摘　　要：沉积岩形成之初的为水平产出,但当今中的古老沉积地层却常常表现为倾斜、弯曲及不连续。这些形态各异的沉积岩归属于地壳运动改造的结果,它们与油气藏之间具有重要的联系。研究表明,构造对油气藏的储存和破坏具有重要的意义:同沉积背斜的顶部的岩性较粗、分选及渗透性好构成了储集油气的良好空间,节理是油、气运移的通道和储集油气的空间,断层的发育既可以对油气藏进行破坏又可以在适当条件下形成断层遮挡类型的油气藏。Early sedimentary rocks are flatlying, but now they often appears to be slant, curved, discrete. Crustal movements result in different forms of sedimentary rocks, which have the important connection with oil-gas pool. It is proved that geologic structure has significant effects on storing and destroy of oil-gas pool as follows： The lithology on the top of syndeposition anticline is of coarse grain, and well sorted, which forms perfect space for oil-gas pool. Oil gas moves through joints. The development of faults will not only destroy the oil-gas pool, but also form another kind of oil-gas pool under proper conditions.
