Profile: Shaanxi Senwell Drilling Equipment Co., Ltd. offers petroleum mechanical equipment and oilfield equipment. Our drill pipe is used as the major part of drill stem. Our unbalanced spiral blade stabilizer is based on the structural unbalanced principle. It produces a centrifugal force towards the weighted side during the rotation of drill string. This would produce a large impact restoring force to straighten well-bore gradually. Therefore both single-spiral blade stabilizer, and multi-spiral blade stabilizer are ideal anti-inclination tools. Float valve stabilizer is mainly used in near bit type stabilizer for preventing the unit from borehole deflection. The float valve stabilizer will automatically shut off inside the bore of the tool to avoid accidents.
