A: Selection depends on the formation. HF1000 is ideal for standard abrasive formations, while HF3000 (TCI) is recommended for extremely hard and abrasive rock. We also offer specialized coatings for soft formations to maximize service life.
A: A Near-Bit Stabilizer is placed directly above the drill bit to provide maximum rigidity and control for vertical or directional drilling. A String Stabilizer is placed further up the BHA to support the drill string and prevent buckling.
A: Yes. All Shangshan Petro stabilizers are manufactured with API Spec 7-1 connections. We also provide stress relief features (SRG) and cold-rolled threads to enhance connection life under high-torque conditions.
A: Absolutely. For directional drilling requiring MWD or LWD tools, we provide Non-Magnetic Stabilizers manufactured from high-purity non-magnetic alloys to prevent interference with surveying instruments.
