Abstract
The utility model relates to the technical field of coiled tubing drilling, in particular to a non-rotating joint for coiled tubing drilling. The upper end of an upper non-rotating joint of a tool is provided with a drill pipe female thread, and the lower end of the upper non-rotating joint is provided with a drill pipe male thread. The tail end of the drill pipe male thread of the upper non-rotating joint is in the shape of a round tube which is evenly provided with splines on the periphery. A lower non-rotating joint comprises an upper joint, a central tube, a rotor and a lower joint. The upper joint is connected with the rotor in a threaded manner. The upper end of the upper joint is provided with a drill pipe female thread. The outer wall of the upper joint is provided with two symmetrical round holes. The central tube is connected with the lower joint in a threaded manner. The central tube is capable of rotating with respect to the upper joint and the rotor. The inner wall of the upper end of the central tube is provided with spline grooves matching with the splines of the upper non-rotating joint. A coiled tube and a special downhole tool can be serially connected with each other at a wellhead with no need of rotating. The defect that serially connecting the coiled tube and the special downhole tool to the wellhead needs rotating is overcome.
Description
Technical field:
The utility model relates to a kind of continuous-tube drilling technology field, particularly the non-rotating joint of a kind of continuous-tube drilling well.
Background technology:
In the continuous-tube drilling process, when well head fastening means pipe string, the drill string that the continuous-tube below connects is all long, the longlyest can reach about 40m, so long tool pipe string is when well head connects into well, according to the drill-well operation rules, do not allow to rotate, and continuous-tube also is non-rotatable, therefore need a kind of instrument of design, this instrument can play the effect that connects continuous-tube and drilling tool pipe string on the one hand, can guarantee again on the other hand rotation button in the situation of not rotating continuous-tube and drilling tool.
The utility model content:
The technical problems to be solved in the utility model provides the non-rotating joint of a kind of continuous-tube drilling well, and this instrument has realized that coiled tubing need not to rotate the purpose that can be connected with down-hole special tool string at well head.Overcome the deficiency that existing coiled tubing and down-hole special tool string need to rotate when well head is connected.
Technical solution adopted in the utility model is: the non-rotating joint of a kind of continuous-tube drilling well comprises non-rotating joint and lower non-rotating joint; Upper non-rotating upper end of joint is designed with the drilling rod box, and the lower end is designed to the drilling rod pin thread, and the drilling rod pin thread tip designs of upper non-rotating joint becomes circular tube shaped and pipe is processed into the spline of circumference uniform distribution; Lower non-rotating joint comprises top connection, central tube, rotary body and lower contact, top connection is threaded with rotary body, the top connection upper end is the drilling rod box, be designed with the circular hole of two symmetries on the outer wall, central tube and lower contact screwed connection, central tube can rotate relatively with top connection and rotary body, and central tube upper end inwall is designed with the spline that matches with the spline of upper non-rotating joint.
All seal by sealing ring between central tube and top connection, rotary body, the lower contact.
Seal by sealing ring between top connection and the rotary body.
The beneficial effects of the utility model are: the utility model is because adopted between central tube and top connection and the rotary body can counterrotating mode, thereby have coiled tubing and need not to rotate the function that can be connected with down-hole special tool string at well head, simple in structure, easy to operate.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of upper non-rotating joint.
Fig. 2 is the structural representation of lower non-rotating joint.
The specific embodiment:
As shown in Figure 1 and Figure 2, the non-rotating joint of a kind of continuous-tube drilling well comprises non-rotating joint 1 and lower non-rotating joint 2; Upper non-rotating joint 1 upper end is designed with the drilling rod box, and the lower end is designed to the drilling rod pin thread, and the drilling rod pin thread tip designs of upper non-rotating joint 1 becomes circular tube shaped and pipe is processed into the spline of circumference uniform distribution; Lower non-rotating joint 2 comprises top connection 3, central tube 4, rotary body 5 and lower contact 6, top connection 3 is threaded with rotary body 5, top connection 3 upper ends are the drilling rod box, be designed with the circular hole of two symmetries on the outer wall, central tube 4 and lower contact 6 screwed connections, central tube 4 can with top connection 3 and rotary body 5 relative rotations, central tube 4 upper end inwalls are designed with the spline that matches with the spline of upper non-rotating joint 1.All seal by sealing ring between central tube 4 and top connection 3, rotary body 5, the lower contact 6.Seal by sealing ring between top connection 3 and the rotary body 5.
In continuous-tube wellbore construction process, upper non-rotating joint 1 upper end box is linked to each other with continuous-tube drilling tool pin thread, the lower contact 6 of lower non-rotating joint 2 links to each other with another continuous-tube drilling tool upper end box, when needs connect drilling rod between the upper and lower non-rotating joint and buckle, collude spanner rotation top connection 3 with special use, its lower contact 6 this moment and the continuous-tube kit that is attached thereto are non-rotary, thereby have prevented the rotation of continuous-tube, drilling tool and built-in cable.
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.
