AI Technical Summary
Traditional drilling wellbore cleaning methods are inefficient and may damage the wellbore structure, posing safety risks.
The machine employs a negative pressure adsorption drilling wellbore dredging device. The stable rotation of the rotating pipe is achieved through the cooperation of the drive gear and the driven gear. Combined with high-pressure water spray and rotating scraper, the silt is removed, and the mud is rapidly sucked out using the annularly distributed suction ports.
It improves the efficiency of well cleaning, avoids damage to the well structure, and ensures the safety and continuity of the dredging process.
