Channel expansion
It provides multiple channels to facilitate various operations during drilling. These channels can be used to inject drilling fluid, conduct logging operations, install downhole tools, etc. Taking the injection of drilling fluid as an example, a channel of the casing spool can smoothly transport the drilling fluid to the well, cool and lubricate the drill bit, and carry the cuttings to the ground to ensure the smooth progress of drilling work.
Strong pressure bearing capacity
Casing spool is generally made of high-strength metal materials, such as alloy steel, with excellent pressure resistance. In high-pressure oil and gas wells, it can withstand the huge pressure from deep in the formation to prevent oil and gas leakage and blowout accidents. In some deep-sea oil wells or deep-layer land oil wells, the formation pressure may reach tens of MPa or even higher. The casing spool can stably withstand these pressures to ensure the safety of the wellbore.
Good sealing performance
It has a special sealing structure inside, which can effectively seal the connection between each channel and between the channel and the casing through rubber seals or metal seals. This good sealing performance can prevent the leakage of drilling fluid, avoid mutual interference between different fluids, and also prevent the upward flow of oil and gas in the formation, ensuring the safety and stability of the drilling and production process.
