摘要
武威盆地儿马湖凹陷地质调查井武地1井钻井工程位于内蒙古自治区腾格里沙漠腹地,施工条件恶劣。上部第四系覆盖层主要岩性为黄色砂土和红色细砂,厚度大,松散易垮塌。针对武地1井钻井难点,从井场建设、钻井设备的选择、井身结构、钻井液优化等方面采取措施,为沙漠地区钻井施工积累了经验。
Wudi- 1 is a geological survey well in Ermahu depression of Wuwei basin and the drilling project is located in the hinterland of Inner Mongolia Autonomous Region Tengger Desert with bad construction conditions. The main lithologies of upper Quaternary overburden are yellow sand and red fine sand with large thickness, being loose and easy to collapse. According to the drilling difficulties of Wudi - 1, the measures were taken in site construction, drilling equipments selec- tion, casing program, and drilling fluid, the experience has been accumulated for drilling construction in desert area.
