摘　　要：基于大庆萨北过渡带地层参数和流体特点，建立管式物理模型，开展了试验区复合热载体5个周期不同注入温度、注入压力、注入量、闷井时间、放喷压力条件下的复合热载体吞吐室内模拟实验，优化出萨北过渡带现场试验中复合热载体吞吐参数：注入温度为280℃、注入压力为20．9MPa、每米油层注入量为4．98×104m3、闷井时间为6．5d、放喷压力为5．4～6．5MPa，吞吐3个周期。该成果为现场试验注采参数的优化提供了有力的理论支撑，其研究方法和结论可为其他区块开展火箭动力复合热载体吞吐技术研究提供技术指导和借鉴。Considering the fluid and reservoir properties in Sabei transitional zone of Daqing oilfield,the physical pipe simulation model was established and the combined thermal carrier steam stimulation experiments were performed in five periods with different injection temperature,injection pressure,injection volume,soak time,and blowout pressure to optimize the combined thermal carrier steam stimulation parameters for field test in Sabei transitional zone. The injection temperature is 280℃,injection pressure is20. 9 MPa,injection volume is 4. 98 × 104m3 per meter,soak time is 6. 5 d,blowout pressure is 5. 4 ~ 6. 5 MPa and steam stimulation period is 3. The research results provide a strong theoretical support for the optimization of injection and production in field test.The corresponding research method can provide technical guidance and reference to the study of rocket-powered combined thermal carrier steam stimulation in other blocks.
