1.Mechanical sleeve stabilizer
Mechanical sleeve centralizer is one of the most common sleeve centralizers, which mainly consists of a bracket and two movable fixtures. The fixture can be adjusted according to the size of the wellbore and can accommodate sleeve of different diameters. It usually uses manual or semi-automatic control and requires personnel operation to complete the straightening of the sleeve. The mechanical sleeve stabilizer has the characteristics of simple structure and high reliability, but the disadvantage is that the operation process is cumbersome and the efficiency is low.
2.Hydraulic sleeve stabilizer
Hydraulic sleeve stabilizer is a type of stabilizer that uses liquid as its power source. Its structure is relatively complex, consisting of hydraulic cylinders, brackets, and fixtures. The hydraulic sleeve stabilizer has a wide range of applications, not only can it adapt to various diameters of sleeve, but also can straighten longer sleeves. And its straightening efficiency is high, with less dependence on personnel, which can improve work efficiency.
3.Pneumatic sleeve stabilizer
Pneumatic sleeve stabilizer is one of the common sleeve stabilizers, which uses gas as a power source and has the characteristics of high work efficiency and low personnel participation. The structure of the pneumatic sleeve stabilizer is relatively simple, consisting of a pneumatic cylinder, bracket, and fixture. It can adapt to sleeve of different diameters and lengths, and can also adapt to complex well environments, with high adaptability and efficiency.
4.Electric sleeve stabilizer
Electric sleeve centralizer is similar to hydraulic and pneumatic sleeve centralizer, but its power source is different. It uses an electric motor as the power source. The electric sleeve stabilizer has the advantages of simple operation, high efficiency, and wide adaptability, but its structure is relatively complex and requires special electrical support, making it relatively inconvenient to use.
