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.

This paper developed a point-contact mixed lubrication (ML) model, incorporating thermal effect, the asperity elasto-plastic deformation and the boundary film properties, to evaluate the relative severity of contact condition. Then, based on the integrity of boundary films and the sharp increase of the friction coefficient, the possibility of the occurrence of scuffing was evaluated. The model was verified with published experimental data. A systematic parametric analysis was made to investigate the influences of surface roughness, contact geometry, and the lubricant properties on contact performance. The results suggest that low surface roughness and high-quality boundary film can effectively improve the scuffing resistance under current operating conditions, while high-viscosity oil and large-radius curvature are not as much effective especially when the components work under high-sliding and high–temperature conditions.

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.

High Viscosity Oil

The limited world oil reserves force to actively develop and use fields with relatively low debit wells, as well as fields with difficult oil production conditions, with high-viscosity oil and with a significant content of foreign inclusions. One of the most unpleasant and serious complications in oil equipment is asphalt-resin-paraffin deposits. Therefore, one of the most important tasks is to study the mechanism and conditions of formation of asphalt-resin-paraffin deposits, as well as the development of effective methods to combat them. Analysis of wells in which asphalt-resin-paraffin deposits are observed, shows that the presence of paraffin, regardless of its amount in oil, poses many technological and technical tasks related to the elimination of complications associated with asphalt-resin-paraffin deposits. The presence of asphalt-resin-paraffin deposits leads to a decrease in the flow rate of wells due to clogging of pores and deterioration of filtration of oil-saturated formations. During downhole oil production, asphalt-resin-paraffins accumulate in the form of deposits on the walls of pump-compressor pipes (tubing) and oilfield equipment, thereby reducing the cross section of pipelines and lead to a decrease in the flow rate of wells. In a given hour, there are close to twenty new ways of fighting with embedded paraffin. Leather with methods of combating paraffin waxing in the process of choosing effective methods for preserving and visualizing paraffin waxes without preserving the trivial mid-repair period of robotics in the drill holes, for improving the efficiency of mathematics. The use of magnetic oil treatment devices is effective in preventing these problems. The high practical efficiency of such devices is evidenced by the increasing attention paid to the development of these devices and their patenting by various foreign firms. One such device, called a magnetic anti-paraffin device, will be discussed in detail in this paper. The device was tested at the Boryslav field from 2002 to 2007, where it gave good results in contrast to other methods. MAP has significantly reduced the percentage of asphalt-resin-paraffin deposits formation in the production area and transferred the process of their utilization to the refinery №10 in Boryslav, which in turn allows to preserve valuable components of asphalt-resin-paraffin deposits for their further use and improve the environmental condition of oil fields. The use of magnetic antiparaffin device can be effective both in the gushing of the well and in the operation of its deep-rod centrifugal and diaphragm pumps, as well as on oil pipelines. The maintenance period due to the use of magnetic antiparaffin device, in particular at OJSC Ukrnafta, increased 1.5-2.6 times. The advanced MAP device differs from other magnetic devices for liquid processing in that no power supply to the device is required for work as it works on permanent magnets.
