Abstract
The utility model relates to a novel sucker rod in the technical field of oil field oil production equipments, which comprises a rod body, wherein a threaded hole with internal threads is formed at one end of the rod body, and at least one exhaling hole for allowing the bottom of the threaded hole to be connected with the space on the outer side of the rod body is formed at the bottom of the threaded hole. During the connection process of the rod body, the dead oil, thread compound and gas sealed in the threaded hole flows out from the exhaling hole under the action of extrusion of the rod body, so that the sucker rod is easily buckled and easily tightened between the internal threads and the external threads, and avoids the possible looseness during the use; and compared with the prior art, the novel sucker rod has the advantages of simple structure, convenience in processing and reliability in use.
Description
Technical field
The utility model relates to a kind of oil field oil recovery apparatus, particularly a kind of sucker rod.
Background technology
Sucker rod of the prior art, comprise the body of rod, one end of the body of rod is provided with internal thread, the other end is provided with external screw thread, can a plurality of bodies of rod continuous in proper order, in the sucker rod connection procedure, when the female end of the body of rod is connected with the male end of other bodies of rod,, when tightening, has anti-top power owing to have dead oil, dope and gas in the screwed hole, cause cannot fasten, in normal oil recovery process, the pumping rod disengaging accident takes place easily, need operation again, influence the output of individual well, increased cost for oil production.
The utility model content
For overcoming the defective of prior art, the utility model provides a kind of novel sucker rod, makes sucker rod easy to connect, avoids loosening.
The purpose of this utility model is achieved in that a kind of novel sucker rod, comprises the body of rod, and the body of rod one end is provided with the screwed hole that has internal thread, and described screwed hole bottom is provided with the exhaling hole that at least one connects screwed hole bottom and body of rod outer space.
In the process that the body of rod connects, seal dead oil, dope and gas in screwed hole up for safekeeping, under the extruding of the body of rod, from exhaling hole, flow out, be easy to button, tighten easily between internal thread and the external screw thread, that has avoided may occurring in the use becomes flexible; Compared with prior art, the utility model is simple in structure, and is easy to process, uses reliable.
Convenient for guaranteeing that dead oil, dope and gas flow out, described exhaling hole radially extends to body of rod side surface.Because radial distance is the shortest, can discharge dead oil, dope and gas easily.
As further improvement of the utility model, described exhaling hole is a circular hole.Circular hole is easy to process, can not cause stress to concentrate simultaneously, can guarantee the intensity of the body of rod.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 body of rod, 2 screwed holes, 3 exhaling holes.
The specific embodiment
As shown in the figure, be a kind of novel sucker rod, comprise the body of rod 1, one end of the body of rod 1 is provided with the screwed hole 2 that has internal thread, the bottom of screwed hole 2 is provided with an exhaling hole 3 that screwed hole bottom and body of rod outer space are connected, exhaling hole 3 radially extends to the side surface of the body of rod 1, and this exhaling hole 3 is a circular hole.
The utility model is not limited to the foregoing description, and described exhaling hole can have more than one a plurality of, and exhaling hole also is not limited to circular hole, also can be shapes such as elliptical aperture, groove.
