IMPROVEMENT OF THE LEVEL OF CONTROL AND MONITORING OF THE RESERVOIR PRESSURE MAINTENANCE SYSTEM THROUGH CREATION OF THE UNIVERSAL MODEL

Abstract

The waterflooding process is provided by the technical hydraulic system (THS) of reservoir pressure maintenance, including water intake facilities, treatment systems, pumping stations, pipeline network, shut-off and throttling valves, wellhead equipment of injectors, drained (by boreholes) and flooded (by injection wells) zones of the formation or the system as a whole. The obvious THS interconnection with the productive strata system required a creation of the THS model and the model of productive strata hydraulic system, which should be integrated into a comprehensive model. In the sphere of simulation of hydraulic systems at present there is no theoretical basis formed for building unified hydraulic models related to productive strata systems. Also, there is no unified approach to the mathematical and algorithmic description of models of hydraulic systems with arbitrary properties of elements, due to which the created models and their software implementations are used exclusively in the industry context with large restrictions on description of the properties of the system elements and the boundary conditions.
