Abstract
Correctly constructed lithofacial models of productive deposits, which confirm the distribution of effective thicknesses calculated through the dynamic parameters of the seismic field, significantly reduce investment risks during exploration drilling. The main information used to construct lithofacial models is based on a qualitative analysis of the dynamic parameters of the seismic field – seismofacial analysis and analysis of dynamic attributes (amplitude, frequency, etc.). The article shows the experience of combining facies types of well sections with the results of interpretation of dynamic parameters of the seismic field using the example of continental sediments of one of the layers of the Tyumen formation. These materials show how the selected seismic classes with a certain shape of the route correlate with the facies types of core sections and GIS (geophysical well survey). It is shown that each facies type of section, consisting of genetically different facies-collectors and non-collectors, in the field of dynamic parameters of the seismic field is characterized by certain anomalies of amplitude and frequency attributes. This is also reflected in the area distribution of sections dominated by sandy, clay or carbonaceous lithotypes of rocks on cubes of synchronous acoustic inversion (Pimp, Simp, Vp/Vs).
