摘要通過對世界上壓扭性盆地的成盆機制、演化模式和油氣地質特點分析，總結壓扭性盆地具有6個方面的石油地質特徵：壓扭作用期間盆地的沉積速率較高，一般形成較厚的粗碎屑沉積，它們常構成很好的油氣儲集層：盆地的烴源巖往住來自於前壓扭期砂成的富含有機質的巖石，但在強烈的壓扭作用期間，在沖斷帶的前緣深坳陷（前淵）中有可能發育深水半深水相的烴源巖；壓扭（張扭）作用期間形成的雁行式褶皺（包括背斜和斷鼻等）往住是很好的油氣圈閉；壓扭作用易於成藏；壓扭作用可以促進有機質的成熟生烴作用；壓扭性盆地的周邊沖斷帶是油氣賦存的有利部位。According to these results combined with exploration practice, foot favorable exploration zones are selected, these are the integrated anticline traps below the tertiary gypsum halite, gypsum mudstone in kuqa foreland thrust belts, the second and the third row structural bells in southern junggar foreland thrust belt, the unconventional natural gas pools in die yanshan palaeohigh in north and south of western sichuan basin, the gentle fold structural belt in central sichuan basin and the deep depression in sichuan basin, and the cold take and nanbaxian structural belt in northern margin of qaidam basin

關于預制裂紋系對巖石破裂的影響，集中討論了：空障礙體構造不能阻止主裂紋的擴展，反而會使巖石的破裂強度降低近一個量級；由於構造的不同，非穿透切口樣品和穿透切口樣品的聲發射空間分佈特點有本質區別，穿透切口樣品的微破裂在切口兩端發育，而非穿透切口樣品的微破裂在切口兩端之間切口前緣處發育，這用三維破裂理論可以很好地解釋；含共線構造的巖石，裂紋外端的聲發射分佈與單裂紋構造中裂紋端部的聲發射分佈相似，裂紋內端聲發射有密集分佈，在應力達到一定水平時，內端部發生錯斷，而不是貫通。The most favourable sequences for subtle traps are cycle 3 and cycle 4, and the most favourable oil and gas - pool forming regions are jishan sandstone, fan - delta sandstone of south part of linnan sag, sliding turbidity sandstone of the slope part of shuangfen delta front and turbidity and sub - fan near fault of jiangjia dian
