摘　　要：采用混合稳定流抽水试验,结合流量测井方法求取井筒基岩段各含水层的水文地质参数。根据地下水动力学原理,预测井筒施工时穿越各含水层的稳定涌水量和揭露含水层的瞬时最大涌水量。通过与实测井筒涌水量的对比结果表明,该方法预测井筒涌水量精度较高,能够为井筒施工选择防治水方案提供科学依据。Use mixed steady flow pumping test hydrogeological parameters of shaft bedrock dynamics, to forecast stable water inflow through combined with flow logging to calculate each aquifer section. According to the principle of groundwater each aquifer and instantaneous maximum water inflow when exposing the aquifer. By comparing with the measured shaft water inflow, the results show that this method can well forecast shaft water inflow ,and can provide a scientific basis for choosing water control programme when constructing shaft.
