While drilling reamer is a downhole tool used in oil drilling engineering, which has the features of blade opening or retractable, replaceable and adjustable size, and wider reaming range.
Main functions:
- Expanding hole diameter: Existing holes can be expanded to a specific size according to design requirements to meet the needs of subsequent operations such as running larger casing sizes.
- Wall trimming: The irregular wall is trimmed to make it smoother and more regular to facilitate subsequent drilling operations and ensure that casing can be run smoothly and well cemented.
Working principle: The drilling fluid drives its internal power mechanism, drives the cutting tool to rotate, so as to cut and break the wall rock to achieve reaming function.
It is helpful to improve drilling efficiency and borehole quality, and plays an important role in the complex process of oil drilling.
