PROTECTIVE COATINGS FOR DRILL PIPE AND ASSOCIATED METHODS
摘要
<p>A coated drill pipe (12) for use in drilling ground (16) such as in rotary drilling for explorative geophysics and associated methods and systems are disclosed and described. A protective coating can be coated over at least a portion of an exterior (28) or interior (30) surface of the drill pipe (12). The protective coating can include a polyurea such as an aromatic polyurea, a silicone modified polyurea, or an aluminized polyurea. Drill pipes can be shielded by coating a drill pipe (12) with a polyurea composition such as by spray coating. In connection with suitable systems (10) and coated or uncoated well casings, these coated drill pipes can perform for dramatically extended periods of time over conventional drill pipes.</p>
