Ten years of great development in chemical technology, praising China's prosperity and strength in the prosperous age, and making the world more lively and exciting with everyone's participation. [Ten Years of Great Development of Chemical Equipment] Continuously update the summary post, welcome to participate in the discussion https://bbs.hcbbs.com/thread-3576046-1-1.html Everyone is welcome to participate in the forum series for exchanges and discussions to enhance quality awareness and promote high-quality development-------------------------------------------------- On August 21, 2023, the pilot test of the country's first spiral vane pump, the spiral vane multiphase mixed pump, was conducted in the Fengcheng Oilfield operation area of Xinjiang Oilfield Company for more than 4 months, and multiple indicators met the design requirements. According to reports, the transportation problem of high-temperature multi-phase media in closed gathering and transportation in Fengcheng Oilfield is a global problem. Currently, screw pumps have to be frequently replaced and repaired to support the closed gathering and transportation work. Problems such as short service life, difficult maintenance, and high cost of screw pumps seriously affect production and operations. The first domestic spiral vane pump adopts the ternary theory design concept and has the functions of a compressor. It has the advantages of high temperature resistance, wear resistance, corrosion resistance, compact structure, easy maintenance, low operating cost, and energy saving. The spiral vane pump can reduce the frequency of failure of the closed system oil pump, extend its service life, reduce manual labor intensity, avoid environmental pollution, and effectively ensure the safe and smooth operation of the closed gathering and transportation system. In addition, in order to ensure the reliability of seal flushing and cooling water supply of the spiral blade multi-phase mixed pump, the Fengcheng Oilfield operating area installed a circulating water supply system, equipped with relevant automated monitoring equipment and alarm chain control system.
The "spiral blade multiphase mixed transport pump" developed by the team of Professor Shi Guangtai of the School of Energy and Power Engineering of Xihua University underwent on-site application trial operation in the Fengcheng Oilfield operating area of PetroChina Xinjiang Oilfield Company. The test was officially launched on April 12 this year. Since the operation, all indicators have shown normality. On August 18, the Capital Construction Engineering Office of PetroChina Xinjiang Oilfield Company organized an acceptance meeting for the spiral vane pump operation test results. The meeting listened to reports on the test work of the Fengcheng Oilfield Operation Area and Xihua University. The participating experts conducted questions and discussions on the test results, innovation and advancement. The expert group unanimously believed that the test pump's flow rate, lift, shaft power and efficiency met the design requirements, effectively solving the "stuck neck" problem in the closed gathering and transportation process of Fengcheng Oilfield. ； The spiral blade multi-phase mixed transport pump is the first in China. It is very innovative and advanced and has broad application prospects. ； It is recommended to expand the scope of the test to provide experience for the adjustment and transformation of old oil fields and the construction of production capacity in new areas. The transportation problem of high-temperature multiphase medium in closed gathering and transportation in Fengcheng Oilfield is a domestic and global problem, which seriously affects the production and operation of Fengcheng Oilfield. The spiral blade multiphase mixed transportation pump has the function of large displacement, stable pressure, and adaptability to multiphase mixed transportation of gas, liquid, and solid. ； It has the characteristics of high gas content (gas content 10-85%) mixed transport, overcoming slug flow and strong resistance to dry running. ； It has the advantages of high temperature resistance, wear resistance, corrosion resistance, compact structure, convenient maintenance, low operating cost, and energy saving. Compared with screw pumps with the same flow rate and lift, the service life can be extended by more than 6 months, the motor configuration power can be reduced by 20kW/unit, and the annual electricity saving is about 140,000 kWh/unit.
