History Matching Problems of Filtration Theory. Complex Adaptative Geological Models of Fields

To choose improved oil or gas field development its necessary to create algorithm providing the possibility to calculate a field development performance during all the period of production for the different controlled influences on the bed. The simulation reliability and therefore the validity of the accepted project decisions depends on the degree of the adequacy of the mathematical models used to real physical processes as well as on the degree of the truthfulness of the initial geological-field information used at the simulation. It is the important peculiarity of the large oil and gas fields that they have common hydrodynamical connection between processes which take place in an aquifer, in a bed, in wells and fluid gathering, compressing, cleaning and treating and field pipeline transferring systems. Therefore to carry out long-term forecast of field development performance it is necessary to create the complex adaptive mathematical model which unites both reservoir and ground technological equipment (GTE) models.
