Abstract
The utility model discloses a novel arc-head petroleum drill bit, and belongs to the field of petroleum exploration tools. An arc drill bit body is fixed on a cylindrical drill body; the lower end of the cylindrical drill body is connected with a threaded section; scraper strips which are interlaced are arranged on the arc drill bit body at equal intervals; a sediment channel is formed between two scrapers; and diamond cutting teeth are formed on the scraper strips. According to the novel arc-head petroleum drill bit, the shortcomings that the conventional tricone drill bit is low in drilling speed, manufactured complicatedly and low in adaptability to a complicated stratum condition and causes accidents easily are overcome; and due to the design of the arc drill bit body, the drill bit is low in abrasion, and the service life of the drill bit is prolonged.
Description
Technical field
The utility model belongs to oil detective tools range, particularly a kind of novel circular arc head oil bit.
Background technology
At present in the exploitation of oil, natural gas and other mine drilling wells, most of usefulness be that diamond (PDC) drill bit and three gear wheels bore, it is slow that three gear wheels bore rate of penetration, makes complicatedly, poor to bad ground situation compliance, accidents happened easily; Diamond (PDC) drill bit can not adapt to the bad ground situation, the deficiency that compliance is poor.
The utility model content
The purpose of the utility model is slow to three gear wheels brill rate of penetration in the prior art, makes complicacy, and poor to bad ground situation compliance, accidents happened easily; Diamond (PDC) drill bit can not adapt to the bad ground situation; The deficiency that compliance is poor, and a kind of novel circular arc head oil bit is provided, it is characterized in that; Fixing circular arc bit body on the cylinder drill body; The connecting thread section in cylinder drill body lower end, the scraper strip that equidistant interleave distributes on the circular arc bit body is the silt passage between two scrapers.
Between two scrapers in the said circular arc bit body crown cooling water through hole is arranged.
The diamond cutting tooth is arranged above the said scraper strip.
The beneficial effect of the utility model is to overcome three gear wheels to bore rate of penetration slow, make complicated, poor to bad ground situation compliance, the deficiency that accidents happened easily, the design of circular arc bit body, bit wear is little, increases the application life of drill bit.
Description of drawings
Fig. 1 is a circular arc head oil bit structural representation.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The utility model provides a kind of novel circular arc head oil bit, explains below in conjunction with accompanying drawing.
Like Fig. 1; Shown in Figure 2; Fixing circular arc bit body 4 on cylinder drill body 5, in cylinder drill body 5 lower end connecting thread sections 6, the scraper strip 2 that equidistant interleave distributes on the circular arc bit body 4; Have above the scraper strip between 1, two scraper of diamond cutting tooth and cooling water through hole 7 is arranged between two scrapers of the silt passage 3 and the circular arc bit body crown.
Use the utility model circular arc head oil bit, because the design of circular arc bit body, scraper strip and diamond cutting tooth are not hard collisions to hard stratum; But certain cushioning effect is arranged; So the diamond cutting tooth is not easy to be injured, so bit wear is little, increase the application life of drill bit.
Claims (3)
1. a novel circular arc head oil bit is characterized in that, fixing circular arc bit body on the cylinder drill body, and the connecting thread section in cylinder drill body lower end, the scraper strip that equidistant interleave distributes on the circular arc bit body is the silt passage between two scrapers.
2. according to the said novel circular arc head oil bit of claim 1, it is characterized in that between two scrapers in the said circular arc bit body crown cooling water through hole being arranged.
3. according to the said novel circular arc head oil bit of claim 1, it is characterized in that the diamond cutting tooth is arranged above the said scraper strip.
