目前地震相划分主要是根据反射的波形、能量、极值、频率、连续性等进行人工划分,工作量巨大,而且主要凭经验,因人而异。自组织映照模型适合用于地震相自动划分。试验表明,其划分结果与人工划分结果能相互对应,且更为细致、准确,方法简单,处理快速。随着油气勘探的发展,该方法有较好的应用前景。 At present, the division of seismic phases is mainly based on the reflection waveform, energy, extreme value, frequency, continuity and other artificial division, the workload is huge, and mainly based on experience, varies from person to person. Self-organizing map model is suitable for the automatic division of seismic facies. Experiments show that the division result and manual division result can correspond to each other, and are more detailed and accurate, the method is simple and the processing is quick. With the development of oil and gas exploration, this method has a good application prospect.
