    摘要: A system and method for displacing instruments in a pipe having a portion thereof which is greatly inclined to the vertical. The system comprises in combination: a set of instruments mechanically linked to a first end of an electrically-powered displacement device, a semi-rigid composite rod that can be wound round a drum and at least one electric conductor. The method includes advancing the displacement device using the rod uncoiling from the drum. The system and method is of special use in inclined oil wells.

    摘要: A system for displacing instruments in a pipe including a portion that is greatly inclined to the vertical. The system includes a set of instruments mechanically linked, by means of an extension, to a first end of electrically-powered displacement device. The extension is a section of a composite, semi-rigid rod that can be wound around a drum and comprises at least one electric conductor. The present invention also relates to a method for implementing the system. Application is to greatly inclined oil wells and to lateral holes.

    摘要: A downhole device, adapted for use in wireline or slickline application, is provided for incorporation into a downhole string and movement in a wellbore. The device comprises means to orient the device in a wellbore, and one or more conveying means arranged to engage the inner surface of the wellbore and reduce the frictional coefficient. It may also incorporate an eccentric weight and/or a vibrator.
