THEORETICAL JUSTIFICATION OF THE THERMAL METHOD – STEAM CYCLIC TREATMENT OF WELLS OF THE X DEPOSIT

Abstract

Enhanced oil recovery from active fields is equivalent to the discovery of new fields, making this issue critical to all oil-producing countries around the world. Of course, among all modern methods of increasing oil recovery from reservoirs, thermal methods are the most technically and technologically prepared. They make it possible to extract oil with a viscosity of up to 100 MPa and at the same time increase the final oil recovery by 30-50%. In particular, the thermal steam method is widely used both in fields in the CIS countries and abroad. The main factors that determine the growth of oil production using thermal methods include: Availability of significant resources of high-viscosity oil. Application of highly effective technologies for influencing oil deposits. Availability of necessary heat and power equipment. Use of heat-resistant equipment for wells and on the surface. Effective control and regulation of processes inside wells. The widespread development of methods for thermal oil production is associated with the solution of a complex set of scientific and technical problems. Among these tasks, special attention is paid to: The study of oil recovery mechanisms in various geological and physical conditions. The determination of opportunities for effective use of the features of the geological structure of specific fields. The development of combined methods for increasing oil recovery, including thermal methods and others, in order to improve technological processes and achieve high oil recovery rates at the level of 50-60%. The aim of this article is to analyze and justify the choice of a specific thermal oil production technology, namely the method of steam-cyclic well treatment, which is especially relevant for the production of high-viscosity oils.
