FIELD: measurement equipment.SUBSTANCE: invention relates to well logging devices. The device is proposed for step displacement of an accessory around an axis of step displacement, comprising a support for maintenance of an accessory for rotation around the axis of step displacement, besides, the support comprises a rotary fixture maintained on the base, for rotation around the transverse axis crossing the axis of step displacement, and a mechanism of a drive of step displacement of the accessory around the axis of step displacement. Besides, the mechanism of drive of step displacement comprises a master part and a slave part. At the same time the master part is arranged on the base, and the slave part is made on the rotary fixture, and is connected as capable of transferring driving force with the accessory. Besides, the slave part is capable of engagement and disengagement with the master part as the rotary fixture rotates around the transverse axis, by means of which, when the slave part is in engagement with the master part, it may receive a driving force, resulting in step displacement of the accessory around the axis of step displacement. Also the logging device comprising the specified device of step displacement and the logging method using the specified device are disclosed.EFFECT: increased reliability of operation of a device and accuracy of measurements due to elimination of systematic errors of a device.37 cl, 26 dwg |
