Abstract
The utility model relates to a drilling column shock absorber used for oil and natural gas drilling tool, comprising a spline mandrel 1, a spline cylinder 2, a spring group 4, a piston 6, etc. The spline mandrel 1 is connected with the spline cylinder 2, the spline cylinder 2 is connected with a base joint 3, the spring group 4 is arranged in the spline cylinder 2, the terminal of the spring group 4 is provided with a regulating ring 5, the terminal of the regulating 5 is provided with the piston 6. The working characteristics of the drilling column shock absorber can not change with the increasing of the wear for using the metal spring or nonmetal spring, also at the same time the working characteristics of the drilling column shock absorber can not be effected by the working environment such as the bottom hole temperature, etc. The deformation energy of the drilling column shock absorber is greater than the liquid spring, thus the shock absorber can both have cushioning effect in the two directions of pressure and tension.
Description
The utility model is to be used for the petroleum and natural gas drilling tool, promptly a kind of drill-string shock absorbers.
Drill-string shock absorbers mainly is made up of torque-transmitting mechanisms, sealing mechanism, spring mechanism etc., be connected during work on a certain section tubing string between drill string and the drill bit, when the operation torque of drill string and work the pressure of the drill are delivered to drill bit, slow down vibrations that the broken rock of drill bit produced and to the adverse effect of drill string.There are some problems in existing drill-string shock absorbers: 1. use with the liquid spring of silicone oil as working media, because silicone oil is relatively more responsive to temperature and other underground work condition, its scope of application is restricted, and for example uses that its service behaviour is affected when deep-well.2. liquid spring is strict to sealing performance, and along with the wearing and tearing of hermetically-sealed construction, damping performance sharply descends in the use.3. depend primarily on the deformation energy of spring owing to the cushioning effect of spring mechanism, and the deformation energy of liquid spring is difficult to control, thereby has influenced the operating characteristic of damper.4. can only compress owing to liquid spring, thereby damper can only have cushioning effect on single direction.
The purpose of this utility model is to provide a kind of and has the moderate finite deformation energy, its operating characteristic is not influenced by working environments such as bottom hole temperature (BHT), and the drill-string shock absorbers of cushioning effect is all arranged on pressure and pulling force both direction.
The utility model is achieved in that and comprises splined mandrel 1, spline cylindrical shell 2, lower contact 3, groups of springs 4, adjustment ring 5, piston 6, splined mandrel 1 with spline cylindrical shell 2 in and with spline cylindrical shell 2 pivot bush units, spline cylindrical shell 2 is connected with lower contact 3, between splined mandrel 1 and spline cylindrical shell 2, groups of springs 4 is housed, piston 6 is arranged in the end of splined mandrel 1.
The utility model also adopts following technical scheme:
The end of groups of springs 4 is equipped with and is adjusted ring 5.
Groups of springs 4 is enclosed within on the splined mandrel 1, and an end of groups of springs 4 withstands on the splined mandrel 1, and the other end of groups of springs 4 withstands on the shoulder of spline cylindrical shell 2 by adjusting ring 5.
Groups of springs 4 can be a disk spring, also can adopt ring spring, also can be rubber spring.
Advantage of the present utility model is: owing to used former liquid spring instead metal spring or nonmetal spring, the operating characteristic of drill-string shock absorbers is not changed with the increase of wearing and tearing, also be not subjected to simultaneously the influence of working environments such as bottom hole temperature (BHT), its deformation energy is greater than liquid spring, and, make damper on pressure and pulling force both direction, cushioning effect be arranged all owing to adopt mechanical spring.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
Form by splined mandrel 1, spline cylindrical shell 2, lower contact 3, groups of springs 4, adjustment ring 5, piston 6 etc., splined mandrel 1 links to each other with upper drilling string, lower contact 3 links to each other with drill bit, the moment of torsion of drill string is delivered to lower contact 3 by the spline on splined mandrel 1 and the spline cylindrical shell 2, and the pressure of the drill of drill string is delivered to lower contact 3 by splined mandrel 1, groups of springs 4 and adjustment ring 5.
It is the working media of spring that groups of springs 4 is different from liquid such as silicone oil, it adopts the big metal springs of deformation energy such as disk spring, ring spring, perhaps nonmetal spring such as rubber spring, its operating characteristic is not subjected to the influence of working environment, and deformation energy is greater than liquid spring.
When drill string and damper were stressed, the shoulder of splined mandrel 1 played cushioning effect from top compression spring set 4; When drill string and damper were subjected to pulling force, splined mandrel 1 from bottom compression spring set 4, played cushioning effect by piston 6.
