摘　　要：施工焦作市修武县水源地项目1#井中,785m见奥陶系顶面,井深900m时未发现含水层,经双方协商延伸到1 000m,在909.10m～911.86m,泥浆消耗1m3/h;916.5m～918.68m,泥浆消耗0.8m3/h,完井后,试验抽水水量3m3/h,经注焦磷酸钠、拉活塞,水量没有增加,但经两次注盐酸洗井处理后,水量激增为100m3/h,动水位68m,远远满足了合同要求,使得该井顺利交接。During the construction of Xiuwu County water head site No.1 well, encountered the top of Ordovician System at the depth of 785m, and no aquifer has found above 900m. After negotiation of both sides agreed extend the drilling to 1000m. Between the depth of 909.10m-911.86m mud loss is 1m^3/h; 916.5m- 918.68m is 0.8m^3/h, after the well completion, tested capacity is 3m^3/h and no water capacity increasing after sodium pyrophosphate injection and piston shuttling processing, but after two times of hydrochloride acid cleanup, water yield is sharply increased to 100m3/h, hydrodynamic level 67m, preponderated over contract request, so as to hand over the well favorably.
