Professional Casing Centralizers Manufacturer from China
The manufacturer of Composite Centralizer will take you to understand: the background status of the centralizer
The Composite Centralizer manufacturer tells you that the centralizer is a tool for stabilizing downhole drilling tools and preventing deflection. A device connected to a section of drill pipe string close to the coarse-diameter drilling tool to stabilize the drilling direction is an important tool for preventing well deviation changes in oil, natural gas and geological exploration drilling projects.
The manufacturer of Composite Centralizer told you that centralizers were first used in 1928. In the 1960s, they realized the important role of multiple centralizers in theory and put them into practice. After that, they conducted a lot of theoretical research and achieved fruitful results. It is still widely used in drilling construction.
The Composite Centralizer manufacturer tells you that in China, deep wells and ultra-deep wells account for a large proportion of pre-exploration wells and production wells in certain exploration areas, and domestic drilling tool manufacturers have also developed and developed deep well tools accordingly. The Composite Centralizer manufacturer tells you that due to the complex downhole working conditions, during the drilling process, ordinary centralizers have a short working life in the downhole and often fail accidents. The Composite Centralizer manufacturer tells you that improving the downhole working life of the centralizer is a key research topic for domestic oilfield companies and drilling tool manufacturers.
The Composite Centralizer manufacturer tells you that since the use of triple helix centralizers in my country's oil and gas fields in 1983, there has been basically no change in its structure. Most of the existing three-spiral centralizers adopt a certain number of cemented carbide blocks inlaid on the spiral bar to increase the surface wear resistance. However, the falling off of the cemented carbide block is very serious. After falling into the well, it affects the drilling speed, reduces the life of the bit, and increases the drilling cost. Therefore, it is possible to optimize the design of the spiral structure, the body structure and the shape of the spiral groove of the existing centralizer to improve the load condition of the spiral part of the centralizer, thereby increasing the fatigue life of the centralizer. The Composite Centralizer manufacturer tells you that the newly developed centralizer is mainly developed to improve the wear resistance of the working section and the connection reliability of the threaded joint.
Steel Solid Rigid Centralizer is generally used in regular holes without neck shrinkage or large belly section. When the well diameter reaches a certain level, no amount of rigid centralizers can make the casing reach the desired medium.
