FIELD: geology.
SUBSTANCE: invention relates to methods for geological interpretation of seismic data. Paleochannel is mapped by performing an object-oriented interpretation. Analyze the shape of the bend in a seismic image by fixing the shape of the bend in the form of a curved line. Numerical characteristics of the height of the bend, the length of the bend, the width of the channel formation belt, and the width of the channel are determined. Calculate the coefficient of tortuosity with mathematical calculation. Set the type of river system. Determine the relative width of the channel on the basis of the established type of river system and the width of the meandering belt. Power of the accretionary complex and the thickness of the channel sediments of the established type of the channel system are determined. Choose modern analogues by type of channel process and size of the river. Form recommendations for further study of the paleo-mouth and forecast of development zones for the best collectors.
EFFECT: providing a qualitative forecast of the morphometric parameters of the proposed hydrocarbon deposit.
