摘　　要：为改善克拉玛依油田稠油热采开发效果,寻求一种更全面、更有效的油井增产措施,通过调研在九_(7+8)区开展复合吞吐技术改善稠油热采开发效果试验研究,利用物模和数模相结合的方法,进行复合吞吐技术机理研究、不同原油粘度下复合吞吐增效剂的筛选及评价、复合吞吐岩心驱油实验评价和复合蒸汽吞吐注入方式及注入参数优化研究。实验评价研究和预测表明,复合吞吐技术是一项稠油热采开发中后期提高采收率的有效方法,有广阔的应用前景。To improve the development effect of the thermal recov- ery of dense oil in Kelamayi oil field,study on composite steam stimulation in 9^(7+8) block is performed.Method combi- ning physical modeling with digital analog is utilized to the study on mechanism of composite steam stimulation,the se- lection and evaluation of composite synergist in different vis- cosities of crude oil,the laboratory evaluation of edge- wa- ter encroachment of composite stimulation core,the injection mode of composite steam stimulation,and the optimization of injection parameters.Laboratory evaluation and forecas- ting shows hat the composite stimulation technique is effec- tual to increase recovery ratio at the medium to later stage of thermal recovery for dense oil.
