应用稠油开发新技术提升稠油开发效果

Improving Heavy Oil Development Effect by Applying the New Heavy Oil Development Technology

开发稠油井低成本高效举升新技术已成为各油田稠油生产提质增效的一项重要研究课题。胜利油田提出了应用稠油开发新技术提升稠油开发效果,提升稠油井开发整体系统效率,实现稠油生产井低成本开发;介绍了泵下旋流降黏技术、氮气增能技术、稠油特超稠油区块配套注采一体化技术、保温技术,以及防砂注汽一体化工艺技术等5项稠油开发新技术的技术原理、使用条件和现场应用效果。实践证明,这些稠油开发新技术措施对稠油开发提质增效均十分有效。

Low-cost and high-efficiency lifting new technology to develop thick oil wells has become an important research topic for improving quality and adding benefits of heavy oil production in all kinds of oilfields.Shengli Oilfield puts forward that the heavy oil development new technology is used to enhance the effect of heavy oil development,improve overall system efficiency of heavy oil well development and achieve low-cost development of heavy oil production wells.The technology principles,using conditions and actual application effects of 5 new heavy oil development technologies used in the oilfield,namely,viscosity reduction of rotational flow under pump,increasing energy with nitrogen,integrated technology of supporting,injection and production in heavy oil and extra-heavy oil areas,insulation technology and integrated technology of sand prevention and gas injection,are introduced.Practice shows that these new heavy oil development technical measures are very effective to the quality improving and efficiency increasing of heavy oil development.
