SUBSTANCE: according to measurement results there defined is medium conductivity based on surveillance basic system. On the basis of the received data there made is preliminary 3D-model for which there performed is 3D-calculation and calculation of mistie in relation to measurement data, excluding false inhomogeneities and selecting 3D-objects with epicentres in the points of surveillance basic system.
As a result there received is precise 3D-model and there defined is the location of conduction anomalies in target horizons. There performed are additional measurements by profiles that go through the centres of specified anomalies and there defined is the mistie for the present precise 3D-model that is corrected. As a result conduction anomalies in target horizon are either approved or disproved and their parametres are defined.
There estimated the lateral dimension of the revealed anomaly and in case of its significant influence there performed are the measurements by profiles that go through anomalies' centres. Using the data of the received surveillance system including surveillance basic system and said additional profiles there performed is 3D-inversion. As a result there obtained is final geoelectric 3Dmodel of the examined medium.
EFFECT: improvement of invention geophysical forecast authenticity by way of separating the influence on measurement results of side and deep inhomogeneities. 12 cl, 12 dwg
