利用地震勘探研究砂岩型铀矿成矿环境

Using Seismic Exploration Technology to Study Metallogenic Geological Environments of Sandstone-type Uranium Deposit

地震勘探广泛应用于沉积盆地油、气等能源矿产勘查中,但在砂岩型铀矿找矿中的应用相对较少。本文从砂岩型铀矿成矿条件及地震勘探基本工作原理出发,系统地总结了地震勘探在分析研究与砂岩型铀矿相关的盆地构造演化、岩性-岩相等成矿环境的作用。认为地震勘探在识别地下断裂、查明基底起伏、划分岩相及圈定容矿主砂体等方面具有较突出的优势。并着重强调对石油系统地震等资料的利用及再解释,有利于提高工作效益,减少勘探成本。

Seismic exploration technology has been widely applied in oil and natural gas exploring in sedimentary basins,but it have seldom been applied in sandstone type uranium deposits.In this paper,according to the metallogenic conditions of sandstone-type uranium deposits and the basic working principle of seismic exploration,summarizes the role of the seismic exploration in the analysis of metallogenic environment,such as tectonic evolution of basins and lithology-lithofacies related to sandstone-type uranium deposit.Identify that seismic exploration has more prominent advantages in identification of subsurface faults,clarification of basement variation,dividing facies and delineation of ore-bearing sand body.And to highlight the use of seismic data on the oil system and reexplain,help to improve work efficiency,reduce exploration costs.
