The article considers equipment package for applying technology of thermal-gas-chemical pay zone treatment using binary mixtures. The main advantages of the new technology are shortly described. The authors made an analysis of the main disadvantages of traditional universal equipment for performing of the thermal-gas-chemical simulation method using binary mixtures. Typical arrangement scheme of such equipment at the oil field is given. The basic principles and problems in the design of the pilot technological installations thermal-gas-chemical simulation method using binary mixtures are considered. The composition of designed and manufactured fleet for thermal-gas-chemical pay zone treatment and its characteristics are presented. The typical arrangement scheme of pilot equipment at the oil field is given. The main advantages of pilot equipment are argued. The main tasks are formulated that were solved in the design of equipment package for thermal-gas-chemical pay zone treatment using binary mixtures. The design took into account the features and disadvantages identified during the two stages of the pilot tests. Basic differences of equipment package from the pilot fleet, its advantages and the features are shown. The main characteristics of automation equipment, automated process control systems are provided, the view of the control panel (mnemonic diagram) of the pump unit UN-01 is given. The conclusion is made, that designed equipment package can be implementing in the oilfield operators practice.
