WAVE-INDUCING DEVICE, CASING SYSTEM AND METHOD FOR CEMENTING A CASING IN A BOREHOLE

摘要

There is described a wave-inducing device, a casing system and a method for cementing a casing in a borehole, the casing system comprising a casing that is provided with at least one wave-inducing device for providing wave motions or vibrations in cement that is between the casing and the borehole. The at least one wave-inducing device is designed to be driven by cement and/or a fluid flowing through the casing.
