本文选择常规数字测井中采用的视电阻率、人工放射性、自然放射性等三种测井曲线,进行吕凤区童子岩组第三段中亚段13、20、22、25等四层煤层进行对比,其思路是:利用测井曲线连续性中的突变性和突变组合性规律,对它们进行对比,发现其效果显著,为利用地质模型难以精确对比的P1t3-2、P1t3-1等四层主要煤层,开辟了对比的新思路,为吕凤矿区煤炭资源开发有着重大的实际意义。 In this paper, we selected three logging curves, such as apparent resistivity, artificial radioactivity and natural radioactivity, used in the conventional digital logging to carry out the formation of 13th, 20th, 22th and 25th coal layers in the third member of Tongziyan Formation in Lvfeng District In contrast, the idea is to use the combination of mutagenicity and abruptness in the continuity of logging curves to compare them and find that the results are remarkable. It is the fourth floor of P1t3-2 and P1t3-1, which can hardly be accurately compared with the geological model The main coal seams have opened up new ideas for comparison and have great practical significance for the development of coal resources in Lvfeng Mining Area.
