| 摘 要： | 针对深层油气田压裂施工的实际情况，考虑CO2泡沫压裂液变物性的影响，建立了新的拟三维模型和热力学模型，计算了陕西长庆上古油田某油井的现场压裂施工工况，计算结果表明，所建模型能较准确地预测压裂液在裂缝中的延伸与温度特性的变化，对相关油井的压裂工艺实施、参数选择及效果评估具有一定的借鉴价值。

| Abstract: | A new Pseudo-3-D model coupled with a thermal model was established. Features of fracture propagation and temperature field were investigated numerically with the consideration of the influence of variable material properties. In the simulation, spot conditions of an oil well in Shanggu oilfield were used. It is concluded that the model can be used to simulate the flow in the cracked well, and the results acquired can also be taken as reference data in fracturing working design of similar oil wells. |
