INTEGRAL SPIRAL BLADE STABILIZER 1. General overview
Drill stabilizer is a very important tool to prevent well deviation during drilling operation. It can also increase the service life of the drill bit, increase the drill speed and the well quality, and make the wellbore smooth, which can reduce the complex situation. It can also build and drop well deviation in the directional drilling.
2. StructureDrill stabilizer can be divided into integral stabilizer (including integral straight blade stabilizer and integral spiral blade stabilizer) and replaceable sleeve stabilizer. According to the different using position, the stabilizer can be divided into near bit type stabilizer and string type stabilizer. The structure is shown below:
