Audited Supplier The roller resin centralizer is made by polymerizing high-temperature and high-pressure one-time integrated casting in a mold, and is widely used in various oil wells and gas wells.
The overall line of the resin centralizer is smooth and smooth, and it is used for the centering of the casing in the process of high-angle well and horizontal well completion. It can reduce the sliding friction resistance of the casing when entering the well wall and can effectively reduce the lower The casing is the frictional resistance.
In addition, the spiral groove also has a self-cleaning function, which can change the force state of the casing string in the resistance, ensure the smooth running of the casing during the construction process, reduce the weight, and correspondingly reduce the burden on the pipe, which is beneficial to the product. Keeping the tube centered in the casing improves safety.
