Abstract
The utility model relates to the technical field of coiled tubing delivering perforations, in particular to a coiled tubing delivering perforation torsion release short joint. The coiled tubing delivering perforation torsion release short joint comprises an upper connection and a lower connection, wherein the upper connection is connected with the lower connection, the upper connection and the lower connection can rotate relatively by installing steel balls, an O-shaped ring is used to seal the upper connection and the lower connection, and the upper joint is provided with plug screws. The coiled tubing delivering perforation torsion release short joint achieves the purpose that a coiled tubing and a pipe string which is connected on the lower end of the coiled tubing can relatively and freely rotate, avoids the phenomenon that the coiled tubing is damaged because of bearing excessive torsion, and overcomes the defect that the coiled tubing is damaged because of bearing excessive torsion.
Description
Technical field:
The utility model relates to a kind of coiled tubing conveying gun perforation technical field, particularly a kind of coiled tubing conveying gun perforation moment of torsion release nipple.
Background technology:
In coiled tubing transmission perforation operation process, often run into the hole conditions such as high angle hole, horizontal well, will cause the pipe string twisting thereby pipe string is gone into the well with wall friction in the process, and torsion can be delivered to coiled tubing and makes it be subject to moment of torsion.If moment of torsion is crossed senior general and is directly damaged coiled tubing or cause fatigue failure.
The utility model content:
The technical problems to be solved in the utility model provides a kind of coiled tubing conveying gun perforation moment of torsion release nipple, and this device has realized that the pipe string that coiled tubing is connected with the lower end can rotate relatively freely, and it is excessive and damage to avoid coiled tubing to bear moment of torsion.Overcome existing coiled tubing and be subject to the excessive and deficiency damaged of moment of torsion.
Technical solution adopted in the utility model is: a kind of coiled tubing conveying gun perforation moment of torsion release nipple comprises top connection and lower contact; Top connection is connected with lower contact, can relatively rotate by steel ball is installed between top connection and the lower contact, seals by O type circle between top connection and the lower contact, and plug screw is installed in the top connection.
The beneficial effects of the utility model are: the utility model is owing to adopted the mode that steel ball is installed between top connection and lower contact, thereby have the function that pipe string that coiled tubing is connected with the lower end can rotate relatively freely, it is excessive and damage to avoid coiled tubing to bear moment of torsion.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of coiled tubing conveying gun perforation moment of torsion release nipple comprises top connection 1 and lower contact 5; Top connection 1 is connected with lower contact 5, can relatively rotate by steel ball 4 is installed between top connection 1 and the lower contact 5, seals by O type circle 2 between top connection 1 and the lower contact 5, and plug screw 3 is installed in the top connection 1.
When the utility model uses, when ending tool is subject to moment of torsion instantly, lower contact 5 will rotate, and drive simultaneously steel ball 4 and rotate, and top connection 1 then can not rotate.
Be understandable that, more than about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
