The article addresses viscous and high-viscosity oil production methods that are also relevant to Tazovskoye oil-gas condensate field. Heat-affected zones have been identified to assure the most effective development of the viscous and high-viscosity oil field. Study and patent research results have been used to determine four most effective thermal methods of high-viscosity oil rheological properties con-trol: local heating, co-current heating, local stage heating, and local co-current heating. Existing thermal systems for the implementation of these thermal methods have been analyzed and electrothermal systems based on induction technology have been chosen. The efficiency of induction technology is due to a high range of the thermal flow formed and implementation of two modes: temperature maintenance and emergency heating. Local heating may be ensured by an induction downhole heater of the face area or an induction electric steam generator for the thermal action not only on the face area, but the entire producing formation. A heating device has been proposed based on results of the patent research of induction heating systems for high-viscosity oil. A versatile magnet-operated component has been proposed as a heating body of the induction heating system.

The results of a pilot application of a chemical composition for enhanced oil recovery developed at the IPC SB RAS are presented. The EOR-composition was tested in 2014 at the Permian-Carboniferous heavy oil deposit at the Usinskoye oil field. It is very effective for an increase in oil production rate and decrease in water cuttings of well production. In terms of the additionally produced oil, the resulting effect is up to 800 tons per well and its duration is up to 6 months. The application of technologies of low-productivity-well stimulation using the oil-displacing IKhNPRO system with controlled viscosity and alkalinity is thought to be promising. This composition is proposed for the cold’ stimulation of high-viscosity oil production as an alternative to thermal methods.

High Viscosity Oil

The need for high-viscosity oil production in the fields of the Russian Federation is substantiated. The technology of high-viscosity oil production by the thermoshaft method is considered, harmful and hazardous factors at the workplaces of the underground group workers are identified, first of all, the microclimate parameters (increased air temperature of the working area), which effect on the formation of occupational diseases and an increase in the risk of injury to the personnel. The main problems associated with the imperfection of the technology of the thermoshaft method for the extraction of high-viscosity oil, which effect on the safety of conducting operations for the extraction of heavy oil, are investigated, and presented. The options of opening up a high-viscosity oil field with a modular mine, which allows to normalize the thermal regime in mine workings, improve working conditions of the oil miners, reduce the level of occupational diseases and injury rate, reduce the volume of work and the costs of mining operations and maintenance of the mine workings, are considered. The system for the development of the Yaregskoye field of high-viscosity oil with the division of the mine field into separate production blocks using a sectional ventilation scheme, which provides for independent ventilation of each module due to the construction of an air supply and air exhaust shafts in each block-module of the mine is proposed in the article. The surface and underground complex of shafts for the construction of a modular mine is presented. The calculation is carried out and the results of technical solutions for airing various modifications of mini — mines are given. The drilling gallery was designed, which is typical for all the options of opening. In the designed modular mines, a closed oil gathering system is proposed. Comparative economic analysis showed the efficiency of the development of new areas of the Yaregskoye high-viscosity oil field using the construction of modular mines.

High Viscosity Oil

High-viscosity oil recovery often requires thermal methods of enhanced oil recovery combining surface acting agent (SAA) injection. Thermal treatment allows increasing hydrocarbon movability. Efficiency raisings’ limiting factor of this method includes injecting agent’s thermal loss (water and steam) as well as SAA molecules thermal destruction. This article assesses nanoparticles adding in SAA water solution’s influence. The authors consider a theoretic capability of increasing heat exchange’s inetnsity between oil reservoir and injected agents by means of adding nanoparticles as well as increase of the SAA thermostability’s capability under high temperatures influence. The results of the laboratory experiments on SAA’s adsorbed layer structure on the surface of solid state show the structure’s dependence on SAA concentration in the solution. According to the developed mathematic model, a periodic adsorbed field will lead to the increase of heat transfer coefficient by means of the Nusselt number increment. This will allow increasing efficiency of thermal methods EOR application.

While choosing an optimal field development strategy it is necessary to take into account the possible effects of oil structural-mechanical qualities. The presented methods allow estimating the effect of structural-mechanical qualities of the production of oil with high levels of asphaltene and tarry substances. After completing all calculations and designing, a parameter set is created for optimal depletion mechanisms of the production of nonlinear high-viscosity non-Newtonian oil.
