Abstract
The invention discloses a PDC (polycrystalline diamond compact) bit for oil drilling, and belongs to the technical field of oil production devices. The technical scheme includes that the PDC bit comprises a drilling rod and a bit body and is characterized in that the drilling rod and the bit body are screwed, a primary bit wing, a secondary bit wing and six nozzles are arranged on the bit body, PDC cutting teeth are arranged on the primary bit wing and the secondary bit wing, the six nozzles are uniformly distributed, a guide drill is arranged at the center of the top of the bit body, and the guide drill is a cross bit. Compared with the prior art, the PDC bit has the advantages of reasonable structural design and safety and reliability in use, stability and impact resistance of the bit are effectively improved, the service life of the bit is prolonged, inclination of a drill hole can be prevented, and cost is saved while drilling efficiency is improved.
Description
Technical field
The present invention relates to oil exploration equipment technical field, relate in particular to a kind of oil drilling PDC drill bit.
Background technology
At present, PDC drill bit is the special-purpose drilling bit that substitutes old-fashioned rotary drill of oil gas field, and it has the features such as high-wearing feature, high impact-resistant, 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, 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 is generally integral structure, after the head wearing and tearing of drill bit, need to, by whole bit change-over, so not only waste material, and use cost improve greatly.Simultaneously, this PDC drill bit is in drilling process, easily cause the well getting out to tilt, in order to prevent that well from tilting, conventionally need to reduce the rotating speed of PDC drill bit, or with straight hole of a thinner drill bit subdrilling, and then with the reaming of PDC drill bit, so just cause the efficiency of boring lower, affect exploitation rate.
Summary of the invention
The object of the invention is the deficiency existing 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 object of the invention is to be achieved through the following technical solutions: a kind of oil drilling PDC drill bit, comprise drilling rod and bit body, described drilling rod and bit body are screwed, on described bit body, be provided with the operator wing, secondary wing and nozzle, on the described operator wing and secondary wing, be provided with PDC cutting teeth, described nozzle be six uniform, the center of top of described bit body is provided with a guide bur, described guide bur is cross bit.
Foregoing PDC drill bit, preferred scheme is: the described operator wing be three uniform, the planform of the operator wing is spiral of Archimedes, and on the operator wing, six PDC cutting teeths is installed.
Foregoing PDC drill bit, preferred scheme is: 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.
Foregoing PDC drill bit, preferred scheme is: described bit body, the operator wing, secondary wing and drill guide are one-body molded.
The invention has the beneficial effects as follows: the present invention has advantages of reasonable in design, safe and reliable, by bit body is screwed together on drilling rod, thereby facilitated the replacing of bit body, reduced use cost; By setting up a guide bur, the drilling direction that it can guide this PDC drill bit, prevents that well from tilting, cost-saving when improving drilling efficiency.
