【 摘 要 】

The work is aimed at analyzing the efficacy of a recovery enhancement technology by treatment of the bottom-hole zone of Potochnoye field. Such technologies become a must, if there is a possibility of dissolution of rocks or elements that sediment and reduce permeability. When developing a bottom-hole zone, the choice of reagents taking into account all reservoir conditions and the properties of its fluid should be scientifically justified. The results presented in this work are used when planning and implementing technologies for enhanced recovery by treating the field bottom-hole zone. The research analyzes laboratory experiments mimicking the conditions of Potochnoye field. We have studied the core samples of Uryevsk (zones YuV1, AB13 and Ach2) and Severo-Potochnoye (zone BV6) fields and their reaction to chemicals. Compound Eltinoks/1.2 was found to have low corrosion activity in reservoir conditions, correspond to requirements to iron content and stabilization, be compatible with water and completely suitable for operating conditions of Potochnoye field. In addition, the work considers the efficacy of the technologies and compounds for separate zones, which were used to make recommended compounds accounting for the compatibility of reagents with reservoir water, core solubility and compatibility with oil.
