| 摘要 |
<p>The invention concerns a method for detecting an association between a reservoir (12) and a resurgence (14) of fluid to define an underground vein (16) of fluid between the reservoir (12) and the resurgence (14). A first electromagnetic field associated with the reservoir (12) is obtained by electrical excitation according to a first alternating potential, and a second electromagnetic field associated with the resurgence (14) is obtained by electrical excitation according to a second alternating potential. The second alternating potential differs from the first potential in terms of the frequency and/or phase in order to obtain a second electromagnetic field that can be distinguished from the first electromagnetic field. For at least one value of said first electromagnetic field and one value of said second electromagnetic field, which are significantly non zero, measured simultaneously between the resurgence and the reservoir, an underground vein (16) associates the reservoir (12) and the resurgence (14).</p> |
