The compact well drilling and workover winch with the automatic bit feeding device comprises a main motor, and the main motor is connected with an input shaft of a reduction gearbox through a coupler a; an output shaft of the reduction gearbox is connected with the left end of the roller shaft assembly through a coupler b; the right end of the roller shaft assembly is connected with the tooth clutch through a key b; and the tooth clutch is connected with the automatic bit feeding device assembly through a chain. The roller shaft assembly is provided with hydraulic disc type brake devices which are arranged diagonally on the two sides of the roller shaft assembly; the reduction gearbox is provided with an independent engine oil lubricating device. The reduction gearbox adopts two-gear gear transmission and can output a high gear and a low gear, and meanwhile, an automatic drill feeding device is arranged, so that working conditions required by well drilling and repairing can be completely met. The winch is compact in structure, easy to install, convenient to transport and complete in function, working efficiency of the winch is effectively improved, and drilling and workover operation time is shortened.
