【摘要】：由于水平井井深、水平段长、井眼条件差、通井管柱设计不合理等原因,通井管柱与完井管柱匹配度低、通井时效过长、通井管柱下入困难,增加了井控风险和作业成本。针对通井困难这一突出问题,通过理论分析,综合考虑井眼情况和完井管柱配置,分析了通井扶正器、通井管柱底部扶正器组合(BHA)和送入管柱对完井管柱安全入井的影响,提出了综合考虑井眼情况和完井管柱配置的个性化通井优化方案,即加长单扶通井,双扶通井BHA优化和增加送入管柱加重钻杆数等优化措施,为超深超长裸眼水平井完井管柱的顺利入井提供了技术支撑。
[Abstract]:Because of the deep, long horizontal section, poor wellbore condition and unreasonable design of the through string, the matching degree between the through string and the completion string is low, the through well aging is too long, and it is difficult to enter the through string, which increases the risk of well control and the operating cost. In view of the difficulty of passing through well, through theoretical analysis, considering the well hole condition and completion string configuration, the influence of through well centralizer, bottom centralizer of through well string (BHA) and feed string on the safe entry of completion string is analyzed. In this paper, the optimization scheme of individualized through well with comprehensive consideration of borehole condition and completion string configuration is put forward, that is, the optimization measures such as lengthening single through well, double through well BHA optimization and increasing the number of heavy drilling pipes for feed string are put forward. It provides technical support for the smooth entry of the completion string of ultra deep and long open hole horizontal well.
