Abstract
The article is devoted to improving the technology of effect the oil reservoir and the bottomhole zone of production and injection wells. Based on laboratory experimental studies, a new technology that allows increasing oil displacement from a porous medium, as well as increasing well productivity has been developed. The composition of the proposed composition includes a strong oxidizing agent, low and trihydric alcohols, surfactants, etc. When the components of the composition interact, an exothermic reaction occurs, as a result of which a large amount of heat and gas are released in the bottomhole zone. Due to the released heat, the viscosity of heavy oil components, deposited in a porous medium and worsening the filtration characteristics of the formation, decreases. As a result of the impact of the composition, the permeability of the bottomhole zone, the productivity of production and injectivity of injection wells increase. Since the exothermic reaction takes place in the formation itself, this allows increasing the thermal effects.
