Key Techniques for Drilling and Efficiency Improvement of Offshore Exploration Wells in the Beibu Gulf Basin

  • 摘要: 南海西部北部湾盆地海上古近系地层具有构造运动强烈、地层倾角大、夹层频繁和水敏性强等特点,钻进过程中存在井壁易失稳、井眼轨迹控制困难、导向钻进效率低和机械钻速低等问题。为解决这些问题,在区域勘探井传统钻井作业采用四开井身结构及常规钻井技术的基础上,结合区域工程地质特征,对制约钻井提效的关键因素进行了系统分析,简化了井身结构,构建了适用于南海西部北部湾盆地古近系地层的高性能强封堵钻井液,并进行了高效PDC钻头优选和钻具组合优化设计,形成了北部湾盆地海上勘探井钻井提效关键技术。该技术在北部湾盆地多口勘探井进行了应用,在井深及钻井难度相似的情况下,钻井周期与传统钻井方式相比缩短了36.1%。研究认为,北部湾盆地海上勘探井钻井提效关键技术可为北部湾盆地油气资源的高效勘探开发提供技术支持。
