Thermohydrodynamic investigations of vertical wells operating in multilayer reservoirs

Authors: R.S. Khisamov, R.G. Farkhullin (Tatneft OAO, RF, Almetyevsk), M.Kh. Khairullin, M.N. Shamsiev (Institute of Mechanics and Engineering, Kazan Science Center of RAS, RF, Kazan), E.R. Badertdinova, V.R. Gadilshina (Kazan (Volga Region) Federal University, RF, Kazan)

Key words: thermohydrodynamic investigations, vertical wells, multilayer reservoirs.

A mathematical model is constructed to describe the thermohydrodynamic processes in "vertical well - multilayer reservoir" system. A new approach to estimate the filtration parameters and flow rates of interlayers is proposed. The curves of the bottomhole temperature variations taken after the bringing the vertical well into production are used as the source data.
