Abstract
The utility model discloses a non-excavation thread-gluing-preventing guiding drill rod joint which adopts the technical scheme that the joint comprises a male joint and a female joint, wherein the male joint is provided with an external thread; the female joint is provided with an internal thread; the top end of the external thread of the male joint is provided with a taper-shaped guiding ledge; the bottom end of the internal thread of the female joint is provided with a taper-shaped guiding hole matched with the guiding ledge; and the end surface of the guiding ledge and the chamfer position of the guiding hole are in double sealing surface structure. Compared with the prior art, the non-excavation thread-gluing-preventing guiding drill rod joint has the characteristics of simple structure and long service life. By adopting the non-excavation thread-gluing-preventing guiding drill rod joint, the thread invalidation phenomena that the internal thread and the external thread are subjected to thread alternating, the threads are abraded and the like as the inner thread and the external thread of two drill pipes are not concentric in the process of screwing on a non-excavation passing-through drill pipe can be avoided. The non-excavation thread-gluing-preventing guiding drill rod joint is convenient to operate and is convenient to widely apply in fields of petroleum and natural gas well drilling and the non-excavation field.
Description
Technical field
The utility model relates to non-excavation horizontal orientation and passes through the drilling rod of use, is the anti-thread gluing guide rod joint of a kind of non-excavation concretely.
Background technology
At present, in the non-excavation horizontal orientation crossing construction process, drilling rod is as the main instrument that passes through that creeps into, drilling rod is by the frequent last shackle of internal and external threads, because non-excavation horizontal orientation crossing construction is different with drilling well, drilling rod adopts handling to constant slope and by manually finishing the connection of drill rod thread, in the process that connects, influenced by human factor, in the process that two drilling rod internal and external threads that connect screw as easy as rolling off a log because screw thread fully engagement promptly do not apply bigger moment of torsion, cause the generation of cross threading thread gluing phenomenon, this type of failure phenomenon has occupied more than 80% of non-excavation drilling rod inefficacy ratio, conventional at present tool joint can't be avoided the generation of this type of phenomenon, bring bigger difficulty for non-excavation horizontal orientation crossing construction, caused bigger economic loss.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, provide a kind of simple in structure, easy to operate, effectively prevent that the anti-thread gluing guide rod joint of non-excavation of thread alternating thread gluing from appearring in screw thread.
Its technical scheme is: comprise male joint and female joint, male joint is provided with external screw thread, female joint is provided with internal thread, the externally threaded top of male joint is provided with taper guiding shoulder, the internal thread bottom of female joint is provided with the conical pilot hole that matches with the shoulder that leads, and the end face of guiding shoulder and the chamfer site of pilot hole are the double-sealing face structure.
The utility model compared with prior art, have simple in structure, long service life, effectively avoided non-excavation to pass through on the drilling rod in the button process, because two drilling rod internal and external threads decentraction that connect cause internal and external threads the advantage of thread failure phenomenons such as thread alternating, thread abrasion to occur, and simple operation is convenient in oil, gas drilling and the field extensive use of non-excavation.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
As shown in the figure, a kind of non-excavation is prevented thread gluing guide rod joint, comprise male joint 1 and female joint 2, male joint 1 is provided with external screw thread 3, female joint 2 is provided with internal thread 4, the top of the external screw thread 3 of male joint 1 is provided with taper guiding shoulder 5, and internal thread 4 bottoms of female joint 2 are provided with the conical pilot hole 6 that matches with the shoulder 5 that leads, and the end face 7 of guiding shoulder 5 and the chamfer site 8 of pilot hole 6 are the double-sealing face structure.When male joint 1 external screw thread 3 and female joint 2 internal threads 4 screwed, external screw thread 3 small ends guiding shoulder 5 at first entered in the pilot hole 6 of internal thread 4 small ends, has guaranteed the concentricity when internal and external threads 3 and 4 screws, and internal and external threads 3 and 4 meshes smoothly.Simultaneously, the end face 7 of guiding shoulder 5 and the chamfer site of pilot hole 68 adopt the double-sealing face structure, have improved the torsional strength of joint greatly.
