ANALYSIS AND JUSTIFICATION OF MEASURES TO PREVENT OPERATIONAL COMPLICATIONS AT THE WELLS OF THE AKKAR FIELD

Abstract

The article discusses the features of the formation of asphaltene-tar-paraffin deposits (AFS) during the extraction of heavy, highly paraffinic oils using the example of the Severny Akkar deposit in the Mangistau region of the Republic of Kazakhstan. It is shown that high levels of paraffins, resins, and asphaltenes combined with thermodynamic conditions of well operation lead to intensive formation of organic deposits in the reservoir, bottom-hole zone, and tubing, significantly complicating the oil production process. The effectiveness of thermal and acidic methods of influencing wells exposed to AFS is analyzed. It has been established that heat treatments can stabilize the operation of wells and increase the intertreatment period, but they are temporary. The expediency of using preventive methods, including the use of paraffin deposition inhibitors and combined chemical and thermal technologies, is substantiated.
