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)
