ABSTRACT: Applications,
theoretical analysis and numerical methods are introduced for the simulation of
mechanical models and principles of the porous flow in high temperature, high
salt, complicated geology and large-scale reservoirs in this paper. Considering
petroleum geology, geochemistry, computational permeation fluid mechanics and
computer technology, we state the models of permeation fluid mechanics and put
forward a sequence of implicit upwind difference iteration schemes based on refined
fractional steps of the upstream, which can compute the pressures, the
saturation and the concentrations of different chemistry components. A type of
software applicable in major industries has been completed and carried out in
numerical analysis and simulations of oil extraction in Shengli Oil-field,
which brings huge economic benefits and social benefits. This software gives
many characters: spatial steps are taken as ten meters, the number of nodes is
up to hundreds of thousands and simulation time period can be tens of years and
the high-order accuracy can be promised in numerical data. Precise analysis is
present for simplified models of this type and that provides a tool to solve
the international famous problem.
