摘要
大庆长垣南端砂岩型铀矿勘查项目前期利用油田钻孔资料发现了众多零散的工业孔,并钻探证实。为了进一步扩大找矿成果,开展了地震勘探。针对工作区地层埋深特点选择了合理的采集参数,利用地震成果并结合测井数据,统一了工作区的层位划分,圈定了砂体,进而推断出古河道,解决了砂岩型铀矿勘查中的储层问题,取得了很好的成果。地震勘探可作为砂岩型铀矿勘查寻找有利储层的主要方法手段。
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.
