In the field construction of shale oil (gas) hydraulic fracturing, the veins present in the shale may deflect the propagation path of hydraulic fractures. The metal chalcopyrite veins are widely contained in Jimusar Shale, but the effect of the metal veins on the fracture propagation at different temperatures is still unclear. Based on the extended finite element simulation and semicircular bending test method, the effect of temperature on the interaction law of the metal veins and hydraulic fractures is studied. The results show that the fracture propagation path in the rock sample is more tortuous with the increasing temperature; Compared with the 23 °C rock sample, the fracture toughness of rock samples without the vein and with the vein at 200 °C increase by 7.79% and 22.78%, respectively. The higher the temperature, the more difficult it is for the fracture to offset at the interface between the rock and the metal veins. But the temperature does not affect the distance of fractures offset. The results of this study can provide a reference for the design of hydraulic fractures of shale with the metal veins.

在页岩油（气）水力压裂的现场施工中，页岩中存在的脉动可能会偏转水力压裂的传播路径。Jimusar页岩中广泛含有金属黄铜矿脉，但是在不同温度下金属脉对裂缝扩展的影响仍不清楚。基于扩展有限元模拟和半圆弯曲试验方法，研究了温度对金属静脉与水力压裂相互作用规律的影响。结果表明，随着温度的升高，岩石样品中的裂缝传播路径更加曲折。与23°C的岩石样品相比，无静脉和200°C的岩石样品的断裂韧性分别增加了7.79％和22.78％。温度越高 裂缝很难在岩石和金属脉之间的界面偏移。但是温度不影响裂缝偏移的距离。研究结果可为带金属脉的页岩水力压裂设计提供参考。
