There are generally different structural forms of ssleeve stabilizer, including rigid stabilizers and elastic stabilizers, which can be selected according to specific operational needs. It includes two types: spiral and straight edge, suitable for various geological formations and process requirements, and widely used.
Stabilizer, also known as centralizer, is a tool for stabilizing downhole drilling tools and preventing deflection, a device connected to a section of drill pipe string close to the large-diameter drilling tool, to stabilize the drilling direction. It is also an important tool for preventing well deviation changes in oil, natural gas and geological exploration drilling projects.
The main functions are as follows:
