Abstract
The utility model discloses a drill rod capable of preventing a drill bit from being buried. The drill rod comprises a rod body, wherein an inner cavity is formed in the middle of the rod body; outer threads are formed at the front end of the rod body; inner threads are formed at the back end of the rod body; the outer threads correspond to the inner threads; exhaust holes are formed in the wall of the rod body; a plurality of sand-scraping plates are fixedly connected outside the wall of the rod body; the sand-scraping plates are arranged along the length direction of the rod body, and are distributed radially and uniformly by taking the axis of the rod body as the center; the inner threads at the back end of the rod body are fixedly connected with a baffle ring. The drill rod is applied to rescue and relief when the drill bit is buried due to collapse during well drilling. In the rotating process of the drill rod, the sand-scraping plates outside the rod body can be used for loosening sediment, and air current flows out of the inner cavity through the exhaust holes to drive the sediment in order to get through a well wall.
Description
Technical field
The utility model relates to the drilling rod that a kind of drilling well is used, and relates in particular to a kind of anti-drilling rod of burying drill bit.
Background technology
In drilling well drilling process, often easily run into borehole wall top section landslide, if run into landslide, buriedly often cannot take out at the drill bit of down-hole and the drilling rod of bottom, cause the waste of resource and economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-drilling rod of burying drill bit, if run into soil landslide in drilling process, bury drill bit and cannot take out, the utility model can easily be got through the landslide borehole wall, the convenient drilling rod that takes out drill bit and buried portion in the time of rescue.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of anti-drilling rod of burying drill bit, comprise the body of rod, the body of rod is middle with inner chamber, lever front end is with external screw thread, and body of rod rear end is with internal thread, and external screw thread is corresponding with internal thread, it is characterized in that: on the wall of the body of rod, have steam vent, body of rod wall outside is fixedly connected with multiple sand scrapers, and sand scraper is along the length direction setting of the body of rod, and sand scraper is radial and is uniformly distributed centered by the axis of the body of rod.
According to described anti-drilling rod of burying drill bit, it is characterized in that: the described internal thread place of described body of rod rear end is fixedly connected with baffle ring.
The utility model is a kind of relief drilling rod of speedily carrying out rescue work of burying drill bit for run into landslide in drilling well, in the time running into borehole wall collapse, use this drilling rod, in rotation process, the sand scraper of body of rod outside can become flexible silt, air-flow flows out through inner chamber from steam vent, gets through the borehole wall thereby promote silt.
