摘　　要：乌尔逊断陷和贝尔断陷油气藏类型复杂。分析该区油气成藏条件和油气藏分布成因 ,将油气藏分为三大类 (背斜型 ,断块型 ,地层 岩性型 ) 10种类型。由于断陷不同部位成藏条件有差异 ,各类油气藏的油气丰度和规模有别。在此基础上提出适合复杂油气藏的勘探模式 ,包括使用滚动勘探开发的方法进行油气藏评价 ,积极采用三维地震勘探、圈闭及油气藏描述、井筒油气层识别和油气层改造等必不可少的技术。图 5参 3(张吉光摘 )Wuerxun and Beier faulted depressions are located in Hailaer basin, which are the thickest in sedimentary rocks and largest in area in that basin. They have various oil and gas reservoir, which can be classified into three major types (anticlinal, fault-block and stratigraphic-lithological reservoirs) with ten kinds according to the analyses on the conditions for the formation of the reservoirs and their distribution feature. The scale of oil/gas accumulation and their richness for different reservoirs are different due to difference in the conditions for their formation. Based on this the exploration model suitable to complex oil/gas reservoir exploration is put forward, which includes using progressive exploration and development method to evaluate oil/gas reservoirs and making actively better use of 3D seismic exploration, carrying out trap description of oil/gas reservoir, identifying oil/gas zone in wellbore, stimulating oil/gas reservoirs and adopting other necessary technologies.
