随着科学技术水平的不断发展,二十世纪七十年代末期由于石油地震勘探领域中地震地层学的出现,地震相分析的概念逐渐被认识并被广泛应用,八十年代末期被逐渐应用到煤田地震勘探资料解释中。本文通过对辽宁省铁法外围煤炭普查地震勘探典型时间剖面的分析和研究,证明地震相分析方法在预测含煤地层及富煤带方面具有极为重要意义。
With the continuous development of science and technology, the concept of seismic facies analysis is gradually recognized and widely used due to the appearance of seismic stratigraphy in the field of petroleum seismic exploration in the late 1970s. In the late 1980s, it was gradually applied to coalfields Seismic exploration data interpretation. Through the analysis and study of the typical time profiles of coal census seismic surveys in the periphery of Tieshang, Liaoning Province, this paper proves that the seismic facies analysis method is of great significance in predicting coal-bearing strata and coal-rich zones.
