渤海浅部疏松地层旋转导向轨迹控制关键技术
|
摘要
旋转导向工具在渤海油田应用较为广泛,但长期以来由于旋转导向工具在渤海浅部地层的造斜率不稳定,不能完全满足轨迹控制要求,因此一般是上部采用螺杆马达钻具,中途起钻更换旋转导向钻具。但螺杆马达钻具一方面滑动定向时效较低,另一方面起钻更换为旋转导向钻具需耗时12~15 h。若能直接采用旋转导向工具,取消中间的起钻换钻具步骤,作业效率将大幅度提高。通过定向井轨迹优化、旋转导向工具对比优选、钻井液性能优化等技术措施,成功地在渤海浅部疏松地层实现了旋转导向控制轨迹技术,大幅提高了作业效率。
Rotary steering tools are widely used in Bohai oilfield. Because of the instable built-up rate,screw motor drilling tools are generally adopted at the shallow formation drilling,and then rotary steering drilling tools are used instead. When with the screw motor drilling tools,slide steering efficiency is low; on the other hand,it will take 12 ~ 15 h to trip out for the drilling tools replacement. If the rotary steering drilling tools are used from the very beginning without tripping out for drilling tools replacement,the operation efficiency will be greatly improved. By the technical measures of directional well trajectory optimization,selecting rotary steering tools by comparison and drilling fluid performance optimization,rotary steering drilling technology has been successfully applied in the shallow unconsolidated formation of Bohai.
