The lithological traps were the minimum oil-gas gathering and transferring stations in the course of hydrocarbon migration and accumulation. 洼陷帶巖性圈閉是含油氣盆地油氣運聚成藏過(guò)程中的小型油氣集輸站。
Though the reservoir-forming process is complex, the accumulating and preservation condition are good.Furthermore, the tectonic cleats caused by magmation promote the permeability. 雖然成藏過(guò)程較為復雜，但煤層理藏史與生烴史配置良好，有利于煤層氣富集保存，又由于發(fā)育有由巖漿誘發(fā)成因的煤層構造裂隙而使儲層滲透率提高。
