摘　　要：松辽盆地外围东南部中生代残留盆地群,近年发现了良好的油气显示,实现了工业油气流井突破.但盆地之间相互关系及其成藏特征研究薄弱,制约了该区油气勘探工程的部署和资源前景预测.为此,在油气勘探工程调查的基础上,通过系统的野外地质调研和测试分析,综合研究得出:松辽盆地外围东南部中生代残留盆地皆为独立的断陷盆地,其内下白垩统的下桦皮甸子组和亨通山组发育中等—好的烃源岩,并形成了良好的自生自储、下生上储和上生下储型生储盖组合,具有一定的油气勘探前景;其隐蔽的岩性油气藏和刺穿构造油气藏是有利的油气勘探方向.In recent years,good oil-gas indications have been found in the Mesozoic residual basins in the southeastern periphery of Songliao Basin,making a breakthrough in industrial oil-gas flow wells.However,the weak research on interrelation between basins and hydrocarbon accumulation characteristics restricts the deployment of oil-gas exploration engineering and prediction of resources prospect.Therefore,based on the oil-gas exploration engineering survey,through systematic field geological survey and test analysis,it is concluded that the Mesozoic residual basins are all independent fault basins,with medium-good source rocks developed in the Lower Cretaceous Xiahuapidianzi Formation and Hengtongshan Formation,forming good source-reservoir-cap assemblages of self generation-self storage,lower generation-upper storage,and upper generation-ower storage,with a certain oil-gas exploration prospect.The subtle lithologic oil-gas reservoir and diapiric-structure reservoir are favorable exploration direction.
