煤田测井资料在分析沉积环境及研究聚煤带中的应用

本文叙述了在辽宁阜新煤盆地艾友矿区,利用视电阻率、自然伽玛、伽玛—伽玛测井曲线分析沉积环境的成果,着重总结了冲积扇、扇三角洲、湖泊以及河流等环境的测井曲线特征。在此基础上,根据该区100多个钻孔的测井曲线,作出了艾友矿区沙三段地层的含砂率等值线图和煤层等厚图。通过分析这些成果图件得出了该矿区聚煤带和富煤带的分布规律。这些研究成果对于煤田的预测和勘探具有普遍意义。

THE UTILIZATION OF LOGGING DATA OF COAL BASININ THE STUDY OF DEPOSITIONAL ENVIRONMENTAND COAL-ACCUMULATED ZONE

This paper presents the results obtained from Aiyu mining area of Fuxin coal basin in utilization of such means as apparent resistivity, natural gamma, and gamma-gamma logs for analysing depositional environment with an emphatic summarization of characteristics of logs of geographic environments including alluvial fans, deltas, lakes and rivers. On such a basis and according to the logs of over 100 drilling holes in this area, the Sand-bearing contour map and isopach of coal beds have been drawn, an analysis of which leads to the discovery of the distribution regularity of coal-accumulated zones and coal-rich zones in this area. These data are of universal significance in coal predicting and exploration.
