河南油田稠油出砂冷采几个重要问题探讨

Several Important Issues on Cold Production of Heavy Oil in Henan Oilfield

  • 摘要: 在根据现场资料分析研究的基础上,结合河南油田稠油油藏特点,对影响稠油出砂冷来技术发展的4个主要问题进行了探讨。结果表明:稠油出砂冷采井必须采用大孔径、深穿透、高密度射孔技术;采用适应高含砂量和高原油粘度的高转速螺杆泵,且螺杆泵下入油层底部;特、超稠油是出砂冷采技术的主要应用领域,现场试验必须有足够的时间,并采取相应的技术措施;对受断层控制的窄条状多层稠油油藏,宜采用丛式定向井进行开发。

     

    Abstract: Four main problems that have effects on heavy oil cold production technique are discussed on base of field data. Big-hole, deep penetration and high density pattern perforation technology must be applied in cold production wells; progressive cavity pumps with high rotation speed and being suitable for high sand cut and large crude densi ty should be used and run to the bottom of oil layers; ultraheavy and superheavy oil layers are the main targets for cold production; and directional cluster wells are suitable for development of multiplayer narrow string heavy oil reservoirs controlled by faults.
