The utility model belongs to the technical field of petroleum drilling, and particularly relates to a sampling and lifting device for petroleum drilling. The left end and the right end of the lower surface of the workbench are each fixedly provided with a set of supporting frames, the left side of the upper surface of the workbench is fixedly provided with a motor, the middle of the right surface of the motor is rotationally provided with a rotating shaft, and the middle of the outer surface of the rotating shaft is fixedly provided with a take-up reel. A plurality of groups of electric push rods are matched with a piston to form a plurality of groups of sampling pipe structures, so that petroleum liquid mixtures at different depths can be collected in the descending process of petroleum drilling, the working efficiency is improved, and repeated lifting and sampling are avoided; and large sand and soil can be filtered, the situation that many impurities are sucked in the material storage sleeve is avoided, a
