A movable drill pipe lay-down machine for oil field drilling and workover comprises a drilling and workover platform, a left drill pipe vertical storage box, a grabber, a lay-down machine body, a right drill pipe vertical storage box, a track frame, a track base, a rotary frame, a transfer track frame and a ramp. The lay-down machine body can travel from the track frame to the rotary frame and then travel from the rotary frame to the transfer track frame, and thus the lay-down machine body is evacuated conveniently, a construction passage is available, and other work can be performed conveniently. The left side and the right side of the track base are each provided with two flat clamping blocks. The transfer track frame can be conveniently dismounted from the right side of the track base and then installed on the left side of the track base. The drilling and workover platform can be arranged more reasonably, so that construction is facilitated. An elastic pressing device is installed behind the grabber, and grabbed drill pipes can be concentric with a borehole when the grabber is centralized. The lay-down machine body is evacuated conveniently and rapidly in a time and labor saving mode, working efficiency is high, the labor intensity of operators is relieved, the rescue passage can be available in time, blowout accidents are prevented, and economic benefits and social benefits are remarkable.
