The physical methods of enhanced oil recovery using electromagnetic fields are studied in this paper. Purpose of the work is to study the dependence of the main quantities that determine the volume of filtered oil, including the viscosity of oil, on the parameters (temperature, intensity and frequency) of thermal and electromagnetic fields, and optimize these parameters for maximum oil recovery factor using electric fields and steam treatment of the formation.It is proposed to combine the most effective and environmentally friendly methods to increase oil production. In the developed technique, methods of converting steam energy are used to create a torque of the drilling device with simultaneous steam treatment of the bottomhole zone of the reservoir. As well as the impact of an alternating electromagnetic field on the reservoir matrix and interstratal liquid fluids to create currents, increase the mobility of molecules of liquid fluids, and, as a consequence, increase the temperature and lower the viscosity of oil, which will increase oil recovery. As a result of numerous experimental experiments carried out using the original setup in the laboratory of the branch of the Tyumen Industrial University in Nizhnevartovsk, it was shown that a decrease in viscosity is observed only when exposed to simultaneous thermal and electromagnetic fields.
The paper examines the results of theoretical and experimental studies of different interaction of ionizing emission photons with substances, in particular, the photo effect and the Compton scattering of these photons. The paper substantiates a new method of determining the recoil electrons number - the photoelectrons number ratio. The results of certain measurements are presented. The analysis of the results showed that there are noticeable divergences between the theoretical calculations and the experimental data.
The work shows various ways to improve the efficiency of oil production. A comparative analysis was carried out. Considered the most environmentally friendly ways. Considered physical models and the most important averaged parameters for them are defined. Identified ways to influence these parameters. The expressions are shown that allow to calculate the volumes of oil filtered through the sections of the bottomhole zone of the reservoir. The problem of determining the viscosity of oil. The methods of steam-thermal impact on the formation, their advantages and opportunities are considered in detail. Identified problems, shows how to solve them. Solutions were found for turning water into saturated steam in a closed volume of a drilling tool. The quantities that evaluate the effectiveness of the device are determined and calculated quantitatively. The optimal size and shape of the nozzles are determined. Calculated steam flow rate from the nozzles of the device, the reactive forces arising in the device and the torque generated by the forces. The relevance and prospects of these methods are shown. at development of deposits with high viscosity oils.
