摘　　要：文章提出一种适用于大液量水平井、可进行无极调控分段液量的智能分采技术,有效解决了以往南海东部大液量水平井沿程均衡动用的难题。通过对X油田A13井开展地质油藏与井筒工艺一体化设计,制定水平段分采方案,在满足目标油藏经济有效开发最大液量2 600 m^(3)/d的前提下,成功解决了该井水平段因沿程地质模式差异而导致的平面矛盾突出问题。该井投产后,通过关闭跟端分段,测试含水下降7.3%,日产油平均增加44 m^(3)/d,降水增油效果显著。应用实践表明,该技术适用于南海东部大液量水平井的智能分采,为类似油田高效增产挖潜提供了全新方案。This paper presents an intelligent production technology which is suitable for horizontal Wells with large fluid volume and can control the fluid volume in a segmented way without poles,effectively overcoming the diff icult problem of balanced operation along a horizontal well with large fluid volume in the east of the South China Sea.Through the integrated design of geological reservoir and wellbore technology for well A13 of X oilf ield,the production plan of horizontal section was formulated.Under the premise of meeting the maximum fluid volume of 2 600 m~3/d for economic and effective development of the target reservoir,the prominent plane contradiction caused by the difference of geological modes in the horizontal section of this well was successfully solved.After the well was put into operation,the test results showed that the water cut decreased by 7.3%,and the average daily oil production increased by 44 m~3/d.The application practice shows that the technology is suitable for intelligent production of horizontal Wells with large fluid volume in the eastern part of the South China Sea,and provides a new scheme for eff icient production increase and potential exploitation of similar oil f ields.
