Abstract
The utility model discloses an oil hollow drill rod which comprises a cylindrical main rod body (3). A drill shaft body (4) is arranged in the middle of the main rod body (3). A plurality of axially-distributed arc-shaped grooves (6) are distributed on the circumferential face of the drill shaft body (4). A drill edge column (5) is formed between any two arc-shaped grooves (6). A through hole (1) penetrating through the main rod body (3) and the drill shaft body (4) is formed inside the main rod body (3). The oil hollow drill rod can well and timely discharge inside slurry generated in the process of well drilling, can not stuck, ensures normal operation, and is high in reliability and long in service life.
Description
Technical field
The utility model relates to a kind of oil drilling tools, specifically is the oil hollow drill for oil drilling, belongs to the petroleum machinery field.
Background technology
Hollow drill is when degree of depth drilling well, can produce drilling well excretas such as many native bits, aggregate chips and mud in the drilling well, when causing the obstruction in the well if these excretas can not in time, well be discharged, not only drill bit, drilling rod etc. is damaged, but also problems such as drill bit is stuck, drilling rod can not move can appear, not only rig has been caused and destroyed but also influenced the operating efficiency of rig, be unfavorable for practicality and development.
The utility model content
The utility model provides a kind of oil hollow drill, has solved the drilling well when drilling well of oil hollow drill in the past and has stopped up the drilling rod destruction that causes, stuck problem.
The technical scheme that the utility model provides is: the oil hollow drill, comprise columniform main rod body, described main rod body interlude is provided with the auger spindle body, auger spindle body periphery is provided with the arc groove of several axial distribution, form the drill lip post between described any two arc grooves, also be provided with the through hole that runs through main rod body and auger spindle body in the described main rod body.The drill lip post can carry out the secondary drilling well to the borehole wall, improves smoothness and the planeness of the borehole wall, reinforces the borehole wall.
Further, wantonly one or two end face of described main rod body is provided with locating shaft, and described through hole runs through locating shaft.Oil drill rocker locating shaft when connecting prevents that with oil drill rocker and connector location oil drill rocker from occurring tilting, and guarantees the guidance quality of oil drill rocker and connector.
Further, the length of described locating shaft is 5-8 centimetre.Locating shaft mainly is to play well location and a guide function when connecting; Consider the problem of locating shaft location and guiding intensity and material, the length of locating shaft is decided to be 5-8 centimetre, when using minimal material, strengthen its location and guiding intensity.
Further, described arc groove is provided with 8 altogether, is circularly and evenly distributed each other.Arc groove be provided with altogether 8 then the drill lip post also have 8, can reach very high operating efficiency during the work of 8 drill lip posts.
Further, described main rod body and auger spindle body material adopt the WC carbide alloy.A kind of alloy material that the WC carbide alloy is made by powder metallurgical technique by hard compounds and the binding metal of refractory metal.The WC carbide alloy has a series of premium properties, particularly its high rigidity and abrasion resistance such as hardness height, wear-resisting, intensity and toughness is better, heat-resisting, corrosion-resistant, even also remain unchanged substantially under 500 ℃ temperature, still has very high hardness in the time of 1000 ℃.So main rod body and auger spindle body adopt the WC Hardmetal materials can not only satisfy the job requirement of down-hole, and its abrasion resistance is extremely strong, has prolonged the application life of oil drill rocker greatly.
Further, described main rod body and auger spindle surface scribble one deck antirust oil enamelled coating.Cause environment in well is abominable, soil has very strong corrosivity, easily main rod body and auger spindle body are damaged, so be coated with the antirust oil enamelled coating for preventing main rod body and auger spindle body and the extraneous chemical reaction that produces in main rod body and auger spindle surface, thereby improve the application life of main rod body and auger spindle body, strengthened reliability and the safety of oil drill rocker.
Advantage of the present utility model is: this oil hollow drill of the utility model design, the inside mud that drilling well produces can be fine, discharge timely, the stuck problem of oil drill rocker can not occur, guarantees the normal operation of oil drill rocker, and the reliability height, long service life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Label among the figure is expressed as respectively: 1, through hole; 2, locating shaft; 3, main rod body; 4, auger spindle body; 5, drill lip post; 6, arc groove.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but embodiment of the present utility model is not limited thereto.
Embodiment
Referring to Fig. 1, the oil hollow drill, comprise columniform main rod body 3, described main rod body 3 interludes are provided with auger spindle body 4, auger spindle body 4 peripheries are provided with the arc groove 6 of several axial distribution, form drill lip post 5 between described any two arc grooves 6, also be provided with the through hole 1 that runs through main rod body 3 and auger spindle body 4 in the described main rod body 3.
Described main rod body 3 wantonly one or two end face are provided with locating shaft 2, and described through hole 1 runs through locating shaft 2.
The length of described locating shaft 2 is 5-8 centimetre.
Described arc groove 6 is provided with 8 altogether, is circularly and evenly distributed each other.
Described main rod body 3 and auger spindle body 4 materials adopt the WC carbide alloy.
Described main rod body 3 and auger spindle body 4 surfaces scribble one deck antirust oil enamelled coating.
The utility model can not only well be located when connecting, guarantee guidance quality, the mud that produces in drilling process simultaneously can well be discharged by arc groove 6, stuck, the irremovable problem of drilling rod of avoiding stopping up in the well and causing, guarantee oil drill rocker, also reduced accident rate, the reliability height is beneficial to use.
Can well realize the utility model as mentioned above.
