摘　　要：前人认为,松辽盆地白垩系发育6大物源及11条主要水系,但在东南隆起带又发现了一条来自榆树方向的水系并命名为榆树水系,该水系母岩为张广才岭加里东运动及印支运动期花岗岩。榆树水系从泉头组到嫩江组一直继承性发育,主要以河流和三角洲沉积为主。地质综合研究表明,榆树水系具有较大的勘探潜力,油源主要为青一段、营城组及沙河子组暗色泥岩,扶杨油层是榆树水系中、浅层勘探的主要目的层。目前该水系已经成为吉林油田增储上产的重要领域。It was believed previously that in Cretaceous of Songliao basin developed 6 large provenances and 11 major river systems. However, a new river system named Yushu river system is discovered by the authors in Dongnan （southeast） uplift, with granite as the mother rock in the Caledonian and Indosinian orogenies in Zhangguangcai mountain. This system developed from Quantou formation to Nenjiang formation is dominated by fluvial and delta deposits. The comprehensive geologic studies show that Yushu river system has great exploration potentials. Its source rocks are mainly lacustrine mudstone of the Qingshankou No.1 member, Yingcheng formation and Shahejie formation, in which Fuyang oil zone is the major target for middle-shallow petroleum exploration. At present, Yushu river system has become an important domain for incremental reserves and production in Jilin oil field.
