摘　　要：基于面22区沙3上3砂组蒸汽吞吐开采的初期实践资料,应用数值模拟技术对其注汽参数进行优选,并分析注汽量、蒸汽干度、注汽速度、多周期注汽量变化等参数对开采效果的影响。研究表明,蒸汽吞吐方式开发应用于超薄层临界稠油油藏时,蒸汽干度应大于或等于7,焖井时间宜保持5 d,最优注汽速度为240 td。In order to apply steam huff and puff to the critical super-thin heavy oil reservoir,numerical stimulation has been used to study steam injection parameters from upper 3 in Sha 3 of Mian 22. This thesis analyzes the effect to enhance oil recovery of these parameters： steam quality,steam dryness,the changes of multi-cycle steam injection,and steam injection rate. The results show that in the process of developing critical super-thin reservoir,the steam dryness should be greater than or equal to 7,and soak time be kept about 5d and steam injection rate be best at 240 td.
