●滚轮稳定器：(WG型)用于各种铰孔及稳定工作,在研磨地层做稳定器用。根据不同的地层硬度，可分别选用铣齿滚轮、平齿点滚轮和镶齿滚轮。这是一种***工具。他用于5 7/8″到26″的井眼。此外，同是一个主体，适当配置滚轮总成就可以用于不同大小的井眼。
Roller Reamer
The Roller reamer is designed for any reaming operation and particularly for stabilization purposes when drilling in abrasive formati***. According to the different hardnesses of formati***,you may separately select sharp-fanged roller,wide-fanged roller or tungsten carbide compacts roller. In addition, each body, by simple adjustment of blocks and proper selection of cutters, will suit a wide range of hole sizes.
Its body is made of alloy steel, fully heat treated to 285-341 Brinell hardness and 54J minimum impact strength.
Pressure balanced sealed journal bearing assembly has a long service life.
Three different types (T, F and B) of rollers are offered.
Type T: Milled, machined with hard-faced sharp teeth for soft formati***
Type F: Milled, machined with hard-faced flat teeth, for medium hard formati***
Type B: Equipped with pressed-in tungsten carbide butt***, for hard formati***
