What are the functions and structural characteristics of tubing centralizer?
I.Overview: Tubing centralizers are used in large dogleg deviated and vertical Wells to avoid or reduce wear between light tubing and casing. Two,use: The tubing centralizer is mainly used for tubing centralizer in inclined Wells of oil and water Wells. III.Structure: The tubing centralizer is mainly composed of a body and a rotary centralizer. IV.Features: 1.Machine-produced tubing centralizer can ensure the tubing is centered and reduce eccentric wear. 2.Simple structure,flexible rotation,small friction,good righting effect. 3.Use on both ends of the packer to reduce the friction damage of the wellbore wall to the rubber cylinder of the packer and extend the service life of the packer.

What are the common centralizers
Centralizers,also known as centralizers,are centralizers mounted on the casing's outer surface to ensure that the casing string runs in the center of the wellbore.The application of fuzzing in oil and gas drilling can improve the working stability of the bit and prolong the service life of the bit.Common centralizers mainly include rigid centralizers,integral centralizers and rolling centralizers,wheel centralizers,hinge centralizers,etc. 1.Integral centralizer According to the material forming form,the integral centralizer can be divided into:pipe integral stamping type and coil stamping type.Pipe integral stamping type,is a kind of circular steel pipe after cutting,wire saw,hydraulic molding and other processes,the whole process without welding.The coil stamping type is through cutting,rolling,wire saw,welding and other processes to solve the compression forming of a whole steel plate,allowing welding of the integral centralizer 2.Rigid centralizer Rigid centralizers can rotate and slide up and down the casing,or they can be fixed to a part of the casing with a set screw or a set ring.Rigid Centralizers and Elastic Support Rulers are a good choice when rotating the casing to improve displacement efficiency during vertical well cementing.In horizontal Wells,spring centralizers can no longer support heavy casing strings.If the casing in the cement seal section needs to be rotated.

What should be paid attention to during the installation and use of centralizer?
Centralizer is a kind of cementing tool,which is simple to manufacture,beautiful in structure,durable and strong in centralizer.It overcomes the shortcoming of the original welding centralizer which is easy to dissolder and is a kind of centralizer which can guarantee the cementing quality of drilling tools.There are many kinds of centralizers,including roller type,slider type,and automatic reversing type.Centralizers include tubing centralizers,sucker rod centralizers,casing centralizers,special tubing centralizers,metal sucker rod centralizers,nylon centralizers,etc.Centralizers of different structures and materials are suitable for different types of deviant wear Wells.The key technology of using centralizer to prevent eccentric wear is centralizer's installation position,spacing and quantity. There are four aspects to the installation and use of centralizers: 1.Principle of small stroke loss Depending on the sucker rod configuration,the centralizer should minimize the load on the slender sucker rod.It is recommended to install 4-10 pump hanger per 1000 m. 2.According to the quality of oil The centralizer adopts automatic sliding valve opening and closing structure,which can avoid scaling and paraffin formation on the body.However,paraffin formation should be avoided when installing this product. 3.Based on the curvature of the well In places where eccentric wear is serious,centralizer installation density should be appropriately increased to better centralize sucker rods.
