ACTUATING DEVICE ASSOCIATED WITH A DRILLING TRIM AND COMPRISING A HYDROSTATIC CIRCUIT IN A DRILLING FLUID, METHOD OF ACTUATION AND THEIR APPLICATION.

摘要

The present invention relates to a remote device actuating device (3) associated with a drill string (1) by hydraulic means (10; 53, 58) of displacement cooperating with distribution means (7; 25,26,27; 47) associated with the drilling fluid. BR/ - The displacement means of this device directly transform the hydraulic energy of the drilling fluid mechanical energy actuation without the cooperation of other fluid that the drilling fluid. BR/ - The invention also relates to an actuation method using the device. BR/ - Application to directional drilling in the oil field. / P
