The3D seismic exploration technology is a set of physics, mathematics, computer scienceis a comprehensive application technology, its application to image the subsurface target moreclear, more reliable location prediction.The3D seismic exploration technology from2Dseismic exploration is gradually developed, is the most important method in geophysicalexploration, but also the current global oil, natural gas, coal and other underground naturalmineral exploration technology。Geological exploration staff using3D seismic data of highquality oil and gas prospecting, the Gulf of Bohai, the recent discovery of Nanpu oilfield inChina, Sichuan Puguang gas field in Tarim basin gas field,3D seismic exploration technologythanks to the high precision.Seismic data interpretation is the process of the earthquake information processing intogeological results, including the use of the wave theory and geological knowledge, combinedwith geology, drilling, logging and other information, make the structure interpretation,interpretation, interpretation of lithology and hydrocarbon detection and comprehensiveinterpretation, draw the relevant maps, petroliferous evaluation of work area, the drillinglocation。In this paper, the high precision fine seismic interpretation work, using Landmarkinterpretation system and Jason, Geo-Office inversion software, in-depth interpretation andresearch of3D seismic data interpretation, from the structure, lithology prediction, oil and gasenrichment regularity of distribution characteristics of the ADX area of structural traps,fracture of the longitudinal, transverse development characteristics, plane distributioncharacteristics of sandstone reservoir, the influence of oil and gas enrichment factors。In theinterpretation process, using the technology of fine structural interpretation, correlationtechnology, horizontal slice technique,3D visualization technique, inversion technology.Finally, this paper classify the results of the analysis, the oil and gas accumulation and thelower part of the focus of exploration, has provided the powerful technical support and reliableseismic geological results for seismic exploration work in this area.
