Abstract
The invention provides a hydraulic jet type impactor and belongs to the field of petroleum drilling, mineral exploitation well drilling and geological exploration. A storing mechanism is additionally arranged between a piston rod and a cylinder body of the hydraulic jet type impactor, so that the kinetic energy in piston return stroke can be converted into static energy stored into the storing mechanism. By adopting the hydraulic jet type impactor, impact power of the stroke is enlarged, return stroke energy dissipation is avoided, impact of the piston rod to the rear end part of the cylinder body is relieved, and the service life of the jet type impactor is prolonged.
Description
Technical field
The invention belongs to oil drilling, mineral exploration and exploitation drilling well and geological exploration field, be specifically related to a kind of jet flow type shocker that surges.
Background technology
The drilling technology that spins can effectively improve the rate of penetration of brittle formation, and hydraulic impacter is to realize spinning a kind of well dynamic instrument of drilling technology, as the core component of the drilling well of spinning, hydraulic impacter is to the effect decisive role of the drilling technology that spins.Compare with air hammer, present hydraulic impacter is not owing to there is energy storage device, in the impactor course of work, and the backhaul energy dissipation, the stroke energy shortage causes the jet flow type shocker single strike work not high, can not form effective volumetric fracture to rock.In addition, existing jet flow type shocker test and practical effect analysis are being found, cylinder interior upper surface and piston-rod end all have tangible zap pit trace, device premature failure easily impacts, carried out necessary heat treatment though add man-hour in cylinder ends and piston rod, hardness is very big, and tangible impact vestige is still arranged, illustrate that the backward stroke of the piston end of a period still has very big impact end speed, does not just have extra mechanism to utilize this energy at present.
Summary of the invention
The objective of the invention is to solve a difficult problem that exists in the above-mentioned prior art, a kind of jet flow type shocker that surges is provided, can utilizes the disadvantageous impact energy of backhaul, additional being increased in the impact process, improve the single strike work of impactor, and reduce the premature failure of impact device cylinder body.
The present invention is achieved by the following technical solutions:
A kind of jet flow type shocker that surges comprises cylinder body and piston, it is characterized in that, between the piston rod of the piston of the described jet flow type shocker that surges and cylinder body stored energy mechanism is housed; Described stored energy mechanism adopts spring.
Compared with prior art, the invention has the beneficial effects as follows: the backward stroke of the piston energy is temporarily stored by stored energy mechanism, when piston stroke, storage power is discharged, increased the ballistic work of stroke like this, avoid the backhaul energy dissipation simultaneously, slow down the impact of rear end of the cylinder block portion of piston rod team, prolonged the application life of jet flow type shocker.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is the structure chart of device provided by the invention
The specific embodiment
As shown in Figure 1, a kind of jet flow type shocker that surges comprises cylinder body and piston, it is characterized in that, between the piston rod of the piston of the described jet flow type shocker that surges and cylinder body stored energy mechanism is housed; Described stored energy mechanism adopts spring.
In the described jet flow type shocker that surges, top connection 1 is connected with outer shell 10, jacking mechanism 2 be positioned at upper press cover 9 above.Upper press cover 9 cooperates with fluidic 3, be positioned at fluidic 3 above.Fluidic 3 cooperates with cylinder body 4, be positioned at cylinder body above.Stored energy mechanism 5 is between cylinder body and piston.Lower cover 6 is between cylinder body 4 and center tap 12, and block stamp 8 cooperates with piston 7, be positioned at piston 7 below.
The forced vibration frequency of described stored energy mechanism is identical with element frequency.The rigidity of spring is decided by element switching time and spring life.
Technique scheme is one embodiment of the present invention, for those skilled in the art, on the basis that the invention discloses application process and principle, be easy to make various types of improvement or distortion, and be not limited only to the described method of the above-mentioned specific embodiment of the present invention, therefore previously described mode is preferably, and does not have restrictive meaning.
Claims (1)
