Abstract
The oil drilling of a ''shocking and vibration drilling device'', with the technical activity using a non-high-frequency components (clash hammer, slide-valve, etc.), relying on a hydraulic pulse oscillation cavity to produce pulse pressure fluctuation pump, playing a role in pistons to produce the vibration drilling pressure, it solves the short life of the existing drilling tools, and solves the problem of processing and maintenance. Its technical points in the main body of the device is with hydraulic pulse oscillation interior cavity and the pistons by a hydraulic pulse oscillation cavity pulse vibration, in the role of trigger device which produces on the piston fluid fluctuation, so that the pistons have a high-frequency vibration, driving the vibration of the drill, realizing the shock and vibration to drill, the device has a simple structure, long service life, easy maintenance and other advantages so that it can be extensively due to oil drilling site operations.
Description
Technical field:
The utility model relates to " a kind of impact shock drilling rig " that a kind of field drilling is used.
Background technology:
At present both at home and abroad field drilling is generally used the impact shock drilling tool, and it is when rotate with certain speed, with certain vibration frequency drill hammer, makes it impact rock, carries out compound broken rock, the raising bit speed.The vibratory impulse drilling tool of oil drilling application at present mainly relies on the liquid vibration block stamp to move repeatedly, and the block stamp high-frequency high-speed impacts awl (piston), drives drill vibration and drills.Can divide valve formula, jetting type, jet absorption type from promoting the block stamp motion mode.Because vibration is by the realization of moving repeatedly of block stamp high frequency, the mechanism of feasible promotion block stamp motion such as guiding valve, spring, changement etc. very easily damage, cause such drilling tool life-span very short, and instrument complexity, difficult processing, maintenance difficulty, therefore can not satisfy the drilling well requirement, thereby, limited applying of impact shock drilling tool.
The utility model content:
Because moving repeatedly by the block stamp high frequency, vibration realizes drilling well in order to overcome existing drilling well impact shock instrument, the guiding valve of feasible promotion block stamp motion, spring, changement etc. very easily damage, cause very short, difficult deficiency of keeping in repair of drilling tool life-span, the utility model provides " a kind of impact shock drilling rig ", this device design a kind of no high frequency movable part (block stamp, guiding valve etc.), rely on hydraulic impulse vibration chamber to produce the pulse ripple pump pressure, act on piston and produce vibration the pressure of the drill.This device is not only simple in structure but also maintenance is convenient, and long service life has improved bit speed, has accelerated the speed of field drilling exploitation, is convenient to push away application.
The technical scheme that its technical problem that solves the utility model adopts is: adopt hydraulic impulse vibration chamber and piston are housed in this device main body, produce impulse oscillation by hydraulic impulse vibration chamber, act on drilling liquid pressure generation fluctuation on the piston in the initiating device, thereby, make piston produce dither, drive drill vibration, realize the impact shock drilling well.The utility model is by main body, and its upper end has taper drilling rod box thread, and end has common box thread in addition; Main body one end is had taper drilling rod box thread to be threaded with taper drilling rod pin thread in the top connection; Be provided with baffle ring in main body, baffle ring is threaded with main body; Between baffle ring and top connection, be provided with fluid pulse vibration chamber, this vibration chamber mainly contains two kinds of forms: a kind of is the feedback oscillation chamber made from erosion resistance tungsten carbide or tool steel, it is that the feedback oscillation chamber is formed as Fig. 3 by the less upper runner of diameter and lower flow channel and the bigger intermediate flow channel of diameter, it is when fluid passes through with certain speed, feedback oscillation takes place at diameter broad in the middle place, and fluid ejects the back with certain speed and forms pulsing jet; Bistable impulse hunting chamber such as Fig. 4 that another kind is flowed back to the road, descended back pressure chamber, right runner, left runner to form by tubaeform inlet, last back pressure chamber, liquid, it is the bistable pulsing jet element that relies on the fluid wall attachment effect, left and right sides runner alternating spray forms the impulse hunting jet.At main body lower end and piston stop collar by being threaded.In the piston stop collar piston is housed, piston is by " O " type or " Y " RunddichtringO and main body formation slipper seal.Piston can be in main body, up and down in the piston stop collar.Cooperate with piston by the piston stop collar, torque is passed to lower contact, lower contact and piston are with being threaded.Except that the impulse hunting chamber, other component can be made with 35CrMo or 42CrMo.
The beneficial effects of the utility model are, because the utility model is to rely on the hydraulic impulse vibration cavity that the drilling fluid portion of energy is converted into piston impact to vibrate the purpose that realizes drilling well, need not the block stamp impact piston, the parts that take in sail so this apparatus structure is simple, are manufactured easily, maintenance is convenient, reach this device lifetime more than 500 hours, not only the life-span long, and dependable performance.
