Replaceable Sleeve Stabilizer
Replaceable sleeve stabilizer consists of mandrel and sleeve. The function is the same as spiral integral blade stabilizer. It can suit to different hole sizes and increase working life by changing the different size sleeve. The sleeve is threaded on the mandrel, so the sleeve can be fasten to the mandrel tightly and changed easily.

Special Stabilizer with Reamer and Back-reamer
Special stabilizer with reamer and back-reamer is an important tool in the drilling engineering to prevent well deviation. Apply to stabilize drilling tools in the drilling process of oil, gas and geological exploration. It can increase bit life, drilling speed and well quality. There are several cutting teeth special fixed at both ends of the blades. In this way, this stabilizer is cutting bidirectional when drilling and pulling out, to achieve the effect of repairing and maintaining the wall of a well, making trajectory of well bore as possible as ideal condition, even preventing the phenomenon of dogleg. Especially when pull out, it always hard to pull out of the hole because of hole shrinkage etc. At this moment, the cutting function of back-reamer could eliminate hole shrikage phenomenon, thus to save time and costs for drilling.

Roller Reamer
Roller reamer is designed for various reaming operation. It can be used in hard formation or abrasive formation, in order to keep the standard hole size. When the bit size is under the standard size, it can ream the well bottom size to standard hole size. Whether drilling the vertical well or directional well, it can make the bit or casing come into the normal hole size. The features of roller reamer are small frictional resistance with well wall, strong abrasive resistance and long life.
Hardfacing of roller:
Type T: Soft formation Type F: Medium-hard formation Type B: Hard formation

Interchangeable Blades Stabilizer
SJ-TY Interchangeable blades stabilizer is the new generation production of integral blade stabilizer. It has sixteen diameters by changing the blads in different height and the spacers in different thickness. Its oriented and stability can be improved by changing the blades. It is an ideal tool for the drilling operation which has no based installation and located faraway place. We can change the blades quickly and easily, so that reduce the stock and delivery cost. All sizes stabilizers with this kind of design have been successfully used in various wells. Our SJ-TY interchangeable blades stabilizers are produced according to API and NS-1.

Hydraulic Adjustable Stabilizer
Hydraulic adjustable stabilizer is a new type downhole tool which have new and originality structure. In directional well drilling process, using the extended of bearing block to contact the wall of well. It will insure that the hydraulic variable diameter stabilizer worked with different drilling tools to increase and stabilize the hole angle. It is suitable for deviated and horizontal wells. The features are easy operation, small friction, stable drilling, easy screw off and smoothly tripping. It is an ideal stabilizer in directional well.
