IMPROVEMENT OF APPROACHES FOR IDENTIFYING COMPLICATING FACTORS OF ARPD AND W/O EMULSIONS IN OIL GATHERING SYSTEMS
Annotation. Specialists from JSC "Izhevsk Oil Scientific Center" conducted studies aimed at identifying complicating factors in pipeline system facilities. Laboratory and field investigations were carried out regarding the studied issue: measuring viscosity of pumped medium under laboratory conditions, measuring viscosity of pumped medium under field conditions, inspection of internal pipeline surface, flushing operations, measuring temperature of pumped liquid, and pipeline monitoring without the use of a demulsifier. These activities were accompanied by hydraulic calculations. In 29% of cases, the complicated pipeline stock of PJSC "Udmurtnеft" named after V.I. Kudinov is simultaneously affected by both ARPD (asphalt-resin-paraffin deposits) and W/O emulsions (water-in-oil emulsions). According to statistical analysis, the pipeline system of the Sharkan oil field is the most affected by ARPD (30%) and W/O emulsions (35%), compared to other fields of PJSC "Udmurtnеft" named after V.I. Kudinov. For the conditions of PJSC "Udmurtnеft" named after V.I. Kudinov and companies with similar transportation conditions of oil-containing liquids, a more advanced approach is required when classifying pipelines as part of the "complicated stock" due to ARPD/W/O emulsion issues. As a result of the comprehensive measures undertaken, the problem of accurate identification of complicating factors has been confirmed. An improved approach to determining complicating factors in field pipelines revealed discrepancies between previously identified complications and those identified using the updated methodology currently applied by PJSC "Udmurtnеft" named after V.I. Kudinov.
Keywords: asphalt-resin-paraffin deposits (ARPD), water-in-oil emulsion, protection technologies, cleaning device, demulsifier, viscosity, hydraulic calculations, field pipeline, pressure, complicated stock.
