      The multifunctional scraper is a new type of scraper that can be used as a general non-rotating fixed scraper or as a rotatable scraper. In addition to conventional cleaning operations, if an obstruction is encountered midway, the downhole string should be stopped, the wellhead should be flushed, and a certain upward force should be applied to shear the shear pin and enter the rotating linkage mode. Then, according to the actual situation, the unlocking operation can be carried out, such as providing a certain torque, pressing down, circulating, and impacting until the normal operation is restored, and then the downhole string can be continued.
