The beneficial effects of the utility model are that: scientific and reasonable's structure, it is very convenient to implement, can bore different specifications through the guide that changes in main the boring to adapt to different topography, reliable and simple has avoided changing the manpower financial resources that the drill bit consumeed, practices thrift the cost.
Description
Technical field
The utility model relates to petroleum exploration field, particularly relates to a kind of novel oil bit that can adapt to multiple environment.
Background technology
Oil, as one of indispensable non-renewable energy resources most important on the earth.Along with the exploitation that people are excessive, shallow oil is more and more rare, people transfer to ocean and deep layer gradually direction of extraction, and drill bit, as equipment indispensable in oil exploitation, has been increasing advanced person by people and has improved, more and more be applicable to Deep mining, but existing drill bit, people are long from material, and the directions such as hardness are gone to change, do not reduce the cost of production of drill bit, cost is more and more higher on the contrary.
In deep prospecting process, guide bur is absolutely necessary, and does not have the guide of guide bur, not only do not reach required destination, add drilling time, consume the application life of drill bit excessively, consume a large amount of manpower, material resources and financial resources, cause cost invisible between increase several times.
And in different terrain, before the geology of different hardness, the specification of required guide bur is not quite similar, needs to prepare to change a large amount of guide burs without specification, which increase drilling time cost, prepare different guide burs and consume a large amount of financial resources without reason.
Utility model content
Based on this, the utility model designs the new drill of the different geology of the more than enough kind of a security performance high energy, described a kind of nonpetroleum drill bit, comprise housing, described housing upper end is provided with main brill, wherein, also includes the guide bur be arranged on described main brill, described main brill top is provided with opening, and described openings of sizes equals the wide cross section, bottom of described guide bur; Described guide bur two ends are provided with clamping device;
Described clamping device comprises grip fastener, is used for connecting spring and the gunning stick of described grip fastener and described main brill inwall;
Described guide bur both sides are provided with projection;
Described grip fastener is provided with the recess hole that many groups are suitable with described projection.
Wherein, described main brill external surface is evenly provided with projection, and described projection top is provided with gauge sheet.
Wherein, described guide bur bottom is provided with telescopic arm and is connected with described main brill inner wall at end.
Wherein, tell telescopic arm and comprise mobile jib and can at the flexible auxiliary bar of described mobile jib internal freedom.
Wherein, described mobile jib top is provided with spacing ring.
Wherein, described auxiliary bar end is provided with rubber stopper.
Wherein, air is filled with in the confined space that described mobile jib and described auxiliary bar form.
The beneficial effects of the utility model are: scientific and reasonable structure, implement very convenient, specification that can be different by the guide bur in the main brill of change, thus adapt to different terrain, simple, avoid the manpower financial capacity more spent by bit change, cost-saving.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention is further described in detail.
Fig. 1 is a kind of structural representation of nonpetroleum drill bit;
Fig. 2 be a kind of nonpetroleum drill bit clamping device partial enlarged drawing.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Fig. 1 to 2, a kind of novel oil bit going for different terrain, comprise housing 1, in described housing 1 upper end, the main brill 2 that material is PDC is installed, described main brill 2 top is provided with opening, described main inside of boring is provided with the guide bur 3 that can be stretched by described opening, and described openings of sizes is equal with the wide cross section of described guide bur 3 bottom.
In order to prevent described guide bur 3 from rocking in the process of High Rotation Speed, described guide bur both sides are provided with clamping device.
Described clamping device comprises grip fastener 5, is used for connecting high strength and the spring of high life 6 of described grip fastener 5 and described main brill 2 inwall and is used for preventing described grip fastener 5 from rocking and limiting the gunning stick 7 of described grip fastener moving direction;
Described drill guide 3 both sides are provided with projection 8;
Described grip fastener 5 is provided with the recess hole 9 that many groups are suitable with described projection 8.
When the described projection 8 on described guide bur 3 enters into one group recess hole 9 time, described guide bur 3 is fixed, when the described projection 8 on described guide bur 3 enters into another group recess hole 9 time, because described guide bur 3 can elongate or shorten by relatively described main brill 2, corresponding shape, the specification just changing told guide bur 3, thus adapt to different demands.
In some optional embodiments, described main brill 2 external surface is evenly provided with wear-resisting projection 10, and described projection 10 top is provided with gauge sheet 11, increases the application life of drill bit, the size of the described main brill 2 of suitable protection.
In some optional embodiments, in order to better fix described guide bur 3, prevent its unstable and loss of causing in high speed motions, affect result of use, described guide bur 3 bottom is provided with telescopic arm 12 and is connected with described main brill 2 inner wall at end.
In some optional embodiments, tell telescopic arm and comprise mobile jib 13 and can at the flexible auxiliary bar 14 of described mobile jib 13 internal freedom.
