Integral spiral blade stabilizer
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
Integral Spiral Blade Stabilizer is divided into Integral 3-Spiral Blade Stabilizer, Integral 4-Spiral Blade Stabilizer .There are four kinds of abrasive resistant materials on the working surface of stabilizer: insert tungsten carbide buttons, insert diamond compound body, low temperature welding tungsten carbide pieces, hardfacing electrode on the surface etc.
