The technical solution of the utility model: a kind of integrated annulus logging instrument of crossing.Comprise outer tube and field joint; Field joint is provided with eccentric electric machine assembly installing hole and test plug installing hole, in the electric machine assembly installing hole electric machine assembly is installed; In the test plug installing hole test plug is installed; Outer tube sleeve is tightly connected with field joint outside electric machine assembly and test plug; In the outer tube of electric machine assembly afterbody circuit board is installed, circuit board is connected with test plug by the communication bus that runs through electric machine assembly one side.
Above-mentioned integrated the mistake in the annulus logging instrument is provided with circuit board support in the described outer tube, and circuit board support is connected with circuit board.
Aforesaid integrated the mistake in the annulus logging instrument is provided with electric machine support in the described outer tube, and electric machine support is connected with electric machine assembly.
Aforesaid integrated the mistake in the annulus logging instrument, described circuit board support is connected with electric machine support through connecting pin.
Aforesaid integrated the mistake in the annulus logging instrument, described integrated the mistake in the annulus logging instrument is provided with sealing device in described electric machine assembly installing hole and the test plug installing hole.
Compared with prior art, the utility model has improved maintainability and the assembly process process of crossing the annulus logging instrument owing to adopted technique scheme.By the shirtsleeve operation step, just motor, wiring board etc. can be taken apart, safeguard and overhaul; Solved the problem of installing side by side of motor combination and internal communication bus under the minor structure size, can realize the direct-reading control of motor and drive; Motor assembly is built-in with high-temperature electric machine and multi-stage speed-reducing mechanism, and maximum output torque can reach more than the 0.45Nm, thereby has realized the effect of small machine big (moment) output, has satisfied the functional requirement of instrument under the mal-condition of down-hole.Electric motor mounting structure of the present utility model is applicable to the occasion of conventional oil, water well test.
