Annotation:
The article presents an algorithm for calculating reservoir operation modeling taking into account the intrusion of edge waters and changes of the PVT-properties of the fluid. A mathematical model of the process based on the general equation of material balance, Fetkovich and Carter – Tracy analytical functions of the edge waters influx, as well as correlation dependences of the fluid PVT-properties: Standing, Glaso, Al-Marhoun, Petrosky is presented. Based on the obtained mathematical model, testing was carried out on the example of one of the deposits. A comparative analysis of the obtained results with the calculated results of the MBAL software product from Petroleum Experts Company is given.
