摘　　要：以新疆油田某典型区域为研究对象,应用油藏数值模拟方法,对浅薄层超稠油水平井蒸汽吞吐后转换开发方式进行研究。结果表明,直井注汽水平井采油组合转蒸汽驱是较好的开发方式,合理注采参数为：注汽强度为1.68-2.02 m3/（hm^2·m·d）,采注比为1.2-1.3,井底蒸汽干度大于0.4。该研究结果对浅薄层超稠油水平井蒸汽吞吐后转换开发方式研究具有指导意义,也为稠油油藏水平井下步转换开发方式提供了思路。This paper studies the conversion of development strategy after cyclic steam stimulation in horizontal well for shallow thin ultra heavy oil reservoir by using numerical simulation and taking a typical region in Xinjiang oilfield as an example.The result shows that the combination of vertical injector and horizontal producer is a good option of steam flooding after cyclic steam stimulation.The rational parameters are the intensity of steam injectivity is 1.68~2.02 m3/(hm2·m·d),the production-injection ratio is 1.2~1.3;and the steam quality at bottom hole is over 0.4.This study is instructive to converting development strategy in horizontal wells of heavy oil reservoirs.
