摘　　要：研究风城油田重37井区生产动态与蒸汽辅助重力泄油(SAGD)蒸汽腔发育的关系后认为,重37井区SAGD开发效果主要受储集层非均质性、注采管柱结构、生产工艺以及注采关键操作参数等因素影响。以试验区典型井组非均质模型为基础,经数值模拟提出了二次蒸汽吞吐预热、加密井注汽辅助SAGD、注氮气辅助SAGD以及注溶剂辅助SAGD等改善SAGD开发效果技术对策,为提高水平段动用程度,促进SAGD蒸汽腔发育,提高采收率提供研究思路。The study of the relationship between the production performance and the steam chamber development by steam assisted gravitydrainage（SAGD） process,the SAGD development effectiveness of Zhong-37 wellblock in Fengcheng oilfield is influenced by reservoir het-erogeneity,injection-production pipe string structure,production process and key operation parameters of injection and production wells.Based on the typical well group heterogeneous model in Zhong-37 SAGD pilot test area,using numerical simulation method,the technicalcountermeasures for improving development effectiveness are proposed such as secondary huff and puff,infilled well steam injection assist-ed SAGD,nitrogen gas injection assisted SAGD,and solvent injection assisted SAGD. The research provides ideas for improving the hori-zontal section＇s producing degree,promoting the balanced development of SAGD steam chamber,and enhanced oil recovery（EOR）.
