The integral blade stabilizer type WL can be divided into two types: the drilling string type and the near bit type. This tool is used to prevent the well from tilting in drilling operation. It can prolong the service life of the bit;effectively reduce down hole vibration and MWD failures and also promote penetration rate and wellbore quality.
