Аннотация: Model representations are used to analyze the technological process of alternating the appointment of wells. The role of producing and injection wells alternates. The purpose of this technology is to reverse heat fluxes. Changing the direction of heat fluxes is a way to preserve the phase state of frozen soils. The development of hydrocarbon deposits in the extreme north requires the preservation of perennial frozen soils in a solid state. These are safety requirements. In an injection well, it is easier to build a process for injecting refrigerant into the top of the well. When using packers to separate the indicated portion, the process of pumping water to maintain reservoir pressure may continue in the usual manner. Packers are installed on the lower boundaries of frozen soils. Perennial frozen soils are cooled an order of magnitude slower than heating. It is promising to use rock fracturing and faults to penetrate the refrigerant. Normal refrigerants are used. Gaseous refrigerants are preferred. After the heating stage of adjacent rocks, they have increased permeability. The product of thermal reverse uses this circumstance. Refrigerant penetration is simplified. And in turn, it leads to blockage of the formed network of microchannels. The convection method of heat exchange is cut off. The convection heat transfer process is responsible for most of the heat fluxes. A sharp change in heat fluxes occurs immediately after the reverse. The proposed technology allows you to use an additional option for the operation of the existing layout of wells in the oil and gas field. The usual practice of the operation of the fishery may remain without noticeable changes. Using existing gas preparation equipment simplifies the implementation of the technology. © Published under licence by IOP Publishing Ltd.
