Drill stabilizers are important tools for controlling wellbore trajectory parameters in drilling engineering. They are used to stabilize drill strings during oil, gas, and geological exploration drilling. Their effective stabilizing action increases drill bit life, improves drilling speed, and enhances wellbore quality. Overall stabilizers can be divided into two types: helical stabilizers and straight-blade stabilizers.

Gimbal with positive and negative stroke stabilization
A positive and negative slip stabilizer is an important tool in drilling engineering to prevent well deviation. It increases drill bit life, improves drilling speed and wellbore quality through effective stabilization. Positive and negative slip stabilizers have several cutting teeth specially set at the upper and lower ends of the working section. During drilling and tripping, it can play a two-way cutting role, smoothing the wellbore wall, making the well trajectory as close to the ideal state as possible, and preventing dog-leg phenomenon.

The replaceable sleeve stabilizer consists of an integral mandrel and sleeve, functioning as an integral spiral stabilizer. It can adapt to different wellbore diameters by replacing various centralizer sleeves, or extend the stabilizer's service life by replacing it with the same centralizer sleeve. The centralizer sleeve and mandrel are connected via tapered threads, ensuring a more reliable connection between the stabilizer centralizer sleeve and the mandrel, and making replacement and assembly more convenient.

A non-rotating stabilizer is a downhole tool used in oil drilling operations. Its primary function is as a conventional stabilizer during drilling, but it can also help reduce torque. A non-rotating stabilizer consists of a mandrel and a sleeve; the sleeve can be replaced if worn.

Hydraulic variable diameter stabilizer
In directional drilling, the hydraulic variable diameter stabilizer utilizes the extension of the support head to achieve full eye contact, thereby ensuring that the hydraulic variable diameter stabilizer meets the requirements for increasing and stabilizing the angle in different BHA combinations in directional wells.

SJ-TY type replaceable blade variable diameter stabilizer
The SJ-TY type replaceable wear pad stabilizer allows for convenient wear pad replacement, and by changing different heights of wear pads and different thicknesses of shims, 16 different diameters can be obtained with the same body. Its enhanced profile and interchangeable wear pads greatly improve the stabilizer's guidance and stability. This is an ideal tool for operations in remote areas or areas lacking infrastructure, allowing for quick and easy wear pad replacement on the well site.
