摘要: A method to be used when performing drilling in a well bore and device for the are disclosed. The includes positioning drill string comprising at least two pipe conduits, an upper end, lower end tool, thereby forming outer annulus between wall string. section one u-shaped is drilled. first fluid with density fed into above section, second provided within around where larger than density.
