Annotation:
To date, thermodynamic studies of wells (temperature logging) have become widespread when solving problems of diagnosing the wells and reservoirs operational state. The heterogeneity (in terms of permeability) of reservoir rocks, the presence of highly-permeable fractures and low-permeable zones of heterogeneity significantly influence the formation of the thermal field. The authors of the article consider the temperature logging application in relation to the determination of heterogeneous reservoirs characteristics, including reservoirs with fractures as well as reservoirs with a fractured near-well zone. The influence of the parameters of the hydraulic fracture (half-length, width, permeability) and the fractured near-wellbore zone (permeability, radius of the near-wellbore zone) on the thermal field formation of the liquid flowing into the well has been studied. The possibility of heterogeneous reservoirs parameters determination by temperature logging in a production well is shown.
