摘　　要：通过曙一区超稠油杜229块兴隆台油层的油藏基本特征和生产动态分析,发现超稠油蒸汽吞吐开发油藏平面动用程度较差,井间地带仍有大量剩余油。为了改善蒸夜空吞吐开发效果,提高油藏动用程度,在井间部署加密水平井,采用直井与水平井间的多井整体蒸汽吞吐技术,已见实效。Through analyzing the basic characteristics and producing dynamics of Xinglongtai oil layer in super heavy oil reservoirs of Du 229 block in Shu 1 area,we found that producing degree on the plane for super heavy oil reservoirs by cyclic steam stimulation development is relatively bad,and there is a large amount of residual oil among wells. For improving the development effect of cyclic steam stimulation and enhancing the producing degree,we deploy inter well infilling horizontal wells and adopt the integral cyclic steam stimulation technique in multi-wells（ vertical wells and horizontal wells）. The results show that this method is effective.
