    HOLE OPENER

    　　Hole Opener is usedto enlarge big surface hole in onshore and offshore oil field, that is, it is used to enlarge the hole pre-drilled by tricone bit, or it is connected above the drill bit to complete the drilling and enlarging operations at the same time. There are three type for cutter: type “SM“used for soft to medium formation; type “MH” used for medium to hard formation; type “XH” used for hard formation.

    HYDRAULIC VARIABLE GAUGE STABILIZER

    　　In directional well drilling process, Hydraulic variable gauge stabilizer uses the extended hardfacing block to reach full hole size, so as to ensure that the hydraulic variable gauge stabilizer can achieve the purpose of increasing slope and stabilizing slope when work with different drilling tool combinations in the directional well. At the same time, due to the pump is stopped, the hardfacing block will retract, and the outer diameter of hydraulic variable gauge stabilizer will become small, which is beneficial to the smooth progress of drilling and tripping, and effectively prevents the occurrence of resistance and stuck.

    SPECIAL STABILIZR WITH REAMER AND BACK REAMER

    　　Special stabilizer with reamer and back-reamer is an important tool in the drilling process to control the well deviation. It can increase the bit service life, drilling speed and well quality by effective stabilization. There are several cutting teeth special fixed on upper end and lower end of crown for reaming and back reaming. In the process of drilling and tripping, it can play the role of two-way cutting, repair the well wall, make the well trajectory to reach the ideal condition as far as possible, and prevent the phenomenon of dog legs. Especially in tripping process, it always hard to trip because of hole shrinkage etc. At this time, the back reaming teeth can play a cutting role to eliminate hole shrinkage phenomenon, thus saving time and costs for drilling.

    INTEGRAL BLADE STABILIZER

    　　Integral blade stabilizer is an important tool in the drilling process to control the well deviation. It can stabilize the drilling tools in the drilling process of oil, gas and geological exploration. It can increase the bit service life, drilling speed and well quality. There are two kinds of integral stabilizers: spiral blade stabilizer and straight blade stabilizer.
