三维相干技术评价普光气田陆相地层
|
摘要
相干体技术是通过量化处理地震数据体的相干属性,生成新的相干数据体,突出和强调地震数据的不相关性。三维相干体技术可将地震资料处理与地质解释紧密结合起来,是一种快速而直观的解释技术。三维相干技术在普光气田陆相地层地震解释中的实际应用,精确地反映了地层的不连续特征,运用效果十分显著。研究认为:应用三维地震相干体技术,能清晰地展示普光气田陆相地层断裂构造的分布和走向,解释人员能够在进行地震资料解释前即可对探区内的断裂构造异常有一个全面地了解与认识,解释断裂构造,不受人为因素影响,解释成果客观准确。这项技术对普光气田寻找勘探潜力,提高普光气田勘探效益有重要的现实意义。
Coherence technology is though the quantification of seismic data coherence properties,generation new body of coherent data,highlight and emphasize the irrelevance of seismic data.Three-dimensional seismic coherence technology data processing can be closely integrated with seismic interpretation,is a fast and intuitive interpretation techniques.Three-dimensional coherent Puguang gas field in continental strata in the practical application of seismic interpretation,accurately reflects the formation of discontinuous feature,the use of results are quite remarkable.Study suggests that:The three-dimensional seismic coherence technology,can clearly show terrestrial formation Puguang gas field distribution of faults and to explain the officers in the interpretation of stratigraphic data on the exploration in the region before the faults can be unusual to have a comprehensive knowledge and understanding to explain the results of objective and accurate.The technology of the Puguang gas field exploration potential to find and improve exploration efficiency has important practical significance.
