Above-mentioned lateralog electrode system protective sleeve, the upper bottom surface of described backing is provided with the first stopper slot and the second stopper slot, and the edge, lower end of described box body side elevation is located at described second stopper slot, and the lower end of described logging instrument electrode is located in described first stopper slot.
Above-mentioned lateralog electrode system protective sleeve, described through hole is located on the upper box wall of described box body.
Above-mentioned lateralog electrode system protective sleeve, described box body is fixedly connected with the lower end of auxiliary cable.
Above-mentioned lateralog electrode system protective sleeve, the side elevation of described backing is provided with mounting groove, and described mounting groove is uniformly distributed along described backing circumference, and described roller is arranged in described mounting groove.
Above-mentioned lateralog electrode system protective sleeve, at described roller in the radial direction: the length that described roller is exposed at outside described backing side elevation is less than the radius of described roller shaft and is greater than 0cm.
Above-mentioned lateralog electrode system protective sleeve, described box surface is provided with elastomeric layer.
The beneficial effects of the utility model are:

Detailed description of the invention
For clearly demonstrating the scheme in the utility model, providing preferred embodiment below and being described with reference to the accompanying drawings.
As illustrated in fig. 1 and 2, the utility model lateralog electrode system protective sleeve, comprises backing 1, box body 2 and roller 3, and described box body 2 is the uncovered box body 2 in bottom, and the box wall of described box body 2 is provided with the through hole 5 for hanging logging instrument electrode 4 hawser 6 and passing through; Described logging instrument electrode 4 is located in described box body 2, and described box body 2 is located at above described backing 1, and the side elevation of described backing 1 is provided with described roller 3, and described roller 3 rotation direction is identical with wellhole axial direction; The lower end of described hawser 6 is fixedly connected with described backing 1 with described logging instrument electrode 4 respectively through described through hole 5; Described logging instrument electrode 4 communicates to connect with the lower end of the communication cable through described through hole 5.Wherein, described through hole 5 is located on the upper box wall of described box body 2.
Wherein, the upper bottom surface of described backing 1 is provided with the first stopper slot 9 and the second stopper slot 10, and the edge, lower end of described box body 2 side elevation is located at described second stopper slot 10, and the lower end of described logging instrument electrode 4 is located in described first stopper slot 9; Described box body 2 is fixedly connected with the lower end of auxiliary cable 7; The side elevation of described backing 1 is provided with mounting groove, and described mounting groove is uniformly distributed along described backing 1 circumference, and described roller 3 is arranged in described mounting groove; At described roller 3 in the radial direction: described roller 3 length be exposed at outside described backing 1 side elevation equals 1/2 of the radius of described roller 3 axle; Described box body 2 surface is provided with elastomeric layer 8.
In the present embodiment, described backing 1 adopts hard metal to make, described logging instrument electrode 4 is being transferred to the process in wellhole as described logging instrument electrode 4 provides enough protections to make described backing 1, and the described elastomeric layer 8 on described box body 2 external surface produces cushioning effect to the rock slag dropped on described box body 2 etc., avoid rock slag directly to pound causes described box body 2 impaired on described box body 2, and then avoid described logging instrument electrode 4 impaired, and described box body 2 can also be protected the tie point of described logging instrument electrode 4 and communication cable, this tie point is avoided to be subject to the shock of rock slag and to occur loosening, and then avoid the well logging caused because tie point loosens unsuccessfully to occur.Described first stopper slot 9 then avoids the lower end of described logging instrument electrode 4 carrying out occurring in well logging significantly swinging; and described roller 3 is not only conducive to the utility model transfers in wellhole; more avoid described logging instrument electrode 4 lower end to occur significantly swinging; thus avoid described logging instrument electrode 4 to cause the damage of described logging instrument electrode 4 because of multiple impact wellhole inwall, for described logging instrument electrode 4 provides available protecting.
In use process of the present utility model, described logging instrument electrode 4 is fitted together according to Fig. 1 with the utility model, then by described hawser 6, described logging instrument electrode 4 is transferred to treating in well logging wellhole together with the utility model, when described logging instrument electrode 4 is transferred to after well logging section, be advisable described box body 2 being carried expose completely to described logging instrument electrode 4 and normal well logging can be carried out with described auxiliary cable 7, then continue to treating to transfer described logging instrument electrode 4 in well logging wellhole, under the protection of described backing 1, described logging instrument electrode 4 all there will not be radially wobbling by a relatively large margin in whole decentralization process, also just avoid described logging instrument electrode 4 lower end or upper end clash into borehole wall and cause described logging instrument electrode 4 to damage, thus solve logging instrument electrode 4 described in nutural potential logging process occur because of multiple impact borehole wall damage problem.
Above-described embodiment is only for clearly illustrating that the utility model creates example, and not the utility model is created to the restriction of detailed description of the invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All within spirit of the present utility model and principle any apparent change of extending out or variation be still in the utility model and create among the protection domain of claim.
