【摘要】 综合运用地质、地震、钻井等资料,结合南贝尔凹陷南屯组断层特征,对海拉尔-塔木察格盆地南贝尔凹陷变换带特征进行了系统分析,认为区内发育4个二级变换带和2个三级变换带,涵盖了相向型、背向型和同向型3大类型,通过横向凸起、斜向背斜、走向斜坡和地垒变换或传递着应变和位移,对物源方向和沉积体系产生控制和影响.变换带多是油气有利聚集区.更多还原

【Abstract】 According to the geological,seismic,wells and fault characteristics of the Nanbeier depression,this paper analyzes the transfer zones of the Hailar-Tamuchage basin.Four second-order and two third-order thansfer zones are identified,covering convergent,divergent and synthetic patterns.Conversions or transfer displacement and straining are observed through lateral uplifts,oblique anticlines,which are advantageous for oil and gas accumulation.更多还原
