| 摘要 |
<p>The invention concerns a method for characterising the coherence of an environment characteristic measurements, consisting in: taking N types of reference measurements in each observation (Xi) of a reference set; constituting at least a training set with N dimensions containing all said observations (Xi); taking at least N application measurements in each observation (Qi) of an application set; comparing each application observation (x) with all the observations (Xi). The invention is characterised in that it further consists in: constructing for each observation (Xi) a neighbouring domain (Di), said neighbouring domains constituting said training set and an acceptation class (Ca), and defining a degree of appurtenance of the application observations (x) to said acceptation class (Ca). The invention is particularly applicable to the identification of a lithologic facies in an oil field.</p> |
