The purpose of a casing centralizer is to facilitate running casing to the desired depth and to assist in centering the casing in the wellbore. One of the main objectives of centralizing a casing string is to facilitate a good cementing, thereby isolating fluids from different zones.
*Features*
1.The Semi-Rigid Centralizer outside strips are heaving, which can be contracted by a certain pressure, so that it can be prevented in the next to the hole of the hole to get stuck, to ensure that the normal into the well.
2.Compared with the spring bow centralizer, the semi-rigid centralizer has obvious advantages, which has the advantages of simple structure, safe and reliable, high strength, convenient operation and so on. Can be widely used in straight wells or high angle well casing construction operations, in vertical wells if cementing requirements of rotating casing to improve displacement efficiency, then semi-rigid spiral casing centralizer is the only choice.The semi-rigid centralizer compare with the rigid centralizer has obvious advantages of simple structure, strong adaptability and can be compressed
3.From 4 -1/2" to 13- 3/8" all kinds of casing and borehole series. There are four to eight strips, according to different hole size, the centralizer has a variety of sizes to choose from. When used, the centralizer can freely rotate and slide on the casing, and can also be fixed in the casing by a locator or fixed screw. Scraping mud cake removal and cleaning wall and in the cement injection to the cement slurry flow and improve the displacement efficiency, in deviated and horizontal wells, boosting the casing in the casing into the well, the casing is centered, is to improve the cementing quality is one of the important measures.
*About Warehousing, transportation and maintenance*
1.Product should be stored in flat, dry warehouse. All parts should be kept properly to prevent rain, sun and water erosion.| Casing Size (in/mm) | Hole Size (in/mm) |
