Abstract
The utility model relates to oil and gas development sucker rods, specifically, being related to a kind of steel wire sucker rod.The connector at wirerope body of rod both ends is crimped on including the wirerope body of rod and using compression joint technique, the connector is disposed with spanner side's section that thread segment, the stress compensating groove of annular, external screw thread close shoulder section and annular groove-shaped from outside to inside, the thread segment is equipped with external screw thread, and outer end is equipped with the screw thread chamfering of taper.The utility model uses the stronger wirerope body of rod of flexibility, and not only the manufacturing cycle is short, at low cost, transport convenience, and oil recovery piston effect is small, and eccentric wear is low, is conducive to improve workover treatment efficiency, ensures the normal production in oil field.
Description
Technical field
The utility model relates to oil and gas development sucker rods, specifically, being related to a kind of steel wire sucker rod.
Background technique
Currently, oilfield producing well is largely using there is bar oil recovery, sucker rod substantially uses the steel body of rod, not only cost
It is high, not readily transportable, moreover, its hardness is high, oil recovery piston effect is big, eccentric wear is big, it can also reduce workover operations efficiency, shadow
Ring the normal production in oil field.
Utility model content
The purpose of the utility model is to provide a kind of steel wire sucker rods, to solve above-mentioned technical problem.
To achieve the goals above, the utility model uses following technical scheme:
A kind of steel wire sucker rod, it is characterised in that: be crimped on wirerope including the wirerope body of rod and using compression joint technique
The connector at body of rod both ends, the connector are disposed with thread segment, the stress compensating groove of annular, external screw thread from outside to inside and close
The spanner side of shoulder section and annular groove-shaped section, the thread segment are equipped with external screw thread, and outer end is equipped with the screw thread chamfering of taper.
The utility model has the advantages that the utility model uses the stronger wirerope body of rod of flexibility compared with pumping rod made by steel, not only make
It is short to make the period, at low cost, transport convenience, and oil recovery piston effect is small, and eccentric wear is low, is conducive to improve workover treatment efficiency, protect
Hinder the normal production in oil field.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig.1, steel wire sucker rod described in the utility model, including the wirerope body of rod 1 and use compression joint technique pressure
The connector at 1 both ends of the wirerope body of rod is connect, the connector is disposed with thread segment 5 from outside to inside, the stress of annular unloads
Lotus slot 4, external screw thread close spanner side's section 2 of shoulder section 3 and annular groove-shaped, and the thread segment 5 is equipped with external screw thread, and outer end is equipped with cone
The screw thread chamfering of shape.
The above is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all benefits
The equivalent structure made by the utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain, similarly within the scope of patent protection of the utility model.
