Abstract
Degradation of hydrocarbon reserves in the fields of the Republic of Tatarstan, characterized by complicated geological conditions, high-viscosity, and paraffin oil, has made it impossible to ensure the high efficiency of traditional methods of treating the bottom-hole zone of the reservoir. The use of hydrochloric acid treatments causes a number of complications at the well, which leads to a decrease in its flow rate. The article discusses the possibility of using improved methods of selective acid treatments using soluble fibers, which make it possible to engage previously untapped productive low-permeability intervals, carried out model calculations of selective treatment on the Rockstim simulator and determined the capabilities of the compositions. Based on the results of modeling on the Rockstim simulator, the best BHT designs were obtained, analyzed and selected, including sequences of stages, volumes and rates of injection of chemical compositions, considering maximum economic profitability. Based on the results of the analysis of the work carried out, conclusions were drawn about possible directions for increasing the efficiency of acid treatment of wells.
