在对地震资料进行解释性处理或属性提取时,往往只是单纯的数学运算很少受到地质条件的约束.当地下岩层为水平地层时,这种方法会获得较好的效果;但地下岩层往往较为复杂具有一定的倾角,这时会使有效信号减弱从而导致资料品质下降,使开发阶段所关注的小断层的精细刻画具有较大难度.针对这个问题,本文引入地层倾角来控制解释性处理、相干和蚂蚁体的运算,并将各技术有机的结合,总结了一套切实可行的断层精细识别思路.通过对A油田断层的精细刻画,进一步深化了油田内部小断层的认识,有效指导了油田开发方案的制定和井位部署.
In the interpretation of seismic data or attribute extraction, often only a simple mathematical operation is rarely subject to geological conditions.When the underground rock formation is horizontal, this method will get better results, but the underground rock formation is often more Complex with a certain inclination, then the effective signal will be weakened, resulting in a decline in the quality of the material, so that the development of small faults of fine description is more difficult.To address this issue, this paper introduces stratigraphic dip to control the interpretive processing, coherent And ants body computing, and the organic combination of technology, summed up a set of practical idea of fault fine identification.Through the fine description of fault A field, to further deepen the understanding of small faults within the oil field, effectively guiding the development of the oil field Program development and well deployment.
