摘　　要：运用FAPS软件 ,对辽河盆地新开地区及双台子地区的 2条重要断层新开断层及双 42断层进行断层泥比率及滑抹因子计算 ,结合压力资料对 2条断层的封闭性进行分析 ,以指导该区的勘探部署。分析结果 :新开断层封闭性好 ,对油气成藏有重要的控制作用 ;双 42断层封闭性差 ,不控制油气成藏。分析结果与地质分析及钻探实践吻合较好 ,证明该分析方法具有较强的实用性 。By FAPS software , fault gouge ratio and smear factor are calculated for Xinkai fault and Shuang 42 fault, which are two important faults in Xinkai and Shuangtaizi area of Liaohe basin. Combining with pressure data, seal ability of the two faults have been analyzed to guide the exploration in the areas.Analysis result shows Xinkai fault is better in seal ability, and plays an significant role in controlling oil and gas reservoir, Shuang 42 fault has poor sealing ability, and can not control the forming of reservoir. This analysis result coincides well with geological analysis and drilling practice, showing this rnethod is very practical and worth of spread ing in exploration of similar areas.
