Formation overlap-denudation line recognition method based on iteration earthquake DNA detection

The invention provides a formation overlap-denudation line recognition method based on iteration earthquake DNA detection. The formation overlap-denudation line recognition method includes the steps of firstly, inputting a three-dimensional seismic data body and unconformable surface layer bit data; secondly, obtaining target seismic data; thirdly, converting the target seismic data into character data; fourthly, setting search parameters; fifthly, using wave group feature change positions meeting the search parameters as overlap-denudation points, and recording the overlap-denudation points; sixthly, outputting overlap-denudation lines, and obtaining the distribution of the overlap-denudation lines on a plane. The formation overlap-denudation line recognition method is based on iteration earthquake DNA detection, the accurate and efficient detection result can be obtained, and by means of the method, the labor intensity of geological research personnel can be lowered, and the exploration deployment quality and benefits can be improved.
