摘　　要：以YR-3井为例,阐述了牛驮镇地热田从下伏石灰岩-白云岩完整地层钻取地热水时的多级成井结构及固井技术。该技术可有效地克服因地层漏失造成的孔壁坍塌及因设备能力偏小而造成的固井困难。经多眼井施工证明,该方法是牛驮镇地热田及类似地层地热井施工的有效方法。With the example of YR - 3 well, the paper discussed the muhilevel well completion structure and cementing technology of drilling for geothermal water in underlying limestone-dolomite complete formation of Niutuozhen geothermal field. With this technology, borehole collapsing caused by circulation loss and cementing difficulties due to low equipment capacity can he effectively solved. Construction of several wells proved that it is a successful and effective method for Niutuozhen geothermal field and the similar ones.
