摘要
在准噶尔盆地腹部,地震速度是影响地震资料解释过程中能否正确识别低幅度构造最敏感、最直接的地震参数。这里对准噶尔盆地腹部地震速度进行了研究;并对地震速度误差及引起该误差的主要原因进行了分析。同时,以夏盐3井区、石南4井区和夏盐南三维为例,描述了地震速度误差在准噶尔盆地腹部的表现特征,并提出了相应的解决方案。
Seismic velocity is the most sensitive and direct seismic parameter that has influence on the identification of low range structures in the Hinterland of junggar basin in seismic data interpretation. In this paper, with the study of seismic velocity, velocity error was find, and the major factors and the reason that induced the error was analyzed particularly and comprehensively. With the Xiayan 3, Shinan 4 and Xiayannan 3D seismic surveys taken as examples, the present characteristics of the seismic velocity in the hinterland of junggar bsain were described and special methods were given to solve the problems.
