多年来使用控时钻井技术、水泥塞或永久性斜向器在裸眼中侧钻。然而 ,在应用中发现了一些问题 ,提出了可供选择的侧钻方式或技术。例如 ,在控时钻进技术中 ,硬地层中很难形成侧向井眼 ,而软地层中可能形成虚井眼。上述两种情况都很费时 ,而且费用高。为了解决这个问题 ,研制并测试了裸眼可回收式侧钻系统。设计中考虑的因素包括裸眼中的锚定和回收 ,同时在整个钻井过程中保持完整性。本文详细叙述了设计过程中的重复论证 Over the years the use of controlled drilling technology, cement plug or permanent oblique side hole in the naked eye. However, some problems have been found in the application and alternative sidetracking methods or technologies have been proposed. For example, in controlled-time drilling, lateral wellbores are hard to form in hard formations and virtual wells may form in soft formations. Both of these situations are time consuming and costly. In order to solve this problem, the naked eye recuperative sidetrack drilling system was developed and tested. Factors considered in the design include anchoring and recovery in the open eye while maintaining integrity throughout the drilling process.
