Modern ideas about the formation of hydrocarbon deposits are based on the results of experimental and theoretical studies of the lithosphere dynamics. They are based on the established facts of the "instability of fluid systems in the sedimentary cover and foundation, as well as the migration of fluids through the permeable zones resulting from the varying stresses in the earth's crust". It follows that the geological environment is non equilibrium. Forces of external influence and thermodynamic conditions inside the crust promote the extrusion of fluids from the lower horizons to the upper horizons and ensure their movement through the zones of decompaction to the places of discharge, which are often the near-fault zones limited by fluid. The developed technology makes it possible to identify horizons in the context of the geological environment with which hydrocarbon accumulations can be associated, visualize their position in space and, thus, create a basis for the design of the location of wells and solve several problems:
a)Obtain a clear spatial representation of the properties of the geological environment.In particular, the provisions of reservoirs supplying hydrocarbon migration channels,detection of new zones of increased permeability; b)According to the distribution of the parameters of the stress-strain state, it is possibleto obtain a spatial representation of the direction of migration of the fluid flows; c)The notion of the morphology of productive horizons provides a basis for designingwells and allows conclusions about the possible location of new deposits; d)The proposed methodology can be used as one of the stages of prospecting andexploration of hydrocarbon deposits on the projected areas in order to identifyproductive horizons in the crustal section and to assess the possible direction of fluidflows in the block under study; |
