COMPLEX ELECTRICAL MONITORING OF SALT KARST PROCESSES

(Kolesnikov V.P. Laskina T.A. )

Predictive dynamic geoelectrical model of sinkholes development has been formed on the base of physical-geological information and analysis of electrical monitoring surveys for investigation of karst processes dynamic in the context of a salt deposit. The main goal of the research is to develop approach and technology of electrical surveys to predict the stages of the sinkhole development processes.......

RELATIONSHIPS BETWEEN PARAMETERS OF GEOPHYSICAL FIELDS USED FOR INTERPRETATION IN REGIONAL OIL AND GAS WORKS

(Genik I.V. )

The analysis of data from regional gravity and seismic surveys in the Perm Territory and the Kirov Region, aimed at clarifying the geological structure of the territories and the discovery of oil and gas prospective structures, is performed. The relationships between the characteristics of geophysical fields used for interpretation are investigated. Relationships between the parameters of seismic structural surfaces and the geological and geophysical data used in the interpretation (relief, magnetic and gravitational fields and their transforms) are established. The possibilities of predicting the results of geophysical work based on the available geological and geophysical information are shown.......

FEATURES OF CONSTRUCTING A VELOCITY MODEL FOR DEPTH MIGRATION IN CONDITIONS OF KARST PHENOMENA

(Laptev A.P. Belozerova N.S. Klestov I.M. )

The article describes the problems arising in the construction of a velocity model for the depth migration of seismic data associated with the local velocity heterogeneity of the section. On the area with velocity anomalies related to karst processes, the method of their localization and accounting in velocity model by scanning velocities was reprocessed and tested.......
