Abstract
The utility model relates to a PDC (polycrystalline diamond compact) drill bit with gauge teeth. The PDC drill bit comprises a drill bit body and at least two blades arranged on the periphery of the drill bit body at intervals, at least one cutting tooth is arranged on each blade, a water jet hole is formed in the drill bit body, and gauge mats are arranged on the blades, positioned below the cutting teeth and respectively provided with two rows of gauge teeth and a chip collecting groove. The PDC drill bit is simple in structure, high in drilling speed, small in torque, high in drilling efficiency, stable in operation and long in service life.
Description
Technical field
The utility model belongs to the technical field of geological drilling with drill bit, particularly a kind of PDC drill bit with gauge teeth.
Background technology
At present in geological prospecting, exploitation, use in a large number the PDC drill bit in oil drilling, PDC drill bit in the past mainly take there is carcass the PDC drill bit as main, manufacture matrix drill bits and need to use tungsten, manganese, the metals such as nickel, yet the scarcity of these metal material and non-renewable, impel people finding the substitute of carcass always, so having the PDC drill bit of steel body has occurred, this steel body formula PDC drill bit cost is lower than matrix drill bits, and performance and matrix drill bits no significant difference, its drilling safety performance is greater than matrix drill bits, due to above advantage, steel body formula PDC drill bit is subject to user's favor very soon, obtain a large amount of popularizations and application in drilling well.But current steel body formula PDC drill body is not wear-resisting, the application life of having reduced drill bit, and in use moment of torsion is larger, has reduced the drilling efficiency of drill bit.

Wherein, the material of described rear row's gauge teeth (7) is PDC tooth, TSP tooth or impregnated tooth.
Wherein, described cutting teeth (3) is upper by being welded to connect at described wing (2), and described front-seat gauge teeth (4) and described rear row's gauge teeth (7) are welded to connect on described gauge pad (8).
Wherein, the surface of described drill body (1) has wearing layer.
By said structure, the following technique effect of realization of the present utility model:
(1) the PDC drill bit is the double gauge form with the crumb loading groove, simple in structure, drilling speed is fast, moment of torsion is little, and drilling efficiency is high.
(2) gauge that after, row's gauge teeth can effectively be protected drill bit is undergauge not, the drill bit stable working.
(3) by increasing wearing layer and the gauge structure of drill body, extend the application life of drill bit.
