Tuyau de forage Poids lourd (HWDP)

Tuyau de forage Poids lourd (HWDP) Notre poids lourd tuyau de forage (HWDP) offre une transition progressive de lourdes, rigid drill collars to the more flexible drill pipe which helps to reduce the number of fatigue failures seen directly above the Bottom Hole Assembly (BHA). Nous offrons du poids lourd en 3.1 / 2 ", 4", 5″ and 5.1/2″ consisting of hard banded tool joints and raised wear pads on central upsets to optimize wear resistance. Nous offrons deux types de configurations HWDP; Standard HWDP et Spiral HWDP. Standard HWDP Prevents stress concentration and allows directional drilling with controlled torque and reduces differential pressure sticking. Spiral HWDP Designed to handle maximum stresses induced at harsh drilling environments in vertical and directional wells. Partage plusieurs des mêmes caractéristiques de la HWDP standard. Better reduction in differential sticking Increased weight and stiffness Minimizes wear Improves cutting circulation for better hole cleaning Our preferred applications of hard banding for drill pipe tool joints and BHA components (HWDP, Colliers Drill) are ARNCO 350XT or Duraband NC, NS-1 à la fois certifié; qui ne sont pas seulement à protéger le tube de forage de porter, mais aussi pour protéger le boîtier. We use a robotic welding system for hardbanding drill pipe.
