The general core bar of existing drilling rod plug, composite drill rod plug adopts aluminium alloys or copper material to make, plug sheet be by the vulcanization of rubber on aluminium alloys or copper material framework material integral or integral installation on core bar.Original drilling rod plug, composite drill rod plug, size, lacquer disk(-sc) number are fixed, and can not need adjustment according to scene, existing completion drilling rod plug is at different size drilling rod combined string, and during use, lacquer disk(-sc) can not be changed at any time.
Utility model content
Technical problem to be solved in the utility model is, there is provided a kind of can at the construction field (site) for the composite drill rod tubing string of different size drilling rod different size internal diameter, the quick combined composite drill rod plug of on-the-spot coupling different size plug dish and plug dish number of combinations.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of quick combined composite drill rod plug, comprises bruising seal head and is connected successively at the different plug dish of multiple diameters of bruising seal head afterbody.
The front end of described bruising seal head is with twice O RunddichtringO, and rear end is provided with circular hole, and circular-hole internal-wall is with connection box, and the top of circular hole is provided with jump-ring slot; Described plug dish comprises multiple one-level plug dish and multiple secondary plug dish, one-level plug dish is arranged on one-level plug dish core body, in one-level plug dish core body front end, connecting thread pin thread is set, rear end arranges connecting thread box and jump-ring slot, one-level plug dish core body front end is with self-locking jump ring, the screw thread pin thread of one-level plug dish core body front end and self-locking jump ring are screwed in the circular hole of bruising seal head rear end, and self-locking jump ring is stuck in jump-ring slot; Secondary plug dish is arranged on secondary plug dish core body, in secondary plug dish core body front end, connecting thread pin thread is set, rear end arranges connecting thread box and jump-ring slot, and secondary plug dish core body front end is with self-locking jump ring, and secondary plug dish core body is screwed into one-level plug dish core back-end.
The beneficial effects of the utility model are:
1, the utility model solves original drilling rod plug, composite drill rod plug, and size, lacquer disk(-sc) number are fixed, can not according to the problem of the on-the-spot adjust size of field pipes string internal diameter.
2, the problem that the utility model solves original drilling rod plug, composite drill rod plug length can not put into cementing head when being fixed with.
3, the utility model can better by the composite drill rod of different size internal diameter, and seal isolation cement slurry property is good, and bruising is accurate.
