Abstract
The utility model relates to a disc valve revolving drilling tool, which comprises a rotor, a disc valves, a joint, a hammer, a cylinder, a drill and a connecting rod, wherein the upper cover and the side wall of the disc valve outer jacket are respectively provided with a through hole, the upper end of the joint is uniformly provided with three through holes along the peripheral direction, the side wall is provided with two through holes, the hammer is inserted in inner cavity of the joint to be sealed with the inner cavity in a sliding way, the joint is in screwed connection with the cylinder, the other end of the cylinder is in splined connection with the drill, and the drill has up-and-down movement stroke, and is provided with two inclined through holes. In the utility model, the rotor is used to drive the disc valve to open or close to generate pressure difference so as to realize the vibration drilling. Because the spring and the rubber piece are arranged in the tool, the liquid flow can not suddenly break, the corrosion resistance is strong, and the service life is long. In addition, the tool is integrally in a full iron design, the sufficiency impact force can be obtained by adjusting the mass of the hammer, and the rock breaking efficiency can be improved.
Description
Technical field:
The utility model relates to a kind of oil drilling class instrument, a kind of specifically vibratory drilling instrument.
Background technology:
Vibratory drilling is significant to deep drilling, especially can be good at improving efficiency of breaking rock in the deep-well hard formation, thereby improves rate of penetration.In air drilling, very high rate of penetration has been created in the use of air hammer, uses in a large number.But under the drilling fluid drilling condition, the present vibratory drilling instrument that occurs, as fluid power spin drilling tool, impulse oscillation drilling tool etc., though can produce vibrating effect, but all have shortcomings such as anti-impact is lost ability, the life-span is short, impact force is little, these shortcomings have restricted its practical application at the scene, can't reach the purpose of promoting the use of.
The utility model content:
In order to solve existing technical problem in the background technology, it is a kind of under the drilling fluid drilling condition that the utility model provides, the vibratory drilling instrument that abrasion-resistance is strong, the life-span is long, impact force is big.
The technical scheme that the utility model adopted is: moushroom valve formula churn drill well tool, comprise rotor, moushroom valve, joint, tup, cylindrical shell, drill bit, coupling bar, wherein an end of coupling bar is fixedly connected with the two with screw after inserting in the rotor, the other end inserts successively in moushroom valve and the joint and with bolt and is connected, and the loam cake and the sidewall of described moushroom valve overcoat are respectively equipped with through hole; Described upper end of joint is along circumferentially evenly being provided with three through holes, and sidewall has two through holes; Tup inserts in the joint inner chamber, and the tup outer wall contacts with the sealing of joint internal chamber wall, and tup can slide along inner chamber; Joint and cylindrical shell screwed connection, the other end of cylindrical shell is connected with the drill bit spline, and drill bit has up and down stroke, and drill bit is provided with two oblique through holes.
The utlity model has following beneficial effect: the moushroom valve formula churn drill well tool that the application is related, utilize rotor to drive the pressure differential that moushroom valve opens or closes generation, realized vibratory drilling; This instrument does not have spring and rubber parts in forming, and does not have the unexpected shutoff of liquid stream, so abrasion-resistance is strong, long service life; Can obtain enough big impact force by the quality of regulating tup, improve efficiency of breaking rock, and have the function that prevents that sky from beating, the fine protection drilling tool of energy; Instrument integral body is full irony design, has very strong impact force.
Description of drawings:
Fig. 1: the utility model structural representation.
Fig. 2: the C-C sectional drawing among Fig. 1.
Oblique through hole 61 on rotor 1, moushroom valve 2, joint 3, tup 4, cylindrical shell 5, drill bit 6, coupling bar 7, moushroom valve overcoat loam cake through hole 21, moushroom valve sleeve side wall through hole 22, upper end of joint through hole 31, joint sidewall through hole 32,33, the drill bit.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, moushroom valve formula churn drill well tool of the present utility model mainly comprises rotor (1), moushroom valve (2), joint (3), tup (4), cylindrical shell (5), drill bit (6), coupling bar (7), it is fixedly connected with the two with screw that wherein an end of coupling bar (7) inserts in the rotor (1) back, and the other end of coupling bar (7) inserts successively in moushroom valve (2) and the joint (3) and with bolt and is connected; In conjunction with shown in Figure 2, the loam cake of moushroom valve (2) overcoat and sidewall are respectively equipped with through hole (21,22), and joint (3) upper end edge circumferentially is evenly equipped with three through holes (31), and as the flow channels of drilling fluid, sidewall has (32,33) two through holes; Tup (4) is installed in joint (3) inner chamber, and tup (4) outer wall contacts with the sealing of joint (3) internal chamber wall, and tup (4) can slide along internal chamber wall; Joint (3) and cylindrical shell (5) screwed connection, the other end of cylindrical shell (5) is connected with spline with drill bit (6), and drill bit (6) has up and down stroke, and runs through two oblique through holes (61) on the drill bit (6).
The course of work of moushroom valve formula churn drill well tool is: rotor (1) constantly rotates under the drilling fluid hydraulic action, drives moushroom valve (2) and opens or closes.When not giving drill bit (6) pressurization, drill bit (6) is at the spline dead point, and promptly drill bit (6) upper end contacts with the spline end face.Under the drilling fluid effect, rotor (1) rotates, when hole 32 is opened when closing in hole 22, P1=P2, P2＞P3 makes the descending strike drill bit of tup (4) (6) make drill bit (6) by the descending vibration of spline stratum, when tup (4) via hole 33 under the pressure of the drill, P2=P3 tup (4) does not move, when hole 22 is closed, when open in hole 32, P3＞P2, P2=P4, tup (4) is up, tup when covering hole 32 (4) stop motion, drill bit (6) is got back to the spline bottom dead centre, and moushroom valve (2) constantly opens or closes under the effect of drilling fluid like this, promptly realize moving up and down of tup (4), realized the constantly effect on jarring stratum of drill bit (6).Rotor speed is controlled at 720～1000 rev/mins, and tup can satisfy the reciprocating motion of actual needs; Adjust hole 22, the size in hole 32 and the quality of tup, can determine the impact force of tup, impact, thereby reach the purpose of vibratory drilling to satisfy broken rock to drill bit.
