Thermal Impact of Reactive Binary Mixture on the Productive Formation

Abstract

The process of exploitation of an oil producing well leads eventually to the inevitable clogging of the bottom hole zone which significantly reduces the flow rate. A large number of methods for combating accumulated deposits have been developed. One of the most promising and of scientific interest is the method of feeding a reactive energy-releasing binary mixture into the reservoir. The flowing chemical reaction in the zone away from the bottom leads to a significant increase in temperature and, as a consequence, removal of highly viscous fluids and paraffins. In this paper, we propose a mathematical model for feeding a reacting binary mixture into a reservoir. The effects of rock heating and gas evolution are taken into account. An example of the thermal effect on the reservoir is given.
