流量测井方法在抽水试验中的应用

Application of Flowmeter Logging Method in Pumping Test

流量测井技术不但能够验证钻孔抽水试验的数据,而且能够利用一次混合抽水试验资料,确定多个含水层的水文地质参数。比单纯的分层抽水有了质的改善,成倍地提高了工作效率,节约了成本。

Not only the data of drilling pumping test are validated by flowmeter logging, but also the multi - aquifer hydrogeological parameters are confirmed by the data of one mixed- layer puttying test in the hydrogeological exploration, so it is not suited to the current position for the hydrogeological evaluation by the single means. There is qualitative improvement by the method comparing with separate - interval pumping and previous hydro - logging which can calculate the mean value of amount of water and penetration coefficient, and so on. and aquifer qualitative data. As a result working efficiency is further increased and the cost is cut down.
