Abstract
The utility model relates to a special carbide-tipped drill bit dedicated to a fixed-point deep-penetration horizontal drilling device for the oil layers of an oil field. The utility model solves the problem that the prior carbide-tipped tool cannot drill sandstone and metal sleeves at the same time. The special carbide-tipped drill bit is composed of a carbide-tipped edge (1) and a drill bit body (2); wherein, the carbide-tipped edge (1) is embedded in the drill bit body (2); the side of the drill bit body (2) is provided with two symmetrical crescent flutes (3); and moreover, the other end surface of the drill bit body (2) is provided with two symmetrical fluid holes (4). The special carbide-tipped drill bit, which is mainly used for the fixed-point deep-penetration horizontal drilling of oil layers, has the advantages of simple structure, novelty, good cutting-removing property, long service life, and the like.
Description
Technical field: the utility model belongs to the extraordinary carbide drill of a kind of oil field oil layer positioning deep penetration horizontal drilling device special use.
Background technology: hard alloy cutter all is widely used in every field such as mining industry, building, road maintenances at present, but all carbide drills only are applicable to single material at present, and also not having a kind of drill bit promptly can bore metal again can rock drilling.The needed carbide drill of oil-water well oil layer positioning deep penetration horizontal drilling device can bore metal again can rock drilling, and present carbide drill does not satisfy the needs of oil layer positioning deep penetration horizontal drilling device.
Summary of the invention: the purpose of this utility model is exactly the problem at above-mentioned existence, invents a kind of extraordinary carbide drill that can bore sandstone and metal sleeve simultaneously.
The technical solution of the utility model is: this special type carbide drill is made of carbide-tipped cutter bit and drill body, wherein carbide-tipped cutter bit is embedded in the drill body, the side of drill body has the groove of selenodont symmetry, and has fluid hole in the other end of drill body symmetry.
The groove of the side selenodont symmetry of drill body is two.
The fluid hole that the other end symmetry of drill body is opened is two, and the fluid hole diameter is Φ 2mm.
The utility model compared with prior art has following advantage:
It is simple in structure, novel, chip removal is good, can bore sleeve pipe, can bore sandstone, long service life again.
Description of drawings: Fig. 1 is a structure diagram of the present utility model; Fig. 2 is an outside drawing of the present utility model.
The specific embodiment: the utility model is described further below in conjunction with accompanying drawing: it is made of carbide-tipped cutter bit 1 and drill body 2, wherein carbide-tipped cutter bit 1 is embedded in the drill body 2, the side of drill body 2 has the groove 3 of selenodont symmetry, and has fluid hole 4 in the other end of drill body 2 symmetry.
The groove 3 of the side selenodont symmetry of drill body 2 is preferably two.
Preferably two of the fluid holes 4 that the other end symmetry of drill body 2 is opened, and the fluid hole diameter is preferably Φ 2mm.
During on-the-spot the use, an end of drill body 2 is connected with the hollow flexible axle of power-type by the internal thread of M8, relies on the hollow flexible axle of power-type that power is provided, carry carbide drill rotation and feeding, at first perforate on sleeve pipe continues feeding then, continues in cement sheath, contaminated zone and rockhole.Have the fluid hole of two Φ 2mm in the other end of carbide drill body 2 symmetry, and link with the central passage of the hollow flexible axle of power-type, when boring, can penetrate High-Pressure Water, and can cool off carbide drill, the side of drill body 2 has the groove 3 of selenodont symmetry, can be used for the chip removal that circulates.
