In the early stage of the exploration project of sandstone type uranium deposit in the south end of Daqing placanticline,many scattered industrial holes were found by using the drilling data of the oil field,which were proved by drilling.In order to further expand the prospecting results,the authors carried out seismic exploration.According to the characteristics of the buried depth of the strata in the working area,the reasonable acquisition parameters were selected,the stratigraphic division of the working area was unified,the sand body was delineated,and then the ancient river course was inferred,the reservoir problem in the exploration of sandstone type uranium deposit was solved,and good results were obtained.It is proved that seismic exploration can be used as the main method in the search for favorable reservoirs in sandstone type uranium exploration.
