摘　　要：工区位于东准噶尔盆地东缘,气候干燥炎热,降水稀少。区内地表水主要接受大气降水补给,其次是构造裂隙水。然而浅地表水质硬度大,为碱性,不宜饮用。为满足当地工业及生活用水的需求,在该区开展了双频激电法找水工作。在本次工作中,数据采集选择梯度三极激电测深装置,数据处理选用IPInv1.6激电反演软件。最终结合激电测深反演成果、区域水文和地质资料进行综合解译,推断含水构造破碎带一条,设计4个探水孔,总出水量2160吨/天,并且水质较好。因此该方法解决了当地工业和生活用水问题。The working area is located on the east margin of East Junggar basin, where it is dry, hot and lack of water. The surface water is mainly replenished by atmospheric precipi- tation, and partly by the structural fissure water. However, the shallow surface water is hard water with high alkaline, which is undrinkable. In order to meet the demand of the lo- cal industry and domestic water, the dual--frequency induced polarization prospecting work is carried out in this area. We apply gradient pole--dipole sounding observation device and the IP inversion software IPInvl. 6 to data collection and data processing respectively. Fi- nally, the comprehensive interpretation is given out by the combination of IP sounding in-version results, hydrological and geological data. The result shows that there is a water bearing structure in this area. We design 4 water exploration wells in the survey lines, which can raise the water yield of 2160 tons/day with good quality. Therefore, the problem of the local industrial and domestic water is solved by this method.
