Well cleanliness condition analysis method and device and computer storage medium

The embodiment of the invention discloses a well cleanliness condition analysis method and device and a computer storage medium. After a to-be-monitored well is determined, historical drilling data of the to-be-monitored well is obtained, and a corresponding hook load well depth modeling graph is constructed according to a preset comprehensive friction resistance coefficient scale and the historical drilling data of the to-be-monitored well; according to torque friction resistance data actually measured at each target measurement site in the to-be-monitored well, actual measurement parameter points corresponding to each target measurement site are marked on the hook load well depth modeling map; according to the standard friction resistance coefficient curve, an actual friction resistance coefficient corresponding to each actual measurement parameter point is determined. according to the actual friction resistance coefficients of the current measurement site and the previous measurement site, the cleanliness
