| 摘 要： | 鄂尔多斯盆地西南缘，白垩系志丹群的6个岩组分布俱全，地质与水文地质信息丰富。介绍了位于该区的具有勘探与长观双重意义，集全孔段取心、四层分层抽水试验、三层长期观测于一井的B5号井的井身结构设计和施工工艺。通过B5号多层位超深试验观测井的施工，证明了一井多用途的经济性和可能性，积累了多层位超深观测井施工经验，为整个鄂尔多斯盆地水文地质调查起到了示范作用。

| Abstract: | In the southwestern margin of Ordos basin, 6 Cretaceous conglomerate groups were distributed with abundant geology and hydrogeology information. The paper introduced the B5 well in this area about the well structure design and the construction technology, which could be used for prospecting and long-term observation, coring and pumping test. This well construction proved the possibility of multipurpose by a single well and played demonstration functions for hydrogeology survey in Ordos basin. |
