Abstract
The utility model discloses an improved petroleum and gas well drill bit. The improved petroleum and gas well drill bit is characterized by being composed of a drill bit body, a gauge protection part, diamond compact pieces, hard alloy pieces or glomerocryst pieces and a cutter wind, wherein the drill bit body is provided with the gauge protection part, the same plane of the gauge protection part is provided with the diamond compact pieces and the hard alloy pieces or the glomerocryst pieces in an inlay mode, and the number of the diamond compact pieces and the hard alloy pieces or the glomerocryst pieces ranges from 12 to 18. The improved petroleum and gas well drill bit is good in gauge protection effect and long in service life, a large number of well drilling costs can be saved, and the economic benefits are remarkable.
Description
Technical field
The utility model relates to a kind of improved oil and gas well drilling drill bit.
Background technology
At present, the domestic drill bit for oil and gas well drilling, the drill bit that tradition is used only has a kind of gauge sheet of carbide alloy (or glomerocryst) at gauge position, while creeping in soft formation, rate of penetration is fast, drilling depth is many, but when compared with hard formation, gauge position meeting Fast Wearing, to losing gauge ability, cause hole shrinkage, drill bit is scrapped.The main cause that causes this kind of phenomenon is that the carbide alloy (or glomerocryst) at gauge position has certain hardness, but when formation rock hardness is during higher than carbide alloy (or glomerocryst) hardness, carbide alloy (or glomerocryst) meeting Fast Wearing, thereby make bit gauge protection position Fast Wearing, lose gauge ability.
Summary of the invention
The utility model has overcome the defect of above-mentioned existence, and object is in compared with hard formation, to guarantee not undergauge of drilling well for solving, and a kind of improved oil and gas well drilling drill bit is provided.
The improved oil and gas well drilling drill bit of the utility model content Description:
The improved oil and gas well drilling drill bit of the utility model, it is characterized in that: by bit body, gauge part, diamond compact, hard metal tip or synneusis sheet and wing, formed, on bit body, be provided with gauge part, mosaic diamond composite sheet, hard metal tip or synneusis sheet on same plane on gauge part, diamond compact, hard metal tip or synneusis sheet are 12～18.
Gauge of the present utility model is effective, and long service life can be saved a large amount of drilling costs, remarkable in economical benefits.
Accompanying drawing explanation
Fig. 1 is improved oil and gas well drilling drill bit structure schematic diagram;
In figure: the 1st, bit body, the 2nd, gauge part, the 3rd, diamond compact, the 4th, hard metal tip or synneusis sheet, the 5th, wing.
The specific embodiment
The improved oil and gas well drilling drill bit of the utility model is achieved in that below in conjunction with accompanying drawing and illustrates.See Fig. 1, improved oil and gas well drilling drill bit, by: bit body 1, gauge part 2, diamond compact 3, hard metal tip or synneusis sheet 4 and wing 5 form, on bit body 1, be provided with gauge part 2, mosaic diamond composite sheet 3, hard metal tip or synneusis sheet 4 on same plane on gauge part 2, diamond compact 3, hard metal tip or synneusis sheet 4 are 12～18.
The utility model is in normal drilling process, and diamond compact plays auxiliary gauge effect, thereby the utility model drill bit has with the equally good service behaviour of common diamond bit.Diamond compact, has strengthened the gauge ability of carbide alloy or glomerocryst, when boring while meeting compared with hard formation, can reach and effectively prevent hard metal tip or the heavy wear of glomerocryst experience, effectively guarantees not undergauge of drilling well, has reduced the generation of bit freezing phenomenon.
