What are the types of stabilizers for petroleum drilling tools based on their functional characteristics and application scenarios

The stabilizer of petroleum drilling tools plays an important role in preventing wellbore deviation changes in petroleum, natural gas, and geological exploration drilling engineering. According to their functional characteristics and different application scenarios, stabilizers can be divided into the following types:
1. Rigid stabilizer
Both spiral and straight edged forms can be made into long or short shapes to adapt to different geological formations and process requirements. This is the most widely used type of stabilizer.
2. Non rotating rubber sleeve stabilizer
The advantage of not rotating with the drill string in the well is that it does not damage the wellbore and is safe to use, but its service life is low and its application range is limited.
3. Spherical stabilizer: A stabilizer with a special shape that may be used for stable operations under specific drilling conditions.
4. Efficient wear-resistant stabilizer: Special treatment is applied to the working surface on the basis of ordinary stabilizers to improve wear resistance and impact resistance, making it more suitable for abrasive formations.
5. Multi functional and efficient wear-resistant stabilizer: It not only has the characteristics of high efficiency and wear resistance, but may also have other additional functions, such as lifting short joints.
In short, there are various types of stabilizers for petroleum drilling tools, each with its unique structure and functional characteristics. When choosing a stabilizer, it is necessary to consider the specific drilling conditions, formation characteristics, and process requirements comprehensively. Meanwhile, with the continuous development of drilling technology, new types of stabilizers are constantly emerging to meet more complex and diverse drilling needs.
