[0017] 如图1所示的空气压缩机抽水试验用气水混合器,包括通过连接杆一2和连接杆二10固定在钻井3内的出水管5,所述出水管5的上端安装有接水桶7,所述出水管5内通过连接杆三4和连接杆四9设置有风管6,所述风管6底部与出水管5底部之间的距离为3m〜5m,这是为了保证来自空气压缩机的气体能全部进入出水管5内的水中,如果管6底部与出水管5底部之间的距离小于3m,部分气体会通过出水管5下端进入出水管5与井壁之间,造成气体无效输入。 [0017] The air compressor 1 as shown in FIG water pumping test gas mixer, by a connecting rod comprising a connecting rod 2 and two outlet pipe 10 is fixed at 5 in the drill 3, the upper end of the outlet pipe 5 is mounted then the bucket 7, the outlet pipe 4 by a connecting rod and three four connecting rods 9 is provided with a duct 6 5, the duct 6 and the distance between the bottom of the bottom outlet pipe 5 3m~5m, which is to ensure the gas can all air from the compressor into the water in the outlet pipe 5, if the distance between the bottom of the tube 6 and a bottom water outlet pipe 5 is less than 3m, part of the gas will pass into the outlet pipe 5 between the outlet pipe 5 and the lower end wall, causing gas invalid input. 如果管6底部与出水管5底部之间的距离大于5m,则表明出水管5下入深度太大,不符合生产要求,管6底部与出水管5底部之间的距离3〜5m时,空气压缩机的气体能全部进入出水管5的水中,且不会造成气体无效输入,起到很好的效果。 If the distance between the bottom of the tube 6 and a bottom water outlet pipe 5 is

the duct 6 is connected to the outside of the air compressor, compressed air enters through the air duct 6, and the gas through hole 612 is mixed with water in the outlet pipe 5 through the duct, since gas duct 6 from the side walls and the gas flowing out of a plurality of through holes 12, so that the mixed gas and the water can be sufficiently contacted and mixed faster, so that the water within 3 lift drilling height increases, the outlet pipe 5 water is rapidly lifted from the water, and then flows in the outlet pipe 5 7。 7. 采用该空气压缩机抽水试验用气水混合器,大大缩短了气水混合的时间, 提高了试验的效率。 The air

pipe 5 or less, to ensure that its lower end into the gas outlet pipe 5 the following. 测量水位的方法是用一个专用的金属水文探棒,所述探棒用一个导电的刻度绳与外部的电阻率记录表连接,使用时,将探棒从测管内下放,当探棒与水面接触后,电阻率降低,地面的电阻率记录表指针摆动,即可记录水面深度,再通过抽水前记录的一个原始水位埋深与抽水过程中测量的水位埋深即可得到抽水试验的降深S,再通过以下公式计算渗透系数K和影响半径R: The method of measuring the water level is to use a special hydrological metal probe, with said probe resistivity scale rope with a conductive external connection record table, in use, the measuring probe decentralized from the inner tube, in contact with the water surface when the probe after, reduced electrical resistivity, surface resistivity of the recording table pointer swings to the recording surface of the water depth, and
