摘要
多分层精细化抽水试验正在成为水文勘探中一种不可或缺的手段,在多分层精细化抽水试验中需要多次进行抽水系统的下放和调整。作为试验关键环节,抽水系统能否顺利和准确下放至目标层位决定了后续抽水试验的质量。通过具体抽水项目,对多分层精细化抽水钻孔成井施工及抽水系统下放工艺进行了总结和研究。
Multiple stratified pumping test is becoming an indispensable means in hydrologic exploration,in which the pumping system needs to be lowered and adjusted for many times.As the key link in the test,the quality of the subsequent pumping test is determined by whether the pumping system can be smoothly and accurately lowered to the target horizon.This paper summarizes and studies the multiple stratified pumping well construction and pumping system lowering process through specific pumping project.
