The utility model discloses a drilling well leakage high-precision positioning device, and belongs to the technical field of well leakage positioning. Comprising at least one mounting cylinder and at least two drill columns, and the mounting cylinder is detachably mounted between the two drill columns; a placement cavity is formed in the mounting cylinder, a mounting hole is formed in the side face of the mounting cylinder, the mounting hole penetrates through the side face of the mounting cylinder, and the mounting hole communicates with the placement cavity; a detection assembly is mounted at the placement cavity; the detection assembly comprises a pressure sensor and a temperature sensor, and the pressure sensor and the temperature sensor are located on the two sides of the containing cavity and installed in the installation hole in a clearance fit mode. According to the drilling leakage high-precision positioning device, the multiple drill columns replace a traditional whole drill rod, the installation barrels with the detection assemblies are detachably installed between the adjacent drill columns, when one detection assembly is damaged, rapid replacement and maintenance can be achieved only by disassembling the corresponding installation barrel, the maintenance steps are simplified, and the maintenance efficiency is improved. Meanwhile, the standby cost is reduced.
