摘　　要：以新疆油田浅层稠油油藏水平井规模开发区为主要研究对象,综合运用储集层特征、生产测试、生产动态等资料,结合数值模拟研究成果,对水平井动用程度进行研究。结果表明,稠油水平井水平段动用不均衡的主要影响因素有:油层非均质性、油层钻遇率、注汽方式、水平井轨迹位置、汽窜等,利用分段注汽、均匀布汽、高温封堵、组合注汽、直井+水平井组合吞吐以及转换开发方式等可以改善水平井动用程度,进而提高稠油油藏水平井采收率。The scale development zone of horizontal wells in the shallow heavy oil reservoirs in Xinjiang Oilfield was used as an object of study,the producing degree of horizontal wells was discussed based on the data of reservoir characters,production test,production performance and the results of reservoir numerical simulation.The results demonstrate that the main influential factors of uneven production in the horizontal wells are reservoir heterogeneity,drilling ratio of oil zones,steam injection modes,horizontal well trajectory,steam channeling etc.Through subsection steam injection,even steam allocation,plugging under high temperature and combined with steam injection,composite treatment of horizontal and vertical well cyclic steam stimulation and the transformation of development mode and so on can improve the production degree of horizontal wells and enhance oil recovery factor of horizontal wells in heavy oil reservoirs.
