摘要： 为提高新疆油田稠油热采开发效果,寻求更全面、更有效的油井增产措施,针对克拉玛依油田九7+8区上侏罗统齐古组稠油油藏地质特征,开展了用复合蒸汽吞吐技术改善稠油热采开发效果的试验。采用物理模型和数模相结合的方法,进行了复合蒸汽吞吐技术机理研究,对不同原油粘度下复合蒸汽吞吐增效剂进行了筛选,对复合蒸汽吞吐岩心驱油实验结果进行了评价,并对复合蒸汽吞吐注入方式及注入参数进行了优化,为提高蒸汽驱油效率和油藏采收率提供了新的技术。

Abstract: In order to improve the development effect of Xinjiang heavy oil thermal recovery, seek a more comprehensive and more effective measures for incremental production of wells, this paper presents the experimental study by combination stimulation in view of the gelological characteristies of Qigu heavy oil reservoir in District 9(7+8), in which physical modelling and numerical modelling are carried out, including the technological mechanism, the screening and evaluation of combination stimulation expansion agent in different viscosities of crude oil, the evaluation of combination stimulation core flooding experiment and the optimization studies of combination stimulation injection process and injection parameters, as a new technology for improving the efficiency of steam flooding oil and reservoir recovery.

Key words: Karamay field, heavy oil production, combination stimulation, expansion agent, synergist, oil displacement efficiency, recovery
