青海花土沟地区砂岩型铀矿钻探施工技术研究

收集柴达木西北缘青海油田花土沟地区以往钻孔资料,在优选的有利施工地段开展砂岩型铀矿钻探施工。文章详细介绍了在该地区施工的钻进工艺方法及复杂工况处理,总结了在该地区钻探施工技术及经验。根据柴达木盆地可地浸砂岩铀矿钻探钻遇地层多为复杂地层的实际情况,提出应大力加强该领域的钻探技术研究,尽快进行钻探设备的配套匹配,提高我国地浸砂岩铀矿钻探的水平。

Brief discussion on drilling technology for sandstone type uranium in Huatugou area, Qinghai

The drilling data of Huatugou area in Qinghai oilfield were collected, and the drilling of sandstone-type uranium deposit was carried out in the preferred favorable construction section. This paper introduces in detail the drilling technology and treatment of complex working conditions in this area, and summarizes the drilling technology and experience in this area. According to the fact that most of the strata drilled for in-situ leachable sandstone uranium deposit in Qaidam Basin are complex strata, it is proposed that the drilling technology in this field should be strengthened, matching of drilling equipment should be carried out as soon as possible, and the drilling level of in-situ leachable sandstone uranium deposit in China should be improved.
