摘要
在构造应力场分析的基础上,采用静封闭压力计算法和断层泥比率计算法对辽东东地区断层的垂向封闭性和侧向封闭性分别进行评价,指出断层的封闭性在时间上具有分期性,在空间上具有分段性,明确了该地区不同走向、不同性质的断层在油气成藏过程中的作用,对该地区油气勘探方向具有重要的指导意义。
Using the static sealing pressure method and the shale gouge ratio method, we studied the vertical and lateral sealing capability of faults based on the in the East LiaoDong area. It suggests that fault sealing is periodical temporally and segmental spatially. The function of the faults in different strike and with different features is assessed. It proves that the study of fault sealing capability is helpful for oil and gas exploration.
