Detailed description of the invention
In order to make those skilled in the art person understand better this practicality invention, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the embodiment of a part of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, should belong to the scope of protection of the invention.
Be below embodiments of the invention one.
The invention provides a kind of pushing device, comprise at least one principal arm, at least one pair of arm, at least one pole plate and tool body, it also comprises at least one group of two plate spring structure;
Described principal arm and described pair of parallel being connected between described pole plate and described tool body of arm; Described pair of plate spring structure is between described principal arm and described pair of arm, this pair of plate spring structure comprises two elastomeric elements, one end of described pair of plate spring structure is connected with described pole plate, the other end is connected with described tool body, and the spacing between described two elastomeric elements is more than or equal to the described arm width of paying.
Wherein, this pushing device is to be opened/closed, and described pole plate for supporting the borehole wall in the time that logging instrument is worked, when oil logging tool is not worked, logging instrument becomes closure state, and oil logging tool is in the time of underground work, make described logging instrument in opened condition by circuit control, pole plate and the borehole wall recline.Spacing between two elastomeric elements of this pushing device is more than or equal to described pair arm width, thereby makes to pay the structural strength that arm has enough placement spaces and can ensure to pay arm.
The pushing device of this embodiment is owing to having adopted two plate spring structures, larger with single plate spring structure phase specific force value of the prior art; And two plate spring structures can symmetry apply power, thereby reduce the pole plate power that swings, the power that reclines symmetry, this is more stable than the reinforcing placed in the middle of single plate spring structure.Meanwhile, the pushing device of this embodiment has also strengthened the recline power value of pole plate to the borehole wall, has improved the measurement quality of instrument; With principal arm, pay an arm pole plate is connected with main body, in only space, place elastic mechanism, make pole plate there is a certain size to the borehole wall, the stable power that reclines, better completes well logging demand.
Be below embodiments of the invention two.
Embodiment bis-comprises a principal arm, one pair of arm, a pole plate and tool body, and one group of two plate spring structure.Described principal arm and described pair of parallel being connected between described pole plate and described tool body of arm; Described pair of plate spring structure one end is connected with described pole plate; The other end is connected with described tool body, and the spacing between described two elastomeric elements is more than or equal to the described arm width of paying.Above-mentioned pushing structure, owing to only having a principal arm, one pair of arm and a pole plate, in during well logging, logging instrument in opened condition, except the borehole wall that reclines of the pole plate in pushing structure, tool body also needs to do braced structures and borehole wall laminating, therefore, and in this case, described tool body can be the arcuate structure identical with borehole wall radian, thereby can stably support together the borehole wall by plates of similar polarity.
