摘　　要：大位移井在渤海油田边际小油田以及剩余油的有效开采中发挥着越来越重要的作用。然而随着开采时间的推移,大位移老井产量递减、出砂严重等问题突显,迫切需要对大位移老井进行深层开窗侧钻,以激发老井活力,采出剩余油并提高油田采收率。目前常规井套管开窗技术较为成熟,但大位移井深层小井眼开窗应用实例较少,因此,开展此技术研究意义重大。为此,文章通过渤海XX-J33H1井实例,就大位移深层小井眼开窗技术的实际应用进行了详细阐述。Large displacement wells play an increasingly important role in the effective exploitation of marginal small oil fields and remaining oil in Bohai Oilfield.However,with the passage of mining time,problems such as decreasing production and severe sand production in large displacement old wells have become prominent.It is urgent to carry out deep window side drilling on large displacement old wells to stimulate their vitality,extract remaining oil,and improve oilfield recovery.At present,the conventional casing window opening technology is relatively mature,but there are few application examples of deep small wellbore window opening in high displacement wells.Therefore,conducting research on this technology is of great significance.Therefore,the article elaborates in detail on the practical application of large displacement deep small wellbore window opening technology through the example of Bohai XX-J33H1 well.
