The efficiency of using original highly efficient vertical-axis wind turbines (VA wind turbines) based on N-Darya-Savonius combined rotors (KR) is substantiated for the national parks of southern Russia. Based on experimental studies, the power factor of the original combined rotor with blades having zigzag flaps was first obtained. The maximum values of the power factor of the CR reaches CP = 0.6 exceeding theoretically possible values for horizontal-axis wind power plants CP = 0.59. When working in a wind turbine, there are no emissions of pollutants into the atmosphere, oxygen consumption, thermal pollution, generation of infrasound and noise. VA wind turbines with a power of 1–10 kW, it is advisable to apply for the generation of electric and thermal energy in reserves and national parks.

The design of a gas-driven downhole pumping unit for oil production from directional and horizontal wells has been developed. The unit has no rod string, the slide and pneumatic jack are located in the tubing string. Using these units with a compressed associated gas as a working fluid will allow, unlike the hydraulic pumps, avoiding complex surface equipment for preparing the working fluid, maintenance of which is rather labour-consuming, and increasing the reliable operation of slides and downhole pumping units as a whole. In the course of experimental study of the parameters of the proposed installation it was shown on a laboratory bench showed that the fluid feed increases in direct proportion to the rate from 0.6 to 3.6 m/min. There has been obtained an empirical dependence to determine the flow of a borehole pump depending on its geometric parameters, plunger stroke length, stroke speed and gas content in the produced oil. According to the estimated parameters of the developed gas-driven unit, the supply can reach 386 m3/day, which is comparable to the supply of hydraulic units in use.

The analysis of the existing design of field apparatuses for dewaxing and crystallizing has shown their essential shortcomings which do not allow their use as field apparatuses for dewaxing oil. For elimination of these shortcomings there has been offered a design of a field apparatus for dewaxing oil using a continuous thermal hydrocyclone with the cooling and warming jacket. The characteristics of the process of asphalt resinous paraffin product receiving have been studied: temperature of melting - 54°C, crystallization temperature - 56°C, melting and crystallization heat - 189 kJ/kg, speed of sedimentation of solid particles - 1.6 · 10-3 m/s. Key parameters of the field apparatus for dewaxing oil are evaluated: height of each of 10 field apparatus for dewaxing oil bodies will make 1.0 m, diameter of the installation is 0.5 m. For conditions of V. Filanovsky field in the Northern Caspian Sea apparatus productivity on oil will make 648 t/h, on asphalt resinous paraffin product - of 19 t/h.
