【摘要】 在分析抽水试验时,使用抽水井的降深数据必须消除井损。本文研究了井损的消除方法。通过带观测孔的标准抽水试验直接确定井损的准确值,然后用井损的准确值检验已有的各种井损经验公式,提出了消除井损的合理步骤和方法,为解决井损研究成果与工程实际长期脱节的问题提供了参考。更多还原

【Abstract】 It is necessary to identify the well loss if drawdown in the pumping well is utilized in analysis of pumping test.In this paper,the methods of well-loss identification are investigated.A standard pumping test with several observation wells is carried out and the accurate well-loss is directly obtained.Based on the checkout of empirical equations through the pumping test,reasonable routines and methods are suggested in identification of well-loss.It is available to reduce the gap between theoretical study of well-loss and observations in practice.更多还原
