摘要
针对腾格里沙漠南缘严重缺水的现状,开展了常规电阻率测深工作。综合地质、水文地质、电性参数等特征对测深曲线进行定性、定量精细解释,总结出电阻率在25Ω·m左右的新近系地层为砂岩、砂砾岩相对较厚,泥岩相对较薄区段,是该区域寻找碎屑岩类裂隙孔隙水的目标层位。钻探结果表明,轻便、经济的常规电阻率测深法在阿拉善干旱荒漠严重缺水区可以取得显著的找水效果。
In view of the serious water shortage at the southern edge of Tenggli Desert,the authors carried out conventional resistivity sounding. The resistivity sounding curves are interpreted qualitatively,quantitatively and in detailed by comprehensive geological,hydrogeological and electrical characteristics. It is concluded that the Neogene strata with resistivity of about 25 Ω·m are sandstone,sand gravel is relatively thick and mudstone is relatively thin,suggesting that this horizon is the target horizon in search for cranny pore water of clastic rock in this area. The drilling results show that the conventional resistivity sounding method,which is portable and economical,can be used to find groundwater in the arid desert area of Alxa with severe water shortage.
