Abstract
The utility model relates to the file of connecting rod pieces, and in particular relates to a splicing rod which is used to replace a sucker rod to be matched with a heavy oil well, high viscosity, high torque or an assorted personnel computer (PC) pump for underground petroleum resource exploitation and also can be used as a drill pipe. According to the technical scheme, the splicing rod comprises a rod body and connectors at the two ends of the rod body, wherein each of the connectors at the two ends of the rod body is axially provided with a raised head, a groove is formed on one raised head, and the raised head with the groove and the raised head of the connector on the other end form the concave-convex spliced match. In order to satisfy the oil field production requirement, threads are prevented from losing effectiveness due to overlarge torque, through additionally arranging the raised heads for splicing, the splicing parts of the raised heads are used for playing a function of torsion resistance, so that the connection threads are effectively prevented from being deformed due to stress, and the thread gluing possibility is reduced.
Description
Technical field
The utility model relates to and connects the rod member field, is specially adapted to cooperate heavy oil wells, high viscosity, high moment of torsion or supporting PC pump to carry out the underground petroleum resource exploitation and uses alternative sucker rod, and can be used as the drilling rod use.
Background technology
Existing all kinds of of a great variety for solving the special type sucker rod that heavy oil wells, high viscosity, high moment of torsion and supporting PC pump designed on the market, it need rely on the decision of sucker rod own characteristic and be threaded.This type special type sucker rod because of the excessive thread failure that causes of moment of torsion in using, influences production operation mostly at present.
The utility model content
The purpose of the utility model is a kind of for what avoid screw thread to cause losing efficacy and propose because of moment of torsion is excessive, can satisfy the sucker rod connection request, can satisfy the shank of joint high-strength anti-torsion requirement again.
Its technical scheme comprises: the connector at the body of rod and body of rod two ends, and the joint at body of rod two ends is provided with plush copper vertically, and one of them plush copper is offered groove, constitutes concave-convex inserting with the plush copper of other end joint and cooperates.
Described groove comprises V-arrangement, U-shaped, trapezoidal or square, and corresponding with it other end plush copper adopts and the same shape of groove.
Two joints of the body of rod are equipped with external screw thread; Perhaps one of them joint is provided with tapped adapter sleeve, and another joint is provided with the external screw thread with the adapter sleeve screw-internal thread fit.
The utility model avoids screw thread to cause because of moment of torsion is excessive losing efficacy for reaching the field produces requirement, through setting up the grafting plush copper, relies on its part of pegging graft to bear antitorque function, effectively avoids the connecting thread stress deformation, and reducing thread gluing maybe.
Description of drawings
Fig. 1 is the front view of a kind of embodiment of the utility model.
Fig. 2 is vertical view or the upward view of Fig. 1.
Fig. 3 is a kind of vertical view of concrete connection status.
Among the figure: the 1st, the plush copper of band groove; The 2nd, joint also has external screw thread; The 3rd, the body of rod; The 4th, the plush copper of the other end; The 5th, adapter sleeve or title box cupling.Reference numeral in order to clearly demonstrate shank integral body is disassembled mark explanation, except splicing sleeve or claim the box cupling 5 other parts real be one.
The specific embodiment
With reference to Fig. 1 and 2, the joint 2 at the body of rod 3 two ends is provided with plush copper vertically, and one of them plush copper 1 is offered groove, constitutes concave-convex inserting with the plush copper 4 of other end joint and cooperates.
Described groove comprises V-arrangement, U-shaped, trapezoidal or square, and corresponding with it other end plush copper adopts and the same shape of groove.What provide among the figure is that v-depression cooperates.
With reference to accompanying drawing 3, two joints of the body of rod are equipped with external screw thread, implement to connect through independent adapter sleeve 5.
Also can one of them joint be provided with tapped adapter sleeve in the foregoing description, another joint is provided with the external screw thread with the adapter sleeve screw-internal thread fit.It is the structure that the body of rod itself has adapter sleeve.
For reach be threaded purpose and with the supporting use of the bodies of rod such as existing sucker rod; Screw thread design is considered strength factor, and As soon as possible Promising Policy API SPEC 11B " sucker rod, polished rod and lining, box cupling, weighted lever, polished rod clamp, seal box and oil pumping threeway standard " double thread detects requirement simultaneously.
This shank not only is used for sucker rod, can also substitute application such as drilling rod.
