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。

Abstract: The study of the relationship between the production performance and the steam chamber development by steam assisted gravity drainage (SAGD) process，the SAGD development effectiveness of Zhong?37wellblock in Fengcheng oilfield is influenced by reservoir heterogeneity，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?37SAGD pilot test area，using numerical simulation method，the technical countermeasures for improving development effectiveness are proposed such as secondary huff and puff，infilled well steam injection assisted SAGD，nitrogen gas injection assisted SAGD，and solvent injection assisted SAGD. The research provides ideas for improving the horizontal section’s producing degree，promoting the balanced development of SAGD steam chamber，and enhanced oil recovery (EOR)
