AI Technical Summary
Technical Problem
During drilling, the mud inside the drill pipe gushes out due to gravity when the drill string is pulled out, causing mud to scatter and splash, contaminating the drilling platform and drilling workers, posing environmental and safety hazards.
Method used
A simple blowout prevention device for drilling was designed, including a blowout prevention tank and a recovery tank. The mud is guided into the recovery tank by the mud baffle and grinding disc of the blowout prevention tank to prevent splashing, and is recovered into the mud tank through the discharge port.
Benefits of technology
It effectively controls mud gushing, protects the drilling platform and workers, facilitates mud cleaning and reuse, and reduces environmental pollution.
