  • the drill string may extend thousands of feet, and transmitting data over this distance, below the surface, may present challenges.

  • the pressure spike or modulated sine wave is detected by a pressure sensor at or near the surface, allowing bits of data to be related through the mud.
  • the transmission rate may be relatively slow, on the order of single digit bits-per-minute.
  • the signal-to-noise ratio can be low, because the pressure spike or modulated sine wave may be attenuated once it reaches the surface.
  • the noise may high due to the proximity of machinery, such as mud pumps.
  • Electromagnetic (“e-mag”) signal transmission has also been employed.

Further, the instrument 126 may be lowered (e.g., pushed) to a predetermined depth within the drill string 104. In addition, while the instrument 126 is being lowered, the instrument line spool 122 may unspool the instrument line 120 therefrom, so as to allow the line 116 to be extended down into the drill string 104.
  • the unspooling of the instrument line 120 may be coordinated, e.g., synchronized, with the pushing by the line -pusher 265.

Further, data may be collected by the instrument 126 as transmitted to the surface via the instrument line 120. In other situations, data can be transmitted to the instrument 126 via the instrument line 120 for purposes of configuration of sensors of the instrument 126 or for relay to other equipment of the drill string 104, such as the steering components of the bottom-hole assembly (not shown).

Abstract

L'invention concerne un appareil et des procédés permettant de forer un puits de forage. L'appareil comprend un boîtier délimitant un orifice d'entrée, et un arbre couplé au boîtier et conçu pour être relié à un train de tiges de forage déployé dans le puits de forage. L'orifice d'entrée communique avec le train de tiges de forage par l'intermédiaire d'un intérieur de l'arbre, lorsque l'arbre est relié au train de tiges de forage. L'appareil comprend en outre un dispositif d'étanchéité couplé au boîtier. Le dispositif d'étanchéité a une première configuration dans laquelle le dispositif d'étanchéité est conçu pour être scellé avec une conduite d'instrument reçue à travers l'orifice d'entrée, et une seconde configuration dans laquelle le dispositif d'étanchéité est conçu pour sceller l'orifice d'entrée.
