【摘要】 利用全区地震和钻井资料,对贝尔凹陷断裂形成及演化历史进行分析.认为贝尔凹陷发育2期断裂系统,即早期断裂系统和中晚期断裂系统,并形成4种断裂类型,即早期伸展断裂、中晚期张扭断裂、早期伸展中晚张扭长期继承性发育断裂和早期伸展中期张扭晚期反转长期发育断裂,其中后2种断裂类型控制着油气的运移和聚集及油气藏的分布范围,与油气关系最为密切.综合研究各期断裂与油气分布关系,发现贝尔凹陷油气受断裂分割在平面上呈带分布,主要发育5个断裂聚油带,即贝西北斜坡断裂聚油带、霍多莫尔断裂聚油带、苏德尔特断裂聚油带、呼和诺仁断裂聚油带和巴彦塔拉断裂聚油带,围绕断裂聚油带勘探是贝尔凹陷下一步勘探的有利方向.更多还原

【Abstract】 The paper deals mainly with the formation and evolution of the fault system in Beier Depression using drilling and seismic data,arriving at a conclusion that 2 periods of fault system have developed:early fault system and middle-late fault system;and 4 types of faults:namely early extensional faults,middle-late tensional-shear faults,inherit developed faults which are early extensional and middle-late tensional-shear,and long-term developed faults which are early extensional,middle tensional-shear and late reverse.The two late fault types have very close relationship with hydrocarbon distribution in this area,because they control the migration and accumulation of hydrocarbon,as well as the field of oil reservoir distribution.Comprehensive studyof the relationship between each period of faults and hydrocarbon distribution,we find that the hydrocarbon distribution in this area is divided by the fault system in the plane into the zone,mainly developing 5 oil-bear fault zone,which are the slope of northwest in Beier Depression oil-bear fault zone,the Huoduomoer oil-bear fault zone,the Sudeerte oil-bear fault zone,the Huhenuoren oil-bear fault zone,and the Bayantala oil-bear fault zone,so revolving around the oil-bear fault zone exploration is the beneficial direction of Beier Depression further exploration.更多还原
