RESERVOIR NAVIGATION USING MAGNETIC FIELD OF DC CURRENTS |
摘要 |
<p>A method and apparatus for steering a drilling assembly within a reservoir of an earth formation is disclosed. The drilling assembly is positioned within the reservoir between a conductive upper layer having a DC magnetic field and a conductive lower layer having a DC magnetic field. A sensor of the drilling assembly measures a magnetic field in the reservoir resulting from the DC magnetic field of the conductive upper layer and the DC magnetic field of the conductive lower layer. A processor uses the measured magnetic field to steer the drilling assembly within the reservoir.</p> |
