摘　　要：渤海Q油田稠油油藏原油粘度高,采用常规注水开发方式难以使储量得到有效动用,为此引入多元热流体吞吐技术来改善开发效果.运用数值模拟方法对多元热流体吞吐的注入参数进行优化设计,得到合理注入参数分别为：注入温度240℃,注入速度210 m3/d,周期注入量4 200 m3,焖井时间3～5 d.并对该油藏的整体开发效果进行了预测,研究结果表明,与常规水驱相比,在相同开发年限内,应用多元热流体吞吐技术可使油田的采收率得到明显提高.For Bohai Q oilfields with high viscosity of crude oil,conventional water flooding development mode is difficult to make more efficient use of reserves,therefore,the multiple thermal fluid throughput are introduced to improve the development effect.Using numerical simulation method,optimization design of the multiple thermal fluid and injection parameter has been carried out and the reasonable injection parameters are:injection temperature of 240 ℃,injection speed of 210 m3/d,cycle injection of 4 200 m3 and soak time of 3~5 d.And the reservoir prediction of the overall development effect has been made,the research results show that compared with conventional water flooding,in the same development period,the application of the multiple thermal fluid throughput technology can be of improved oilfield recovery factor.
