The radial damping structure is sleeved outside an electronic framework, and comprises a damping loop and a damping ring, wherein the damping loop is provided with at least one damping groove; and the damping ring is sleeved in the damping groove. The radial damping structure can be applied to well logging during drilling instruments adopted in geological prospecting, and the technical effect of reducing or isolating vibration generated by drilling tools can be achieved.
Description
Technical field
The utility model relates to the geological exploration techniques field, especially a kind of radial vibration-reducing structure.
Background technology
Connector for logging while drilling is in when work, and the vibration in the drilling process can be delivered on the inner electronics skeleton, so need to take the measures such as vibration damping, vibration isolation during the electronics frame design.The orientation inserting tube that particularly arranges on the electronics skeleton, the orientation inserting tube is provided with the sensors such as acceleration and fluxgate, and the working space environment is had higher requirement, therefore the electronics skeleton is taked the measures such as vibration damping, vibration isolation to seem particularly necessary.In the course of the work, some corresponding measures have also been taked in order to eliminate as far as possible from the impact of drill string vibration, in connector for logging while drilling, the O RunddichtringO is set between electronics skeleton and urceolus usually eliminates the radial vibration that produces in the drilling process, the structure of namely offering annular groove mounting O-shaped sealing ring at the electronics skeleton is eliminated radial vibration, but this kind design and installation inconvenience, effectiveness in vibration suppression is general.
The utility model content
The technical problem that the utility model solves provides a kind of radial vibration-reducing structure and puts, and can reduce or isolate the vibration from drilling tool.
For solving the problems of the technologies described above, the utility model provides a kind of radial vibration-reducing structure, and described radial vibration-reducing structure is sheathed on outside the electronics skeleton, comprises damping ring and damping ring;
Described damping ring offers at least one vibration damping groove, and described damping ring is sheathed in the described vibration damping groove.
Above-mentioned radial vibration-reducing structure also can have following features: described damping ring external surface evenly is provided with the first vibration damping groove, the second vibration damping groove.
Above-mentioned radial vibration-reducing structure also can have following features: described damping ring is the O RunddichtringO.
Above-mentioned radial vibration-reducing structure also can have following features: described damping ring is semicircular ring.
The utility model such scheme has following beneficial effect:
In the such scheme, the radial vibration-reducing structure is different from the damping ring of electronics skeleton by the selection of material, can realize can reducing or isolate the vibration from drilling tool to the vibration damping between electronics skeleton and protection cylinder, the improvement of vibration isolation measure.

The specific embodiment
In conjunction with Fig. 1 and Fig. 2, connector for logging while drilling comprises the first joint 1, urceolus 3, electronics skeleton 2, middleware 4, the second joint 5; The first joint 1, the second joint 5 are threaded with urceolus 3 respectively, and middleware 4 is placed on urceolus 3 inside, are connected and fixed by screw and the second joint 5; Electronics skeleton 2 is connected with middleware 4.Connector for logging while drilling because the vibration that drilling tool produces is directly imported urceolus 3 into by the first joint 1, is passed to electronics skeleton 2 places through urceolus 3 in the course of the work again.
Such as Fig. 2, usually at electronics skeleton 2 annular groove 7 is set in the prior art, O RunddichtringO 6 directly is installed, eliminate urceolus 3 by O RunddichtringO 6 and transmit the radial vibration of coming, 2 on urceolus 3 and electronics skeleton only pass through O RunddichtringO 6 vibration dampings, therefore effectiveness in vibration suppression is general.
Embodiment one
In conjunction with Fig. 3 and Fig. 4, the radial vibration-reducing structure among embodiment of the utility model comprises damping ring 9 and damping ring 8; The radial vibration-reducing structure is sheathed on outside the electronics skeleton 2.
Adopt in the connector for logging while drilling of embodiment 1, offer wider annular groove 10 at damping body electronics skeleton 2, be used for installing damping ring 9; Offer vibration damping groove 11 at damping ring 9, be used for installing damping ring 8.In the installation process, at first damping ring 9 is enclosed within on the annular groove 10 of electronics skeleton 2.Then the damping ring 8 of elastomeric material being made packs in the vibration damping groove 11, and is simple in structure, easy for installation.
In the course of the work, the vibration that drilling tool produces is passed to urceolus 3 through the first joint 1, is passed to the damping ring 8 that is installed on the damping ring 9 by urceolus 3, is passed to damping ring 9 by damping ring 8, is passed at last in the electronics skeleton 2.Damping ring 8 is made by elastomeric material, and preferably, the damping ring 8 in the present embodiment is the O RunddichtringOs that adopt.The damping ring 9 of the present embodiment is comprised of two semicircular ring, and the material hardness of damping ring 9 is lower than electronics skeleton 2 material hardnesses, and preferably, the material of the damping ring 9 in the present embodiment is polyether-ether-ketone PEEK or copper.Electronics skeleton 2 is generally made by duralumin in the connector for logging while drilling, and the material hardness of damping ring 9 is lower than the material hardness of electronics skeleton 2, has the characteristics of further vibration damping; Compared with prior art, the damping ring 9 made of low-durometer material and the elastomeric material damping ring 8 combination settings of making can have been eliminated the vibration from drilling tool to a great extent.
Embodiment two
Such as Fig. 5, the damping ring 9 among another embodiment of the utility model is different from the damping ring 9 among the embodiment 1, and damping ring 9 external surfaces of the present utility model can arrange a plurality of vibration damping grooves, can adjust the width of damping ring 9 according to needs are set.Damping ring 9 external surfaces among the embodiment one are provided with a vibration damping groove, and preferably, damping ring 9 external surfaces in the present embodiment evenly are provided with the first vibration damping groove 12 and the second vibration damping groove 13.After at the first vibration damping groove 12 and the second vibration damping groove 13 places damping ring 8 being installed respectively, compared with embodiment 1 by the radial vibration-reducing device that two damping rings 8 consist of, can further eliminate the vibration from urceolus 3, make the working environment of electronics skeleton 2 more stable.
Adopt the connector for logging while drilling of above-described embodiment 1 or 2, can effectively lower or isolate in the course of the work the vibration from drilling tool, make the working environment of electronics skeleton more stable.
