摘　　要：水位井内的水位应能真实反映河道水位变化情况,但实际上由于水位井的滞后性和测井内外水体密度差异,测井内外水位会产生误差。从水力学角度对测井水位误差进行分析,推导出测井水位误差与进水口样式尺寸和安装深度、水位最大变率、河道最大含沙量等因素之间的相互关系,并用实例对相关性公式进行应用。The water level in well logging should represent the water level variation in river channels. However,as the lag effect and water density difference,the water levels inside and outside the logging are not the same. Hydrological analysis was made to derive the correlation between water level difference and factors such as inlet types, inlet sizes, installation depth,maximum variation of water level,maximum sediment content of the river and so on. Examples were applied to correlation formulas. Water level errors and inlet design of respective measure stations can be obtained by referring to the calculation demonstration.
