摘要 通过对稠油热采井用防砂筛管试样进行温度载荷试验和温度循环试验,得出了试样在高温条件下的极限轴向压缩载荷,了解了高温及交变热应力对防砂筛管轴向热伸长性能的影响规律,计算出了筛管的轴向热膨胀系数。 The temperature load test and temperature cycle test were conducted on the sand screen sample used in the heavy oil thermal re- covery well. The maximum axial compressive load of sample at high temperature was gotten. The sand screen's axial thermal extension reglllarity influenced by the high temperature and the alternating thermal stress was acquired. The sand screen's axial coefficient of thermal expansion was obtained from the test data.
