松辽盆地英台地区构造特征与油气藏带的分布

TECTONIC CHARACTERISTICS AND DISTRIBUTION OF RESERVOIR ZONES OF YINGTAI REGION IN SONGLIAO BASIN

根据钻井、地震和地质等实际资料，绘制了松辽盆地英台地区古构造发育“宝塔图”，构造发育剖面图，姚家组顶面构造图等有关地质图件。分析研究该区构造特征和圈闭形成条件，并根据圈闭类型组合等诸因素，确定构造有５种类型，划分出４个不同类型的油气藏带，可用于指导该区下一步油气勘探。

Abstract Based upon the data obtained from wells,seismics and geological studies,some geologi-cal maps such as the map of structural history in Yingtai area,the section map of structuralhistory,the upper structural map of Yaojia Formation etc.,were drawn,and then the tec-tonic characteristics and the forming conditions for traps were analysed.Moreover,fivetypes of structures and four types of reservoir zones are classified. All of these are valuablefor the petroleum prospecting in the region.SUBJECT TERMS:tectonic characteristics,type of traps,reservoir zones,Songliao Basin,Yingtai area,local structure
