Abstract
A drill for oil exploration comprises a joint connected with a drilling machine, the joint is provided with an annular groove, the bottom end of the joint is connected with a drill bit, a passage is formed inside the drill bit, the bottom end of the drill bit is provided with an explosive outlet, the outer surface of the drill bit is provided with an alloy tooth, the bottom end of the drill bit is provided with drill wings by taking the axial center line of the drill bit as a center, and the center of the bottom end of the drill bit is provided with a positioning head. The drill disclosed by the utility model can be widely applied to the exploration operation in oil fields; the drill is simple in structure and convenient to use; an explosive can be directly put into the passage so as to complete the explosive placement work; the three drill wings are arranged so as to enhance the stability of the drill when the drill works, so the service life of the drill is prolonged; and in addition, the joint and the positioning head are arranged so as to ensure the precise positioning of the drill and effectively improve the working efficiency.
Description
Technical field:
The utility model relates to geological prospecting apparatus field, especially relates to a kind of oil exploration drill bit.
Background technology:
The oil exploration rig is the critical machine of oil exploration and the probing of geology mining site, and drill bit wherein is broken formation, forms the instrument of well head, and its parameters quality is directly connected to the height of rig efficient and the overall performance of rig.Be used for the oil mine prospection general use be the scraper type drill bit, it mainly relies on the shearing broken rock, exist bit wear fast, problems such as drilling efficiency shortcoming, and the position error of drill bit is bigger, and discontinuity easily influences operating efficiency, also have existing drill bit seldom can satisfy the requirement of transferring exploration explosive from the centre, oneself can not satisfy the needs of current oil and relevant geological prospecting.
The utility model content:
The purpose of this utility model provides a kind of oil exploration drill bit, and this utility model has simple in structure, and is easy to use, the advantage of the stability when having increased drill bit work.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of oil exploration drill bit, comprise the joint that is connected with rig, it is characterized in that: joint is provided with annular groove, the joint bottom connects drill bit, drill bit internal is provided with passage, and the bottom is provided with medicine outlet, and the drill bit external surface is provided with carbide button, the drill bit bottom is provided with the brill wing centered by the drill bit longitudinal center line, and the center of drill bit bottom is provided with positioning head.
The described brill wing equidistantly distributes in the drill bit bottom.
The described brill wing is three.
Described medicine outlet is between positioning head and the brill wing.
Effect intentionally of the present utility model is: the utility model can be widely used in the oil field prospecting operation, simple in structure, easy to use, can directly medicine be put into passage, can finish the work of blowing out, the stability when three brill wings have increased drill bit work, improved drilling life of bit, in addition, guaranteed that by the setting of joint and positioning head the location of drill bit is accurate, can effectively increase work efficiency.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
With reference to Fig. 1, a kind of oil exploration drill bit, comprise the joint 1 that is connected with rig, joint 1 is provided with annular groove, and joint 1 bottom connects drill bit 4, and drill bit 4 inside are provided with passage 2, the bottom is provided with medicine outlet 5, drill bit 4 external surfaces are provided with carbide button 3, and drill bit 4 bottoms are provided with the brill wing 6 centered by drill bit 4 longitudinal center lines, and the center of drill bit 4 bottoms is provided with positioning head 7.The described brill wing 6 equidistantly distributes in drill bit 4 bottoms.The described brill wing 6 is three.Described medicine outlet 5 is between positioning head 7 and the brill wing 6.During use joint 1 is connected on the rig, again by passage 2 will blow out medicine send into the bottom get final product.The utility model can be widely used in the oil field prospecting operation, simple in structure, easy to use, can directly medicine be put into passage 2, can finish the work of blowing out, the stability when three brill wings 6 have increased drill bit 4 work, 4 application lifes of drill bit have been improved, in addition, guaranteed that by the setting of joint 1 and positioning head 7 location of drill bit 4 is accurate, can effectively increase work efficiency.
