摘　　要：介绍了吐哈三塘湖油田牛 10 2井利用泡沫流体以欠平衡钻井方式钻水平井段的钻井设计及施工情况。将欠平衡钻井、水平井钻井技术两种工艺相结合并且成功应用在牛 10 2井。着重论述了水平井段欠平衡钻井负压差值的选择依据 ,以及泡沫流体各参数的设计方法。该项技术在牛 10 2井的成功实践为今后同类条件油田的勘探开发提供了宝贵的经验和借鉴。The paper introduced the design and executive situation of horizontal part in well Niu 102 in Santanghu oilfield.This is unprecedented in China that UBD (underbalanced drilling) technique with foam was applied in horizontal well.How to select the proper different pressure of UBD in the horizontal part of the well was discussed in this paper,as well the design of foam parameter.The success of this kind technique provides the basis and the reference for the exploration in similar oilfield.
