摘　　要：通过研究大庆长垣以东地区登娄库组气势场及其分布特征，将该区登娄库组划分为4个含气系统，即昌德—汪家屯—升平、肇州、尚家和朝长含气系统。通过其天然气成藏条件分析比较，得到合气条件最好的是昌德—汪家屯—升平和朝长含气系统，其次是肇州含气系统，最差为尚家含气系统。在此基础上提出了该区登娄库组天然气的二种成藏模式，即古隆起之上断背科、断块和构造—岩性圈闭天然气成藏模式和斜坡区断层岩性圈闭天然气成藏模式。By studying gas potential fields and their characteristics of Denglouku Formation in the east of Changyuan region, Daqing Oilfield, the region is divided into fOur gas bearing systems of ChangdeWangjiatun-Shengping, Zhaozhou, Shangjia and Chaochang. By comparation of their formation conditions of gas reservoirs, this paper analyses the gas bearing conditions of Changde-WangjiatunShengping and Chaochang gas bearing system are to be first, Zhaozhou gas bearing systems to be second, Shangjia gas bearing system to be third. Based on them, this paper puts forward two formation medels of the gas accumulation in the traps of fault-anticline, faultblock, structure-lithology on the ancient uplift and gas accumulation in the traps of fault-lithology on the clinoform.
