Description
Technical field
The utility model relates to winning equipment field, is specially drag bit.
Background technology
A kind of cut drill with fin that oil drilling is conventional in the broken ground of top.Have double-vane, three wings, four wings point the drag bit of tens wings (also occurred nearly), the most frequently used is three wings drag bits.Stairstepping is had and without step-like two kinds (being divided into interior ladder, outer ladder, flat three classes), its blade welding-on has carbide alloy or diamond bottom fin.As required, drag bit is divided into again two classes of coring He not coring.Be suitable for stratum: dead-soft, soft, in hard.
Drag bit is a kind of drill bit used in rotary drilling the earliest, and structure is simple, easily manufactured, with low cost, reaches the soft formation such as mud stone and shale of 4 grades for creeping into drillability.Drag bit due to drill bit bearing area large, when creeping into hard formation or the staggered hard interbedded layer of soft or hard, drill bit incision difficulty, drilling efficiency is low.Along with inserted drag bit, the succeeding in developing of diamond drag bit, improve and expand drilling efficiency and the scope of application of drag bit.
The drill bit in parabola cutting face is had significantly to raise the efficiency than traditional resistance drill bit, improve the strength that stock-removing efficiency causes minimizing cutting force and thrust to apply, this is an important lifting, reduce horsepower and just mean the material needing to cut down some, reduce horsepower and mean reduction capital and operation cost.On the other hand, if input power remains unchanged, to cut compared with provided resistance drill bit or mining rate significantly improves.
Although the kind of drill bit is a lot, but the actual conditions in mining process are also diversified, existing drill bit can not meet diversified demand in mining activity, and the equipment replacement drill bit that stops during bit damage in addition also reduces the efficiency of mining to a certain extent.
