Experimental Study on Oil Shale Samples Fragmentation under Freezing-thawing Cycle
摘要
Abstract
In view of the important significance of the study on oil shale in-situ fragmentation for improving the heat transfer efficiency, an indoor research method of oil shale fragmentation was put forward, namely freezing-thawing cycle method. The experimental mechanism, experiment table design, sample preparation, experimental data acquisition and analysis etc. were discussed in this paper.The freezing-thawing cycle experiment was carried out on oil shale crack propagation in single hole mainly by engineering simulation.According to the design requirements, 2 groups of specimen were prepared and the experiment table was established.Simultaneously, the used oil shale samples in each experiment stage were detected by ul-trasonic detection method, which provides a feasible experiment scheme for oil shale in-situ fragmentation research and can be taken as reference to the heat transfer efficiency of oil shale research.关键词
