Seismic prestack depth migration is a key technology in hydrocarbon exploration，development，research and production. Based on study on prestack depth migration technology research and its application achievement and experience in Shengli oilfield，characteristics and practical prestack depth migration and modeling techniques were introduced firstly according to surface and subsurface geologic conditions of the study area，which could be used together in application to different study area and different geologic task according to the actual need. And secondly，effects on the prestack migration technique were analyzed based on the idea of integration of acquisition，processing and interpretation，and then the corresponding countermeasures were put forward. Finally，several industrial applications of the technique to typical examples in Shengli oilfield were used to verify effectiveness of integration solution of prestack depth migration technology for hydrocarbon exploration. A set of“depth domain+”prestack depth migration technology has been summarized to promote further development of the seismic technique in domain of depth and to provide better service for oilfield exploration and development.
