ABSTRACT

Thermal methods, in particular steam treatment, are the most needed among the tertiary methods of increasing the extraction of Heavy crude oil. The use of catalysts in couple with the steam injection is promising method. This article is about experimenting with the modelling of steam effects on the oil-saturated sandstone, using a dimensional-based catalyst based on iron. The composition and physico-chemical characteristics of the products of the thermocatalytic effects have been studied. It has been shown that the use of a catalyst, combined with a hydrogen donor, can significantly reduce the share of tar and asphaltenes. The share of saturated hydrocarbons is increasing. This reduces the viscosity of the oil. It is also established that the destructive hydrogenation reduces the degree of sulfurization, which is important for Heavy high-sulfur crude oil of the Volga-Ural Basin.
