李粮店煤矿高分辨率层序地层及聚煤规律研究

High Resolution Sequence Stratigraphy of Permian and Coalaccumulation Patterns in Liliangdian Coal Mine

在研究区对II、III、IV级界面进行了识别,并对研究区地层进行了高分辨率层序地层划分,共划分出4个超长期旋回,9个长期旋回,22个中期旋回,并建立了高分辨率层序地层格架;在高分辨率层序地层学的基础上,按煤层在超长期旋回、长期旋回、中期旋回层序地层格架中的展布特征,分别进行聚煤规律研究。

In the study area, II, III and IV interface are identified, based on high resolution sequence stratigraphic, The strata of the research area are divided into 4 super long term cycle, 9 long term cycles, 22 medium-term cycles and respectively established the high-resolution sequence stratigraphic framework. According to the high resolution sequence stratigraphy, summary up the regularities of distribution of coal in sequence stratigraphic framework of super long term cycle, long term cycle and medium term cycle. and the coal accumulation law is studied.
