Abstract
The utility model discloses a drill bit for cyclone well drilling, which comprises a drill bit body and a modulating board. The drill bit body is provided with a hollow cavity of the drill bit, the end of the drill bit body is provided with a drill bit runner deviating from the axis of the drill bit body, the modulating board is hermetically arranged in the cavity of the drill bit, and a tangential through hole deviating from the axis of the drill bit body is formed on the modulating board, and is communicated with the drill bit runner. The rotary jet flow is generated in the well drilling operation and can be used for cleaning and cooling the drill bit, a large amount of rock debris can be prevented from being adhered on the drill bit, and the temperature rise of the drill bit caused by well drilling operations can be effectively reduced; moreover, the rotary flow field can be formed at the well bottom, the stress condition of rocks at the well bottom can be improved, so that the rock breaking efficiency can be improved, the life of the drill bit is prolonged, the well drilling speed is improved, and the well drilling cost is lowered.
Description
Technical field
The utility model relates to the bit technique field that oil, gas drilling are used, and specifically, relates to a kind of eddy flow drilling bit.
Background technology
Along with each main force oil field, land enters development phase middle and later periods, deep-well, ultradeep well drilling technology are studied very urgent.If a large amount of landwaste that produce in the drilling process of deep drilling can not in time be removed, can cause bit balling, Repeated Cutting, cause mechanical performance to reduce, and the acceleration cutting teeth is in the wearing and tearing in shaft bottom, have a strong impact on the life-span of drill bit, the development to deep-well, ultradeep well drilling technology is significant with the optimization drill bit design therefore to improve bottom-hole flow field.
The utility model content
Technical problem to be solved in the utility model is: a kind of eddy flow drilling bit that can in time clean and cool off drill bit, raising bit speed, prolong bit life, reduction drilling cost is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: the eddy flow drilling bit, comprise drill body, and described drill body has the drill bit cavity of hollow, and the end of described drill body is provided with departs from the drill bit runner that the drill body axis is provided with; Modulation panel, the periphery of described modulation panel is connected with the inner wall sealing of described drill bit cavity, and described modulation panel is provided with the tangential through hole that departs from described drill body axis; Described tangential through hole is communicated with described drill bit runner.
As optimized technical scheme, the center line of the center line of described tangential through hole and described drill bit runner intersects.
As optimized technical scheme, the central lines of the center line of described tangential through hole and described drill bit runner.
Owing to adopted technique scheme, the beneficial effects of the utility model are: eddy flow drilling bit of the present utility model is when drilling well, drilling fluid is through the drill bit cavity, by the tangential drill bit runner that is communicated with it that injects of the tangential through hole on the modulation panel, in drill bit high speed rotary drilling process, drilling fluid is rotation at a high speed in the drill bit runner, modulation, produce rotating jet and arrive bit nozzle,, drill bit is cleaned and cools off by nozzle ejection rotating jet, prevent that a large amount of landwaste that produce in the drilling process from adhering to drill bit, and effectively reduction heats up because of the drill bit that drillng operation caused, and the rotational flow field that forms in the shaft bottom, can also improve the force-bearing situation of bottom rock, thereby can improve the efficiency of breaking rock of drill bit, prolong bit life, improve bit speed, reduce drilling cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structure sectional view of the utility model embodiment;
Among the figure: the 1-drill body; The tangential through hole of 2-; 3-drill bit runner; 4-drill bit cavity; The 5-modulation panel; The 6-bit nozzle.
The specific embodiment
As shown in drawings, the eddy flow drilling bit comprises drill body 1, and described drill body 1 has the drill bit cavity 4 of hollow, and the end of described drill body 1 is provided with departs from the drill bit runner 3 that the drill body axis is provided with; Modulation panel 5, described modulation panel 5 sealings are arranged in the described drill bit cavity 4, and described modulation panel 5 is provided with the tangential through hole 2 that departs from described drill body 1 axis; Described tangential through hole 2 is communicated with described drill bit runner 3, and the end of described drill body 1 also is provided with bit nozzle 6.
In the present embodiment, the center line of the center line of described tangential through hole 2 and described drill bit runner 3 intersects.
As another kind of situation, the center line of described tangential through hole 2 also can overlap with the center line of described drill bit runner 3.
Operating principle: eddy flow drilling bit of the present utility model is when drilling well, drilling fluid is through drill bit cavity 4, by the 2 tangential drill bit runners 3 that are communicated with it that inject of the tangential through hole on the modulation panel 5, in drill bit high speed rotary drilling process, drilling fluid is rotation at a high speed in drill bit runner 3, modulation, produce rotating jet and arrive bit nozzle 6, by bit nozzle 6 ejection rotating jets, drill body 1 is cleaned and cools off, prevent that a large amount of landwaste that produce in the drilling process from adhering to drill bodies 1, and the drill bit that effectively reduces because of drillng operation caused heats up, and the rotational flow field that forms in the shaft bottom, can also improve the force-bearing situation of bottom rock, thereby can improve the efficiency of breaking rock of drill bit, prolong bit life, improve bit speed, reduce drilling cost.
The above only is giving an example of the utility model specific embodiment, does not address part in detail and is those skilled in the art's common practise.Protection domain of the present utility model is as the criterion with the content of claim, and any equivalent transformation that carries out based on technology enlightenment of the present utility model is also within protection domain of the present utility model.
