Калибраторы-расширители типа КРп-2СТ и спиральные эксцентричные

The use of these reamer-bits allows increasing average BHA pull-out-of-hole after drilling and thus reduce pulling out time.

Reamer bits KRp-2CT

Reamer bits are designed for calibrating and reaming well sections represented by medium, hard and abrasive formations. Reamer bits allow reaming horizontal and high dogleg severity wells preventing accidental sidetracking and sizing wellbore to nominal diameter both moving down and up.

Reamer bits are produced with two tapered surfaces. Tapered surfaces, reinforced with tungsten carbide inserts with cutting edge, comprise reaming part of a tool.

Spiral eccentric reamer-bits

Designed for calibrating and reaming well sections represented by soft and medium rocks, as well as for eliminating the micro tortuosity.

The eccentric shape of the blades of the KRpC-L with PDC cutting structure makes it possible to use the reamer with bits equal to or larger than the nominal diameter of the reamer.
