The stabilizer belongs to the cementing tool, which is simple to manufacture, has a beautiful structure, is sturdy and durable, has a strong straightening force, overcomes the shortcomings of the original welded stabilizer that is prone to detachment, and is a stabilizer that can ensure the quality of drilling and cementing.
There are many types of stabilizers, which can be divided into roller type, slider type, automatic reversing type, etc. according to their structure. Centralizers with different structures and materials are suitable for oil wells with different types of eccentric wear. The key technology for using stabilizers to prevent eccentric wear is the installation position, spacing, and quantity of stabilizers.
Drilling stabilizer is a device used to control the drilling direction and ensure the integrity of the borehole during the drilling process. However, there are few reports on the method of using drilling stabilizer to prevent drilling jamming. Therefore, the stabilizer anti collapse and correction technology proposed in this article has great reference value and promotion value for geological drilling engineering
Principle of stabilizer
Centralizer is a new type of oil production tool used in oil field pumping wells, which can improve the pumping efficiency of oil pumps; It adopts a sliding valve automatic opening and closing structure, connected to the sucker rod. When the sucker rod moves down, the slide valve opens the oil passage on the stabilizer body when it moves up, and when the sucker rod moves up, the slide valve closes the oil passage on the stabilizer body when it moves down. Thus, by lifting the liquid column in sections, the load on the pumping rod and pump can be reduced in sections, reducing pump leakage, minimizing the elastic elongation deformation of the pumping rod, reducing stroke loss, thereby improving the effective stroke of the pumping pump, increasing the filling amount of the pump barrel, and improving pump efficiency.
