Specialists at Samotlorneftegaz, one of Rosneft's key production assets, have developed a system to protect electric centrifugal pumps from mechanical impurities. The new technology can significantly increase the reliability and efficiency of the equipment. As a result of installing innovative filters in the design, the equipment's failure rate has increased by 2.3 times to 206 days. The economic effect of the innovation in the next five years may amount to about 850 million rubles.
Mechanical impurities contained in formation fluid are one of the main reasons for the failure of electric centrifugal pumps. Small-sized pumps, due to the specific design, especially need protection from sand and proppant. After successful pilot tests at the Samotlor field, two of the most effective Russian-made filters were identified. The gravity-slot filter combines two cleaning methods at once – mechanical filtration and separation of impurities using centrifugal forces. The efficiency of the volume-wire filter is ensured by the unique properties of the filter material. The equipment allows for the screening of mechanical impurities up to 100 micrometers in size and has a throughput capacity of up to 200 cubic meters of liquid per day.
The use of filters to improve the reliability of small-sized pumps has great potential. The production fund of Samotlorneftegaz includes more than 300 non-standard diameter wells with significant removal of mechanical impurities.
Development of technological potential is one of the key elements of Rosneft's strategy. The company prioritizes innovation activities, defining technological leadership as a key factor in competitiveness in the oil market.
