Description
Technical field:
The utility model relates to a kind of bumper jar, especially at a kind of hybrid drilling jar of mechanical-hydraulic that is used in the drilling operation course.
Background technology:
In drilling process, because drilling assembly is grown reasons such as (being generally 2000 meters to 6000 meters), underground geological condition complexity, technical measures are improper, bit freezing takes place in drilling process drilling tool is inevitably, uses bumper jar can reach the purpose of jarring releasing.
The instrument that is used for jarring releasing at present all is single mechanic jar or hydraulic shock device, and all there is weak point in the two: mechanical drilling jar jarring tonnage is limited and can not realize multiple tonnage jarring simultaneously; And the fluid pressure type bumper jar can be realized the large-tonnage jarring, and at different stressing conditions, can take different jarring tonnages, but the fluid pressure type bumper jar is when jarring, owing to carry in the drilling tool process without any retaining mechanism, be easy to generate the mistake jarring, thereby do not reach the purpose of jarring releasing last.And unavoidable in actual applications because hydraulic system or mechanical reason is unreliable causes inefficacy, thereby do not reach the purpose of jarring releasing.
The utility model content:
The purpose of this utility model is: a kind of mechanical hydraulic-pressure type drilling jar is provided, and it is reliable that it is used, and can reach the purpose of good jarring releasing.
The utility model is to constitute like this: it comprises axle (1), the slips axle (5) that can be threaded with top rod, axle (1) is connected with spline urceolus (2), on spline urceolus (2), be connected with connector (4), slips axle (5) is located between axle (1) and the last connector (4), be provided with slips urceolus (7) in the bottom of last connector (4), slips urceolus (7) is connected with down connector (14), pressure body (15) links to each other with following connector (14), is provided with to prolong axle (16) on slips axle (5).
Between slips axle (5) and slips urceolus (7), be connected with cover (12) in upper slips seat (8), slips (9), lower slips seat (10), dish spring (11), the adjusting, regulate overcoat (13); Be provided with piston (17) in the bottom that prolongs axle (16), be provided with hydraulic valve assembly (18) between connector (14), pressure body (15), the prolongation axle (16) down; Between axle (1) and spline urceolus (2), be provided with three and open watt (3); Between axle (1) and last connector (4), also be provided with jarring pad (6); On spline urceolus (2), slips urceolus (7), following connector (14), pressure body (15), be equipped with oil stifled (19); Between axle (1) and the spline urceolus (2), prolong between axle (16) and the following connector (14), be equipped with potted component (20) between piston (17) and the pressure body (15).
The utility model integrates single mechanical type drilling jar and fluid pressure type drilling jar, has the function of mechanical jarring and hydraulic pressure jarring concurrently, therefore use more safe and reliable, and simple in structure, be easy to dismounting, easy to maintenance; Simultaneously increase by a hydraulic valve assembly, utilize it effectively to ensure the sealing of hydraulic system, can avoid the mistake jarring at hydraulic part.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: the utility model mainly is made up of inside and outside two parts, and inner body has axle 1, slips axle 5, prolongation axle 16, the piston 17 that can be connected with the top drilling tool; Exterior part has the pressure body 15 that can be connected with lower drilling tool, following connector 14, slips urceolus 7, goes up connector 4, spline urceolus 2.Inside and outside two parts utilize potted component 20 to form a sealed volume, stores hydraulic pressure oil, the important component part that constitutes as whole hydraulic system during for jarring.
Between slips axle 5 and slips urceolus 7, be connected with cover 12 in upper slips seat 8, slips 9, lower slips seat 10, dish spring 11, the adjusting, regulate overcoat 13, utilize the mechanical property of upper slips seat 8, slips 9, lower slips seat 10, dish spring 11 to make up machine power partly, constitute the safe locking mechanism device by upper slips seat 8, slips 9, lower slips seat 10, add dish spring 11 and make that the locking mechanism device is more safe and reliable, need overcome the resistance that the locking mechanism device produces when utilizing drill string to stretch, make acting on of mechanical jarring produce.Be provided with hydraulic valve assembly 18 between connector 14, pressure body 15, the prolongation axle 16 down, utilizing down, connector 14, pressure body 15, prolongation axle 16, the hydraulic cavities of piston 17 and the combination of hydraulic valve assembly 18 constitute hydraulic system structure of the present utility model, and, can avoid artificial upper and lower jarring with the effectively sealing of guarantee hydraulic system of hydraulic valve assembly 18.Between axle 1 and spline urceolus 2, be provided with three and open watts 3, utilize three to open watts 3 mechanical property and guarantee that spacing axle 1 and the spline urceolus 2 of making keeps coaxial; Between axle 1 and last connector 4, also be provided with jarring pad 6, when upper and lower jarring action, play cushioning effect; On spline urceolus 2, slips urceolus 7, following connector 14, pressure body 15, be equipped with oil and block up 19, to avoid the leakage of hydraulic oil.Hydraulic valve assembly 18 adopts coloured softer metals, the roughness on oil cylinder surface is not exerted an influence, thereby guarantee surface roughness in the hydraulic cavities chamber.
On when carrying drilling tool, slip assemblies 9 is subjected to dish spring 11 elastic forces and the coupling mechanism force effect of slips mechanism, forces slips 9 retaining mechanisms to hold slips axle 5 tightly.Overcome the coupling mechanism force and the hydraulic valve assembly 18 of slips mechanism and prolong damping action between the axle 16 when slips axle 5 is up with axle 1, bumper jar will make drill string energy storage, time-delay, hydraulic valve assembly 18 triggers simultaneously, hydraulic oil savings hydraulic pressure energy.Reach when releasing energy when axle 1 is up to constraint relief state, hydraulic valve, the energy of hydraulic oil savings discharges suddenly, and the elastic potential energy that stores in the drill string converts kinetic energy upwards to simultaneously, hits in the generation.The utility model hits on can also producing continuously, only need transfer drilling tool during use and lock again up to retaining mechanism, repeats said process again, will produce to hit on continuous.This utility model is hit in the process last owing to designed specific safety locking mechanism device, in the time of must making pulling force produce coupling mechanism force greater than mechanical interlocking mechanism, hydraulic pressure is partly played a role, thus the harm of effectively avoiding the mistake jarring to bring.
When pressing down drilling tool, axle 1 is descending, drill string is stretched, need overcome the resistance that the locking mechanism device produces, and exert pressure to bumper jar, when the suffered pressure of bumper jar surpass safe locking mechanism following when hitting releasing force, drill string begins free-falling, strong jarring force just will affact the drill string part of being blocked, and make stuck point loosening.
Cover 12, spinning of overcoat 13 of adjusting in regulating are regulated (add large-tonnage when outwarding winding, dwindle tonnage when screwing), can reach the jarring requirement of required tonnage.
