Drilling stabilizer is an important tool to control hole deviation in petroleum and gas exploration drilling process. The types of it can be divided into drill string type and near bit type. At present, we developed HF3000 and HF5000 type stabilizer, which are widely used in international drilling operation.
Integral straight blade stabilizer,Integral 3-straight rib stabilizer,integral 4-straight rib
stabilizer,and Integral multi-straight rib stabilizer ,which working surface are provided with
carbide insert compound and overlay,etc. The body is made from high strength alloy steel
of heat treated.
