| 摘 要： | 缝洞型碳酸盐岩油藏由于储集空间特殊，结构复杂，其内部流体流动形态、流动机理不够明确。根据TH油田地质资料显示的缝洞联接方式，设计了2种缝洞物理模型，采用人工造缝造洞技术制备实验模型岩心，对缝洞型碳酸盐岩注水驱油时油水遵循的流动规律、水驱油效率的影响因素、合理的缝洞数学模型以及水驱油机理进行了研究，得出了相关的研究成果，为此类油藏的开发提供了指导。 |

| Abstract: | In the fractured-cavity carbonate oil reservoirs,the reservoir space is very special and its structure is complicated.So,the flowing shape of internal liquids and its flowing mechanism are still unclear.Two fracture-cavity physical models were designed for TH oilfield based on its fracture-cavity connectivity.In these models,the artificial fracture-cavity technology is used to prepared experimental model,i.e.,cores.In addition,the oil-water flowing rule during water displacing oil,the influencing factors of... |
