摘　　要：贝尔凹陷霍12井区主要发育两套明显断裂系,发育于铜钵庙组到南屯组的下部断裂系和大磨拐河组到伊敏组的上部断裂系,下部断裂展布主体为北东向,上部地层主体展布方向转化为南北向。霍12井区主要构造样式为铲式扇、翘倾断块等拉张构造样式,扭动构造样式及反转构造样式。Huol2 well area of Beier Depression has two significant sets of fractrues,developed in Tongbomiao Formation to Nantun Formation called lower fracture and Damoguaihe Formation to Yimin Formation called upper fracture. The main distribution of lower fracture system is North-East direction. But the distribution of upper fault system changes into North-Sorth direction. The main structural style of Huol2 well area is extensional tectonic style including listric fault and tilted fault block,shearing tectonic style, reversal tectonic 3tyle.
