The paper presents results of research, the purpose of which is to obtain additional information on the tectonic structure of the pre-Jurassic complex at an oil deposit in Western Siberia, obtained from seismic data in the field of diffracted waves. A complex geological structure and a large number of tectonic dislocaitions characterize the Pre-Jurassic complex within the field. Diffraction imaging is the method of detecting diffractors of wavefield that represent fracture zones, faults and other objects [1]. The main idea of the method is to use diffraction as additional information, which in the method of reflected waves is a noise. The method was used at this oilfield for the first time. As a result of the studies, polygons of the distribution of zones of fracture and tectonic dislocations were obtained.

Materials and methods
Seismic data were obtained from the study area, which is located in the northern part of the Frolovskoye megavasin of Western Siberia. The diffraction imaging method was used.
