Abstract
The utility model relates to a high-energy percussion rock-breaking PDC (polycrystalline diamond compact) drill bit and overcomes the defect that since nozzles of the existing PDC drill bit are lower than a bit body, the existing PDC drill bit is not theoretically satisfactory to rock breaking for complex formations and overall drilling acceleration is restrained. The high-energy percussion rock-breaking PDC drill bit comprises a crown, blades, and nozzles. The nozzle is fixedly disposed at the front end of the crown and is lower than the surface of the crown. The non-evenly distributed blades are disposed at the front end of the crown. Cutting teeth are fixedly mounted on the blades. The jet nozzles (4) are fixedly mounted at the front end of the crown (3) and between adjacent blades (1). Axes of the jet nozzles (4) are parallel to the sides of the blades (1). The front end of each jet nozzle (4) protrudes the surface of the crown (3). The high-energy percussion rock-breaking PDC drill bit has the advantages that the structure is reasonable, mechanical drilling speed of the drill bit can be greatly increased during drilling, the service life of the drill bit is prolonged, drilling period is shortened, and drilling cost is reduced.
Description
Technical field
The utility model relates to a kind of probing PDC drill bit, especially relates to the broken rock PDC drill bit of a kind of high energy impact.
Background technology
The PDC drill bit mainly is made up of bit body (carcass), cutting teeth, nozzle, guarantor's footpath material and connector etc., relies on cutting teeth cutting stratum to implement to creep into.Nozzle is drill bit inner chamber and outside waterpower passage, and it is the bottom-hole cleaning that nozzle mainly acts on, and the landwaste band from the shaft bottom, is prevented bit balling, reduces Repeated Cutting, improves efficiency of breaking rock, also has the hydraulic drilling effect in addition under certain drilling parameter.The size of hydrophthalmia and number needs are definite according to bottom-hole flow field, otherwise can influence efficiency of breaking rock, cause premature bit failure, influence the duration.Existing PDC bit nozzle is fixedly mounted on the leading section of bit body, and is lower than the bit body surface, does not reach theoretical requirement for the bad ground rock breaking efficiency, has restricted the whole speed-raising of drilling well.
The utility model content
Be lower than the bit body surface in order to overcome existing PDC bit nozzle, do not reach theoretical requirement for the bad ground rock breaking efficiency, the deficiency of the whole speed-raising of restriction drilling well, the utility model provides a kind of high energy impact to break rock PDC drill bit.
The technical scheme that its technical problem that solves the utility model adopts is: the broken rock PDC drill bit of high energy impact comprises drill bit hat, wing, nozzle, nozzle is fixedly mounted on the leading section of drill bit hat and is lower than the surface of drill bit hat, drill bit hat leading section is provided with the wing of non-uniform Distribution, be installed with cutting teeth on the wing, between the leading section of drill bit hat, adjacent wing, be installed with injection nozzle; The axis of injection nozzle and the parallel sided of wing; The front end of injection nozzle protrudes in drill bit hat surface, and the height that injection nozzle protrudes in drill bit hat surface is 1～100mm.
The beneficial effects of the utility model are, and are rational in infrastructure, can increase substantially the rate of penetration of drill bit when creeping into, and prolong the application life of drill bit, shorten drilling period, reduce drilling cost.
Description of drawings
Fig. 1 is the broken rock PDC drill bit schematic diagram of the utility model high energy impact.
Among the figure: 1. wing, 2. nozzle, 3. drill bit hat, 4. injection nozzle.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.But what those skilled in the art should know is to the invention is not restricted to the listed specific embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.
Referring to accompanying drawing 1.The utility model high energy impact breaks rock PDC drill bit, comprise drill bit hat 3, wing 1, nozzle 2, nozzle 2 is fixedly mounted on the leading section of drill bit hat 3 and is lower than the surface of drill bit hat 3, and drill bit is preced with the wing 1 that 3 leading sections are provided with non-uniform Distribution, is installed with cutting teeth on the wing 1.Be installed with injection nozzle 4 between the leading section of drill bit hat 3, adjacent wing 1, the installation of injection nozzle 4 can be adopted interchangeable or fixing different mounting means.The parallel sided of the axis of injection nozzle 4 and wing 1 prevents that direct drill hammer wing of mud liquid and composite sheet from damage it.The front end of injection nozzle 4 protrudes in drill bit and is preced with 3 surfaces, and projecting height is 1～100mm; Injection nozzle 4 quantity are 1～20, adopt the injection nozzle 4 of interchangeable installation to be threaded with 3 employings of drill bit hat.
The utility model of the broken rock PDC drill bit of the utility model high energy impact is according to actual conditions such as formation drillability and equipment, the efficient rock-breaking injection nozzle of being furnished with varying number and different proud exposures, can increase substantially the rate of penetration of drill bit, increase the application life of drill bit, shorten drilling period, reduce drilling cost.
It should be noted that the foregoing description is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiments and not break away from the claim scope of this patent.
Claims (2)
1. a high energy impact breaks rock PDC drill bit, comprise drill bit hat, wing, nozzle, nozzle is fixedly mounted on the leading section of drill bit hat and is lower than the surface of drill bit hat, and drill bit hat leading section is provided with the wing of non-uniform Distribution, be installed with cutting teeth on the wing, it is characterized in that:
Between the leading section of described drill bit hat (3), adjacent wing (1), be installed with injection nozzle (4); The parallel sided of the axis of injection nozzle (4) and wing (1); The front end of injection nozzle (4) protrudes in drill bit hat (3) surface.
2. according to the broken rock PDC drill bit of the described high energy impact of claim 1, it is characterized in that: the height that described injection nozzle (4) protrudes in drill bit hat (3) surface is 1～100mm.
