Apparatus and method for vibrating a casing string during cementing

摘要

A method of cementing a string of casing in a well utilizes a vibrating device downhole in the well. The vibrating device locates in the string of casing near the cement shoe. Cement slurry being pumped down the string of casing will flow through the device, out the shoe and return up the annulus. Some of the cement will flow through a bypass section of the device to power the device, causing vibrations in the casing.
