摘要
窄窗口钻井问题广泛存在于我国西部油田和深水、深部复杂地层,已成为影响和制约石油勘探开发进程与钻井施工的技术瓶颈。从安全密度窗口的定义出发,系统总结了窄窗口钻井的几种特殊情况,从窄窗口钻井的地层特点、工程施工难点、以及现有技术的缺陷等方面,提出了解决窄窗口钻井问题的主要技术对策,并给出了部分应用实例分析,为国内解决窄密度窗口钻井技术难点提供了有效的对策分析方法和技术参考。
Difficulties of narrow window drilling existing in China＇s western oil fields and deepwater ＆ deep formation,had an impact and constraints of oil exploration ＆ development and drilling operation. From the definition of secure drilling, The author summarized systematically several special conditions of narrow window drilling. And then the main technical solutions were obtained from the narrow window drilling of formation features, engineering construction difficulties and shortcomings of existing application technology, and some examples of technical applications were also given,providing a practical reference for solving the problem of narrow window drilling technology.
