METODO PARA ELIMINAR LA INFLUENCIA DE LA MAGNETIZACION DE LA SARTA DE VARILLAS DE PERFORACION EN LA MEDICION DEL AZIMUT EN UN POZO DE SONDEO |
| 摘要 |
<p>The influence of drill string magnetization on an azimuth measurement in a borehole by means of a magnetometer package included in a drill string having a longitudinal axis is eliminated by first eliminating the influence of the cross-axial components of the drill string magnetization through magnetometer readings at various angular orientations of the drill string, and then eliminating the influence of the axial component of the drill string magnetization.</p> |
