SYSTEM AND METHOD FOR DETERMINING AN ORIENTATION OF RESERVOIR GEOBODIES FROM UNORIENTED CONVENTIONAL CORES |
摘要 |
<p>A system and method for determining an orientation of a reservoir feature from an unoriented core. The method includes selecting an arbitrary inclined plane in a longitudinal or transverse cross sectional CT scan image of the unoriented core; flattening the inclined plane by realigning all voxels within a volume of the unoriented core so as to obtain a horizontal plane in a realigned core; selecting a transverse cross sectional CT scan image of the realigned core where a desired feature is present; determining a correcting angle to be added to an angle of a flat-bed contact plane of the realigned core relative to a reference mark in the realigned core to obtain a correct inclination angle relative to compass map coordinates; determining a first angle between a direction perpendicular to the feature relative to the reference mark; and determining a second angle by adding the correcting angle to the first angle.</p> |
