Abstract
The utility model discloses a PDC drill bit for oil drilling and belongs to the technical field of oil exploitation equipment. According to the technical scheme, the PDC drill bit comprises a drill bit body and is characterized in that the drill bit body is provided with main blades, auxiliary blades and nozzles, the main blades and the auxiliary blades are all provided with PDC cutting teeth, the six nozzles are distributed evenly, a guide drill is arranged in the center of the top of the drill bit body, and the guide drill is a cross-shaped drill bit. Compared with the prior art, the PDC drill bit for oil drilling has the advantages of being reasonable in structural design and safe and reliable to use. Stability and anti-shock capacity of the drill bit are improved effectively, the service life of the drill bit is prolonged, borehole tilt can be prevented, the well drilling efficiency is improved, and meanwhile cost is saved.
Description
Technical field
The utility model relates to the oil exploration equipment technical field, and outstanding tool relates to a kind of oil drilling PDC drill bit.
Background technology
At present, the PDC drill bit is the special-purpose brill drilling bit that substitutes old-fashioned rock bit of oil gas field, and it has the characteristics such as high-wearing feature, anti-oblique, anti-mud drum, high rotating speed, and is described as " three height " product of high-tech, high investment, high production.In drilling process, the PDC drill bit has the performance advantages such as high drilling speed, low the pressure of the drill, high drilling depth, and it can reduce the cost of winning in oil field greatly in the application of drilling process, accelerates exploitation rate, improves the economic benefit in oil field.The PDC drill bit of prior art, in creeping into straight well or directional well vertical section process, easily causes the well got out to tilt, and in order to prevent well, tilts, and usually needs to reduce the pressure of the drill of PDC drill bit, has affected exploitation rate.
The utility model content
The purpose of this utility model is the deficiency existed for prior art, a kind of oil drilling PDC drill bit is provided, it has advantages of reasonable in design, safe and reliable, stability and the impact resistance of drill bit have effectively been improved, increased the application life of drill bit, and can prevent that well from tilting, cost-saving when improving drilling efficiency.
The purpose of this utility model is achieved through the following technical solutions: a kind of oil drilling PDC drill bit, comprise bit body, be provided with the operator wing, secondary wing and nozzle on described bit body, be provided with the PDC cutting teeth on the described operator wing and secondary wing, described nozzle be six uniform, the center of top of described bit body is provided with a guide bur, and described guide bur is cross bit.
As further improvement of the utility model, the described operator wing be three uniform, the planform of the operator wing is spiral of Archimedes, and operator is equipped with six PDC cutting teeths on the wing.
As of the present utility model, further improve, described secondary wing be three uniform, the planform of secondary wing is spiral of Archimedes, and three PDC cutting teeths are installed on secondary wing.
As another step of the present utility model, improve, described bit body, the operator wing, secondary wing and drill guide are one-body molded.
The beneficial effects of the utility model are: the utlity model has reasonable in design, safe and reliable advantage, stability and the impact resistance of drill bit have effectively been improved, increased the application life of drill bit, and can prevent that well from tilting, cost-saving when improving drilling efficiency.
The accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Wherein, 1-bit body; The 2-wing of operating; The secondary wing of 3-; 4 nozzles; The 5-PDC cutting teeth; The 6-guide bur.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by a specific embodiment, and, in conjunction with its accompanying drawing, this programme is set forth.
By accompanying drawing 1, can find out, the oil drilling of this programme PDC drill bit, comprise bit body 1, be provided with the operator wing 2, secondary wing 3 and nozzle 4 on described bit body 1, be provided with PDC cutting teeth 5 on the described operator wing 2 and secondary wing 3, described nozzle 4 be six uniform, the center of top of described bit body 1 is provided with a guide bur 6, described guide bur 6 is cross bit.In addition, the described operator wing 2 be three uniform, the planform of the operator wing 2 is spiral of Archimedes, and operator is equipped with six PDC cutting teeths 5 on the wing 2; Described secondary wing 3 be three uniform, the planform of secondary wing 3 is spiral of Archimedes, and three PDC cutting teeths 5 are installed on secondary wing 3; Described bit body 1, the operator wing 2, secondary wing 3 and drill guide 6 are one-body molded.
The utlity model has reasonable in design, safe and reliable advantage, effectively improved stability and the impact resistance of drill bit, increased the application life of drill bit, and can prevent that well from tilting, cost-saving when improving drilling efficiency.
Above disclosed be only a preferred embodiment of the present utility model; but be not limited to the utility model; all within spirit of the present utility model and principle; the modification of doing, polish, be equal to replacement etc.; within all should being included in protection domain of the present utility model; in addition, the utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
