Key words: field, the equilibrium model of the geological, water contact, well
As a result, a detailed analysis of materials of geophysical research cuts holes in objects AS9-11 one of the largest oil and gas fields in Western Siberia, established that the existence of a common gas cap in a single reservoir, as well as in adjacent layers may exist with different units and gas-oil-water contacts. The levels of contact blocks, as well as the thickness of the oil rims are functionally related to each other, which follows from the requirement of equilibrium of the system. This can explain the diversity of levels of contact layers AS9-11 in the deposit area. An equilibrium model of the geology, which is the base for building a digital three-dimensional geological and technological model of the object AS9-11.
