Reaming part of stabilizer - tapered surfaces reinforced with tungsten carbide inserts with cutting edge

Reamer Stabilizers

Reamer stabilizer KRp-2St is designed for calibrating and reaming well sections represented by medium, hard and abrasive formations. Reamer stabilizers allow reaming horizontal and high dogleg severity wells preventing accidental sidetracking and sizing wellbore to nominal diameter.

Reamer stabilizers are produced with two tapered surfaces. Tapered surfaces, reinforced with tungsten carbide inserts with cutting edge, comprise reaming part of a tool. Letter «p» on nomenclature designates «box-pin» type body, letter «S» spiral blades, «L» left-hand thread (designated with an «LH» at the end of the thread designation), number at the end of code quantity of blades.
