Based on model concepts, the technique of maintaining the stability of the permafrost
layer is analyzed. An injection well is considered as a reference channel for injecting a mixture
of liquid and gas. The purpose of this technology is to control the flow of heat. The development
of hydrocarbon deposits in the extreme north requires the preservation of perennial frozen soils
in a stable solid state. Stable condition of frozen soils is a guarantee of well operability. An
injection well is used to inject refrigerant into the frozen soil zone. When using packers to
separate said portion, the injection process to maintain reservoir pressure may continue in the
usual manner. Permanent frozen soils are conditioned using a mixture of liquid and gas. This
mixture allows you to control the parameters of temperature, pressure and heat capacity over a
wide range. The directions of the mixture are formed using a packer system. Packers are installed
in the tubing and in the annulus. The formation of a coolant agent is organized directly in the
well above the working formation. The technique of ejector pumps is used. The ejector is a
device for controlling the parameters of the mixture. The components of the mixture are fed
through columns (pipes). The organization of the movement of components is considered as an
additional degree of freedom. 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 unchanged.
