摘　　要：利用气势能场的分隔槽,将松辽盆地北部沙河子组—登二段含气系统划分为8个含气子系统。选取源岩、储层、盖层、圈闭和运移以及盖层与源岩、断裂活动与源岩、圈闭与源岩之间的时间匹配关系分别作为含气子系统综合评价指标,通过划分等级、赋予权值、计算综合评价权值建立了一套含气子系统的综合评价方法,并对松辽盆地北部沙河子组—登二段含气系统的8个含气子系统进行了综合评价。结果表明,古龙、安达南—昌五、肇州—肇源和双城—呼兰含气子系统为好的含气子系统,是天然气勘探的有利地区。古龙北和朝长—肇东南含气子系统为较好的含气子系统,是天然气勘探的较有利地区。By using gas potential energy field separation trough,gas bearing system in Shahezi Formation-Deng 2 Member in north Songliao Basin is divided into 8 gas bearing subsystems.Source rock,reservoir,cap rock,trap and migration,as well as time matching relationships between cap rock and source rock and between fracturing activity and source rock,between trap and source rock are respectively selected as comprehensive evaluation indexes of gas bearing subsystems.Through levels grading,weighted value assignment and comprehensive evaluation weighted value calculation,a set of gas bearing subsystem comprehensive evaluation methods are established.Comprehensive evaluation results of those 8 gas bearing subsystems show that Gulong,south Anda-Changwu,ZhaozhouZhaoyuan,Shuangcheng-Hulan,north Gulong and Chaochang-south Zhaodong gas bearing subsystems are potential areas for natural gas exploration.
