The roller reamer is designed for various reaming operation but particularly for stabilization purposes when drilling in very abrasive formations. It will fit hole sizes ranging from 6"28". In addition, each body by simple adjustment of blocks and proper selection of cutters, will suit a wide range of hole sizes.

The body of fixed diameter hole opener is made of tough heat treated alloy steel for maximum strength. Cutter arms, equipped with removable cutter, are hard-faced and welded on body. The hole openers have three or six jet tubes with replaceable nozzles, so that jet streams quickly clean the enlarged hole. Our company have the following 2 kinds of fixed diameter hole opener: 3 roller cones hole opener and 4 roller cones hole opener.

The hydraulic expandable under reamer is designed to enlarge the wellbore in a large range of drilling operations. It enlarges the wellbore for improved ecd control, casing running and cementing clearance. The hydraulic expandable under reamer is ideal for use with rotary steerable drilling systems, providing wellbore quality unachievable with other reaming tools. Superior wellbore quality coupled with a proven history of performance makes the hydraulic expandable under reamer the preferred choice for reaming operations. featuresreliable hydraulic actuation to ensure a full-gauge concentric wellboredependable cutter block retraction to avoid stuck bhasaggressive pdc cutter blocks for higher rop in a wide range of formation typesintegral backreaming capability to ensure a full-diameter bore is constructedintegrated jet nozzle and flow paths to improve clean-out while drilling the hydraulic expandable under reamer is particularly well suited to the most challenging applications.
