METHOD AND DEVICE FOR TAKING MEASUREMENTS AND/OR CARRYING OUT INTERVENTIONS IN A SUBSTANTIALLY INCLINED WELL PORTION AND ITS APPLICATION TO THE ACHIEVEMENT OF SEISMIC PROFILES

摘要

method and device for making measurements and interventions in a portion of the shaft substantially inclined to the vertical or horizontal by means of a set of instruments placed at the lower end of a rigid column. the invention relates to a method for making and seismic profiles.the method according to the invention is particularly characterized in that: the whole is positioned, positioning, or (2) the extension of the column (6) at the lower end of the column, the package (2) is in a first position with respect to the extr in the end, it introduces the whole shaft (1), (2) and the lower part of the column.we do this in the shaft (1) by pushing on the end of the column (6) until it reaches a desired position substantially all free and clear, the whole of the first position.then, in a second position in which it rests on a wall of the well and where it is mechanically decoupled from the column, the connection between the set and the column is performed by a flexible hose, and the measurement is made and / or intervention the device allows for the implementation of the method.the seismic method is characterized in that the measurements are effected in a substantially horizontal so that a tube placed in the surface seismic source is in operation. the invention applies in particular to the actions or interventions that are performed in a borehole on the ground.
