| 摘 要： | 评价断裂封闭性是油气勘探、开发和储层管理的一个重要问题.目前国内外学者正逐步把断裂疏导-封闭性的评价向半定量化一定量化发展,并结合断裂封闭演化史进行断裂多维封闭性研究.岩石纵、横波速度是地层评价和地震勘探的重要参数,衰减在地震勘探和石油地质研究中早已受到关注,但对于气源断裂的性能,一直没有很好的判断方法.笔者尝试使用波速和衰减的变化来分辨气源断裂的种类及其在成藏过程中的作用. |
| 关 键 词： | 气源断裂 超声波 波速 品质因子 |

| Abstract: | It's an important issue to evaluate the seal ability of a fault in exploration, exploitation and reservoir management in oil & gas industry. Nowadays, scholars at home and abroad are apt to semi quantitatively and quantitatively evaluate the conductibility and seal ability of a fault, and evaluate it in a fashion of multi-dimensionally with its evolution history. The transverse and longitudinal wave velocities of rock are important parameters in evaluation of stratum and seismic exploration and petroleum geology. Attention has been paid to acoustic attenuation in early time. But, it has been lacking an effective method due to characteristics of gas source faults. Therefore, we try to employ change of the sonic velocity and attenuation to differentiate the type of gas source faults and their roles in the deposition. |
| Keywords: | gas source fault supersonic wave sonic velocity quality factor |
