Drilling stabilizer is an important tool to control hole deviation in petroleum and gas exploration drilling process. The types can be divided into drill string type and near bit type. When equipped high rigidity drill collar and bigger drill pressure, stabilizer can minimize hole deviation and avoid "dogleg" severity if being used properly.The stabilizer improve the quality of well and speed of drilling,which decrease the cost of drilling.

Construction
