The method of electromagnetic survey design

摘要

A kind of design controlled source electromagnetic survey is a kind of to distinguish the depth edge interest reservoir (2) limited and to specify false positive resistivity structure related (3,4,5). Each of reservoir model and false positive model construct false positive situation. The false positive model of resistivity can be adjusted, and provide the forward model of electromagnetic data reservoir model similar enough, when any difference falls in model kernel. A kind of kernel discrimination rate (referred to as " NSDR ") definition, such as set as peak value normalization two correlation modeling electromagnetic field datas of difference. A kind of region overlay shows that NSDR values (6) allow to determine the additional data, and when needing to distinguish in prosthese, planning of survey is developed correspondingly (7). The quantity influence area covering display for reducing variable is main method.
