利用测井曲线分析双阳盆地长岭区煤系地质沉积环境

By the Use of Borehole Log to Analyze Coal M easure Strata Sedimentary Environment in Changling Area, Shuangyang Basin

利用测井曲线对吉林省双阳盆地长岭区煤系地质沉积环境进行了深入研究,利用DLW曲线并参照HGG曲线建立了解释格架(沉积模式)。得出的结论是:双阳盆地长岭区煤系地层沉积环境主要为扇三角洲沉积和湖泊沼泽沉积。并对以往工作中对本区煤系地层的对比作了修正。

The authors made a detailed study on coal measure strata sedimentary environ ment in Changling area, Shuangyang basin, Ji lin Province by the boreholelogs. By the us e of DLW (apparent resistivity log) and refe rred to HGG (density log) established an int erpretation framework (for depositional mo del). The conclusion is that the sedimentar y environment of coal measures in Changyang area, Shuangyang basin is mainly fan delta and limnetic deposits. It follows that we c orrected coal measure strata correlation i n days gone by.
