For wellbore quality issues caused by wellbore steps, keyways, etc., although drilling and post drilling reaming can solve them
It is due to the high number of trips and low efficiency, while the micro reamer while drilling can eliminate wellbore steps, reduce trips and improve efficiency
It has significant advantages in high drilling efficiency and other aspects.
Introduction to micro reamer while drilling:
The drilling micro reamer adopts an eccentric structure, with a simple tool structure, no moving parts, and a diameter ratio
The drill bit size is small, but after drilling, it is slightly larger than the original wellbore, forming a smooth wellbore to ensure later tripping, electrical logging
Safe and smooth operations such as running casing.
Characteristics of micro reamer while drilling：
Eccentric structure: The diameter is smaller than the size of the drill bit, but slightly larger than the original wellbore after drilling;
Spiral blade: ensuring the protection of cutting teeth when passing through the casing, with reliable stability and durability;
Dual cutting structure: able to achieve forward hole expansion and reverse drilling;
Integrated structure: There are no moving or welding parts, and there is no risk of tool components falling into the well.
Helps to eliminate or minimize slight dog legs, forming a smoother wellbore trajectory;
Stirring the rock debris bed to improve the cleaning effect at the bottom of the well;
Eliminate short tripping and tripping;
Eliminate unnecessary well drilling operations;
No temperature, drilling speed or other restrictions.
