摘　　要：针对曹妃甸X油田开发中后期因注水泵、电泵耗电增加以及新调整井投产导致电量不足的生产技术问题,提出利用伴生气将部分电泵井转气举的新思路。首先从注气量和注气压力两方面讨论了气举的可行性,并综合电泵和气举生产特点,确定转气举生产的选井原则,即对比分析了气举和电泵生产的差异,根据总的气资源量,以产液量最大为目标选定转气举生产的油井。依据海上气举特点,采用半闭式气举管柱,配套推荐了气举阀及工作筒,完成了典型井气举方案设计。气举实施效果预测表明:通过打开孔板阀,当地层压力降至12.0MPa时,产液量还有316.4~484.3m3/d。该研究成果对于海上同类油井具有重要的借鉴意义。Aiming at the electricity shortage caused by the power consumption of water injection pump and electric pump in Caofeidian X oil field,it analyzes the gas injection and pressure,combines the electric pump and gas lift production to determine the selection principle of rotary gas lift production,and compares the deference between the electric pump and gas lift production.According to the characteristics of offshore gas lift,it applies the gas lift valve and working barrel to design the typical well gas lift.The application shows that liquid production is 316.4~484.3m 3/d when the pressure drops 12MPa at opening the valve.The results can be used for reference for similar offshore oil wells.
