平子-米桥区块煤炭测井识别研究

Study on Coal Logging Identification in Pingzi-Miqiao Block

平子-米桥区相邻区块的煤炭勘查成果显示出巨大煤炭资源潜力,在此背景下通地过钻井、测井对平子-米桥区块进行勘查。平子-米桥地区主要发育延安组煤_5、煤_6、煤_83个煤层组,煤层的测井曲线特征明显,无畸变和其它非正常显示,通过测井参数识别的方法对煤岩层定性、定厚的结果可靠,实测解释煤层20层,其中可采与评级煤层13层,全部为优质煤层,该结果为本区资源的精细勘探奠定了良好的基础。

The results of coal exploration in the adjacent block of Pingzi-Miaoqiao District show great potential for coal resources.Under this background,the Pingzi-Miaoqiao block was surveyed through well drilling and well logging.The Pingzi-Miqiao area mainly develops Yan'an coal 5,coal 6,and coal 83 coal seam groups.The logging characteristics of the coal seam are obvious,and there are no distortions and other abnormal displays.The logging parameters identification method determines the quality of coal and rock formations.The thick results are reliable,and the measured and interpreted 20 layers of coal seams,of which 13 layers can be adopted and rated coal seams,all of which are high-quality coal seams.This result has laid a good foundation for the fine exploration of the resources in the region.
