摘要

While reamers have been in use for more than a century, reliability issues have kept them out of the spotlight... until now. Hole openers are not new to the industry. In the early days of rotary drilling, bits lost gauge as they traveled down hole. To allow for the setting of casing, this tapered effect had to be dealt with. In its origin, a reamer, or a hole opener as they were referred to then, was run to ensure adequate hole size throughout the well bore. As early as the 1930s, stationary reamers were used to open up pilot holes drilled for sidetracks and whipstocks.
