用肖氏图解对比法 ,对潮水盆地西大窑煤田陆相含煤地层进行了研究 ,建立了该地区陆相含煤地层的复合标准剖面 ,获得5个等间时间界面值 ,并与传统划分方法进行比较 ,提出了定量地层(图解对比)的划分方案。依时间图解对比结果 ,纵向上划分出三个不同时间的煤组 ,并进行了远距离对比。计算出不同地段各钻孔的沉积速率 ,论述了各地段的沉积先后的差异、沉积速率与煤层的关系。
By means of the comparison of the Shaw plot, the continental coal-bearing strata of the Xidayao coalfield in the tidal basin were studied. The composite standard section of the coal-bearing strata in the continental coalfield was established. Five interfacial time interfacial values were obtained and compared with the traditional classification Methods were compared, proposed quantitative stratigraphy (graphic contrast) division scheme. According to the results of time-series comparison, three different coal groups were divided longitudinally and compared remotely. Calculate the deposition rate of each borehole in different locations, discuss the difference of sedimentation in each section, the relationship between deposition rate and coal seam.
