ANALYSIS OF THE OPERATION OF THE SYSTEMS FOR THE COLLECTION AND PREPARATION OF WELLS FROM THE BITTEMSKOYE FIELD
The article considers the system of oil collection and treatment at the Bittemskoye field. The performed hydraulic calculation of the pipeline showed that the laminar flow of the gas-liquid mixture takes place in the sections k.3 - t.55, k.40 - t.22а and k.39 - t.60 of the pipeline route. The operational experience of such systems, assembled from pipes with an overestimated diameter, showed that a considerable part of them is subject to specific destruction along the lower generatrix of pipes at a rate of 3 or more mm/year (riveted corrosion). Destruction is represented as a one- or two-row groove. To eliminate this type of corrosion, it is proposed to install pipes with a smaller diameter at sections k.40 - t.22a and k.39 - t.60.
