Abstract:

The process of oil producing well operating results over time in unavoidable clogging of bottom-hole zone, which greatly reduces the flow rate. A large number of ways to deal with accumulated deposits has been developed. Reaction binary mixture feeding into the reservoir is of scientific interest and one of the perspective methods. Chemical reaction flowing in the reservoir in the remote zone from the hole bottom leads to sensible rise in the temperature and, consequently, removal of high viscosity fluids and waxes. In this paper, the mathematical model of the motion of a binary mixture in view of the exothermic reaction and phase transition of paraffin waxes into liquid states is proposed.
