摘　　要：多元热流体在稠油开发中得到了广泛的应用,但是由于其增油机理较为复杂,因此对其注入参数进行合理设计较为困难。利用数值模拟技术分析了多元热流体开发与蒸汽吞吐的作用效果差异,印证多元热流体增油机理的同时,研究了不同注入温度、注入速率以及焖井时间条件下多元热流体对开发效果的影响。结果表明,这些注入参数存在一个最佳的数值范围。进一步结合现场多元热流体应用井的实际生产数据对其开发效果的主控因素进行分析,得到注入强度、注入速度和注入温度是影响多元热流体开发效果的主要因素。研究结果为多元热流体开发工艺参数设计提供了指导。Multi-component thermal fluid had been widely used in heavy oil development,but due to their complex oil increasing mechanism,it was difficult to design their injection parameters reasonably.Numerical simulation technology was used to analyze the differences in the effects of multi-component thermal fluid development and steam huff and puff,confirming the mechanism of multi-component thermal fluid improving oil recovery.At the same time,the influence of multi-component thermal fluid on development under different injection temperature,injection rate,and soaking time conditions was studied.The result showed that there was an optimal numerical range for these injection parameters.Further combining the actual production data of on-site multi-component thermal fluid application wells,the main controlling factors of their development effectiveness were analyzed,and it was found that injection intensity,injection speed,and injection temperature are the main factors affecting the development effectiveness of multi-component thermal fluid.This provides guidance for designing process parameters for multi-component thermal fluid development.
