Abstract

The paper analyzed the effectiveness of using catalysts of in-situ aquathermolysis together with coolant injection for the development of the Strelovskoye field. The essence of the technology lies in the injection of a special catalytic composition into the reservoir, as a result of its interaction with reservoir oil, hydrocarbons are converted, which leads to a decrease in the content of tar and asphaltenes, and, as a consequence, to a decrease in viscosity. Application of catalysts of in-situ aquathermolysis allows to increase the coverage of the formation during treatment by the heat carrier due to the reduction of molecular weight of resins and asphaltenes, which significantly reduces the viscosity of the produced oil and realizes the transformation of heavy components of oil in the formation. After viscometric tests, it was found that the dynamic viscosity of the oil after the pilot field test (PFT) at a temperature of 10 ° C decreased more than 10 times compared to the original oil. According to the results of analysis of group chemical composition, the content of asphaltenes decreased in most samples by 1.5 times compared to the original oil. There is also a decrease in the solidification temperature in all samples, the largest decrease was recorded in the sample with the date of sampling from 15.12.2022 and is 4°C. This can be explained by a decrease in the vapor content of asphaltenes. This can be explained by a decrease in the content of paraffins in the presence of a catalyst. The obtained data indicate that the initial oil in the course of thermocatalytic action undergoes significant changes due to the chemical reactions of cracking, leading to the destruction of large molecules with the formation of lighter compounds.

Key words:
