The invention provides a DDW high-precision depth domain well earthquake matching method. The method comprises steps of step 1, inputting earthquake data and earthquake geological stratums, and preprocessing the data; step 2, selecting a well side earthquake channel X of a target well, carrying out depth domain synthesis recording manufacturing to obtain Y, and carrying out synthesis recording sampling point selection by refereeing to the geological stratums; step 3, scanning the well side channels under the constraint of geological hierarchy; step 4, carrying out distance calculation point bypoint, and finding the point with the shortest distance between the synthesis recording sampling point; step 5, solving accumulated distances, and planning a shortest path; step 6, establishing a point-to-point corresponding well earthquake matching relation and calculating well earthquake error correction quantity; and step 7, establishing deviation constraint body correction earthquake data. According to the invention, by taking the well earthquake error influence factor quantity version as the restraint, dynamic depth planning similarity analysis between the depth domain well side earthquake channels and synthesis recording channels is performed, the well earthquake high-efficiency matching in the whole well section is achieved for the first time.
