摘　　要：文章介绍了一种适合井下使用的恒流式热式流量计的原理、总体结构,并用此流量计进行了单相流低流量条件下的实验。该仪器在实验中表现出良好的分辨率,稳定性与重复性好,特别是在0.1m3/d^3 m3/d流量下,换热过程进行较慢,效果更加理想。This paper introduces a constant flow type thermal flowmeter mainly for the downhole used, describes its theory and architecture. This instrument shows good resolution, stability and repeatability when used in the single-phase flow measurements in low flow conditions. Especially in the range of flow 0.1m3/d^3m3/d, the heat transfer process is slow, and the effect of the instrument is really ideal.
