Well Control Equipment-API 6A Casing Head

The casing head has the following advantages:Supporting casing string: providing stable support for each layer of casing, bearing the weight of the casing string, preventing it from sinking or displacement, and ensuring the vertical stability of the wellbore, which is particularly critical in deep wells and ultra-deep wells, ensuring that subsequent drilling and mining operations can be carried out safely and accurately, and avoiding accidents such as wellbore collapse caused by unstable casing.Sealing and leak prevention: through a reliable sealing structure, the annular space between the casings is effectively sealed to prevent the leakage of formation fluids at the casing connection, prevent oil and gas from rising, reduce resource waste and environmental pollution risks, maintain the stability of the well pressure system, ensure safe production, and avoid damage to the oil layer caused by the mutual cross-flow of fluids in different pressure layers.Pressure control and monitoring i…
