Abstract

One of the main tasks of oil producing industry is the increase of producible oil index and the oil-field development rate. In the context of hydrocarbon crude stock reduction and the increasing energy consumption, the issue of hard to recover reserves development occurs and the high-viscosity heavy oil rates are considered to be such reserves. Chemical agents (resolvents) addition, mechanical effects, magnetic and electrostatic fields imposing, and thermal treatment are the basic methods of oil viscosity reduction. The main method of heating and viscosity reduction of hard to recover oil rates is the application of gas producers, which operate using solid fuel. The use of ballistite fuels in gas producers with the possibility of adding various coolants of different concentrations allows regulating temperature and emission characteristics of homogeneous combustion products to the level specified by the recovery methods. The paper presents the methods and the results of heat emission calculation of the combustion products of a gas producer that operates using solid fuel. Water is used as a coolant. The combustion products are represented by the aggregation of monodisperse system of sootflakes and gas phase. Using the method of computing experiment, the authors studied the influence of a coolant concentration (0 %, 10 % and 25 %) on the temperature and spectral and integral emission parameters (fluence rate and emissivity factor) of combustion products at different pressures (0,1 MPa and 7 MPa). It was established that the cooling agents addition influences on the fluence rate value more than the emissivity factor when the combustion products have only gas phase. The growth of soot content causes the increase of spectral and integral emission parameters even when adding agents lowering combustion products temperature. The authors present the characteristic curve of integral parameters on the emitting layer thickness.
