摘　　要：应用王府凹陷及周边地区探井取心、录井及试油资料,结合区域沉积和构造特征的认识成果,对长春岭背斜带的气顶油环的形成过程进行了深入研究。指出双城油田具有混源特征,油主要来自三肇凹陷的青一段生油岩;王府凹陷生油能力较小,不能为双城油田的形成提供足够的油源。长春岭背斜带在嫩江组沉积末期形成过古油藏,由于以后来自深层侏罗系天然气的注入,就形成了现今的气顶油环的油气分布特征。同时提出了油藏含油边界有望扩大的具体地区。By using the data of coring, log and formation testing from Wangfu Depression and circumferential areas and in combination with the result of areal depositional and structural characteristics, the formation of gas-cap and oil-ring reservoirs in Changchunling anticlinal belt was studied. It is pointed out that Shuangcheng Oilfield has the characteristics of mixed resources, oil mainly generates from the source rocks in Qingyi Section of Sanzhao Depression. Oil generation capacity is weak in Wangfu Depression, no sufficient oil source supplies for forming Shuangcheng Oilfield. Palaeo-reservoirs were formed at the end of Nenjiang Formation in Changchunling anticlinal belt, because the later gas was injected from deep Jurassic system. Thus the characteristics of present gas-cap and oil-ring reservoir distribution are created, at the same time, the areas where oil productio limit is expected to be expanded are proposed.
