompanying drawings, the sucker rod of the present invention is hanged
Hang device is described in further detail.
As shown in Figure 1-2, the sucker rod suspension device of the present invention includes tubular suspension body 3, hangs body 3
Both sides connect has connecting portion 2, the surface of connecting portion 2 to have external screw thread 21, and described connecting portion 2, for connecting with pumping rod, hangs this
At least one it is provided with axially through the groove 4 hanging body 3 on body 3.Before gas injection is constructed, trip out sucker rod, will oil pumping
Bar suspension arrangement is connected with sucker rod in well, is sat on by sucker rod suspension device in tubing hanger, it is achieved sucker rod hanging.Thus,
When hanging body 3 and being seated in tubing hanger, described groove 4 can form the passage for gas injection, to realize in the feelings not playing roofbolt
Gas injection technology is completed under condition.
Specifically, described groove 4 is arranged along the edge hanging body 3, namely groove 4 is arranged on cylindrical and hangs body
On the curved wall of 3, and on the curved wall surface hanging body (3), there is opening.Described groove 4 is preferably rectangular recessed
Groove, the quantity of groove 4 is preferably 3, and setting evenly spaced from one another.
Further, a sidewall of described suspension body 3 being formed with chamfering 5, chamfering 5 such as can be 45 degree.Described fall
Angle 5 is preferably disposed on the side (such as downside) hanging body 3, to facilitate suspension body 3 to be seated in downwards in tubing hanger, it is possible to enter
Chamfering 5 is polished smooth by one step.
Hang to be connected between body 3 and the connecting portion 2 of side and have hanger bar 1, hanger bar 1 is formed with flange 6, such as Fig. 1
Shown in, flange 6 is arranged in hanger bar 1 and away from hanging body 3.Additionally, as preferred embodiment, hang body 3 with
Junction between connecting portion 2 or hanger bar 1 is formed with fillet 7.
In extension takes out work progress, carry out make-up with the sucker rod of band mother's box cupling or female thread and trip out sucker rod hanging dress
Put；If the screw thread on sucker rod suspension device top damages because of gas injection seriously corroded, it is impossible to make-up trips out sucker rod hanging dress
When putting, sucker rod suspension device can be proposed by the method for dismounting flange, polishing bar elevator, take out construction carrying out extension.
By specific embodiment the present invention done above further describe it should be understood that, the most concrete
Describing, should not be construed as the restriction to the spirit and scope of the invention, one of ordinary skilled in the art is reading this explanation
The various amendments after book made above-described embodiment, broadly fall into the scope that the present invention is protected.
