摘　　要：阿尔及利亚扎尔则油田开采以气举方式为主,由于无单井固定配气装置,任何节点参数的改变都可能对整个系统运行的稳定造成影响。由于地面系统稳定性差,且开发后期单井井筒问题频发,有限生产管理资源难以满足高效管理油田的需求。通过深入分析系统及单井中影响气举效率的技术因素和管理因素,提出了优化单井配气和气举工艺参数的方法和思路,同时寻求建立地面系统压力稳定监测报警系统,以实现系统优化和稳定运行;提出解决井筒问题的技术性预防措施,配以按单井产量分级管理方法,优化管理资源。实施后高产井单井月检查覆盖率可以达到95%以上,达到在最少投资情况下最大限度地提高油田开发管理水平的目的。Gas lift is the main artificial lift technique in Zarzaitine oilfield in Algeria.For there is no fixed ration supplying gas equipment for each single well in wellhead,it is possible that parameters change in any key point will affect the stable running of whole system.Because of the poor stability of ground facilities and frequent occurring of wellbore problems at late stage of development,limited management resources can not satisfy the requirement of high efficiency of oilfield development.Based on the deep analysis of the system and technological factors and managerial factors influencing gas lift efficiency for single well,the method way to optimize ration supplying gas for single well and gas lift technical parameters were given in this paper.Besides,the pressure monitoring and alarming equipment for ground system was explored to make sure the system optimization and running stability.The technical prevent measures has been proposed to solve the well bore problems,which was combined with grading administration in single well to optimize managerial resource.The monthly inspection covering rate for single high production well can reach more than 95% after implement,and achieve the purpose of enhancing the development and management level in maximum with the minimum cost.
