The regularities of combustion of carbonaceous nanomaterials in two gas generating compositions with regard to the conditions of the oil wells were determined. The infuence of different amount of nanostructured soot on the regularities of combustion of pyrotechnic gas generator composition was investigated. By adding of 1.0 % nanostructured soot the lowest rate of combustion - 0.05 mm/s was reached. The content of the combustion products by the “Terra” program for composition No.2 was calculated. An optimal composition for the processing bottomhole zones of oil wells is proposed. To determine the morphology and sizes of the resulting soot particles electronic microscopic studies of the soot samples were carried out. Keywords: nanostructured soot, oil well, combustion rate, bottomhole zone of oil wells.

There are three types of the bottomhole zone treatment (BHZ): pressure, chemical reaction and heat. They are a basis of methods of increase in oil recovery [1 - 4]. Each of these types of infuence (or their combination) is implemented dur- ing the work of thermogas generators. The use of heat, chemical energy and mechanical impact on the BHZ of the combustion products is the basis of the method of a thermogas-chemical method of infuence (TCMI) [5 - 8]. Effectiveness of this method of infuence is defned not only with the quantity of an added heat, but also the fact that as a working body are used the chemically aggres- sive, heated to high temperature products of combustion, getting into the pores and cracks of productive layer, destroying and deleting from them solid hydrocarbonic deposits and emulsions. One of the most effcient, cheap and available methods of impact on BHZ is the method of TCMI by means of power saturated systems (PSS) of various nature. PSS (as without a propelling, as compris- ing metal combustible, and gunpowder) are currently in widespread use in the methods TCMI for intensifcation of oil production. A large number of thermogas-chemical sources on the basis of gunpowder, mixed fuels and py- rotechnic systems are known [9 - 14]. One of the most effcient ways to increase the oil recovery of the well is the acid treatment of a bottomhole formation zone [15]. The hydrochloric acid for processing of the layers composed of carbonaceous rocks and the so-called mud acid (acid clay) for processing of layers from terrigenous rocks are used as chemical reagents. The aim of the work is the investigation of the gas-generating composition of gas generator for pro- cessing of oil wells on the basis of ammonium nitrate, magnesium, aluminum, an epoxy resin and the nano- structured soot.
