在探矿钻井或水文地质勘探钻井中抽水时,往往要降低几次水头求得平均涌水量值。水位资料的取得要下专用观测管进行水位观测,这样会花费不少人力、物力和财力,同时也要增加工人的劳动强度。而且所得水位资料的误差甚大;如果用物探测井的注入 In prospecting drilling or hydrogeological exploration drilling pumping, often to reduce the head several times to obtain the average water inflow value. Water level data acquisition Dedicated observation tube for water level observation, this will spend a lot of manpower, material and financial resources, but also to increase the labor intensity of workers. And the resulting error of the water level data is very large; if the object detection wells injection
