摘要(Abstract)：

乌尔逊断陷是海拉尔盆地中一个具有工业油流的探区。通过对其构造发育特征分析,认为断裂控制了断陷发育,断层控制了构造带的分布,由此划分出七个构造带(西部断阶带、中部断凹带、吞-巴隆起带、东部斜坡带、苏仁诺尔断隆带、黄旗庙断凹带、西北部断鼻构造带)。指出苏仁诺尔断隆带、吞-巴隆起带是在古隆起基础上受重力作用拱张产生断层,件随形成断背斜带或滑陷背斜带。而构造带又紧邻生油区,并有较好的砂岩储集条件,是今后重点勘探的两个油气富集带。
Urxun downfatlted structural belt is p.n exploration region of commercir.l production in Hailar br.sin.The analysis of its structural history sh ows that the development of fault depression is controlled dy faulting mechan ism, and the distribution of the structural helt is controlled by faults, there fore seven structural belts can be divided as follows, western fault step, Middle fatlt subsidence, Tun-ba upwarping zone, Eastern slope, Surennuoer fault up-wsrping zone, Huangqimiao fault depression and Northwestern fault nore.It has been pointed out that both Surennuoer and Tun-ba fault upwarping zones were created by arching-extensional stress based on the ancient structute and accom panied with the formation of both faulted slumping r.nticlinal belts .The structural belts not only neighbour with oil source areas, but also are characterized by pro fitable sandstone reservoirs.The oil-gas exploration will centre on the enriched zones of hydrocarbons in the future.
