The article has an example of countouring reef constructions by using changing of wave pattern with seismic facies analysis in the area of the Timano-Pechora region.
During many years the major task of seismic researches was studying a relief of basic reflecting borders. Today with the advent of and development of new methodic technological decisions, introduction of powerful high-speed computer complexes, fast rates of growth amounts of works 3D before seismic- explorer the problem is construction of detailed geological model of the area displaying internally a structure of sedimentary objects is put. Now already at a search stage it’s necessary to know such parameters of environment, as porosity, sedimentology, fluid-saturation. Construction of the fullest model of environment provides planning the optimum scheme of development deposits and reduces risk at explorative drilling. Most effectively problems of forecasting specified petrophysical characteristics of a geological section are solved according to seismic prospecting on the basis of the analysis seismic attributes, wave inversion, the AVO-analysis.
