摘　　要：复杂断裂带在含油气盆地中具有极其重要的地质意义,它不仅体现了盆地的构造变形,同时也是盆地中油气运聚的重要区带。通过对比国内外油气充注实验,针对构造变形及烃类充注实验的关键技术问题进行了攻关,如构造模型的保护问题、密封问题、烃类着色问题等。通过改进实验装置,最大程度地保护了构造模型,防止模型的二次变形;针对装置不同构造部位密封的需求,分别研制了不同型号的密封胶;对于烃类充注放大、缩小的假象,通过添加吸色介质来真实地反映烃类充注过程。实践证实,所做的模拟实验能较好地再现地下真实的构造变形及其烃类充注过程。Complex fracture belt in petroliferous basin has extremely important geological significance, which not only embodies basin tectonic deformation, but also serves as the target for petroleum migration and accumulation. Through the comparison of domestic and foreign oil and gas injection experiments, the key technical problems of tectonic deformation and hydrocarbon injection experiments were studied, such as the protection of tectonic model, the problem of sealing up and the problem of hydrocarbon coloring. Through the improvement of device, the tectonic model was protected and the secondary deformation was prevented. Sealants of different types were designed to meet the needs of different parts of the model. For the distortion of hydrocarbon migration, color absorbing medium was added. The modeling experiment can reproduce the real underground structure deformation and hydrocarbon charging process.
