Title: Claude Dreuilhe: Innovator in Azimuth Measurement for Non-Vertical Drilling
Introduction
Claude Dreuilhe is a notable inventor based in Saint Ismier, France. He has made significant contributions to the field of drilling technology, particularly with his innovative methods for measuring azimuth in non-vertical drilling applications. His work is essential for improving the accuracy and efficiency of drilling operations.
Latest Patents
Dreuilhe holds a patent for an "Azimuth measuring method for non-vertical drilling." This method involves measuring two components of the magnetic field continuously during the rotation of the drill pipe string. The cylindrical section of the drill pipe string is made from ferromagnetic steel, which is standard in drill pipe fabrication. A magnetometer measures the two components along axes that are perpendicular to the drill pipe's axis. When the gravitational acceleration component reaches its maximum along one of these axes, an accelerometer device triggers the calculation and recording of the ratio of the two magnetic field components. This recorded value allows for the calculation of the azimuth of the drill pipe string relative to magnetic north, facilitating continuous position determination of the drilling tool during curved drilling operations.
