木里煤田江仓矿区影响测井视电阻率曲线的因素分析

The analysis of influential factors on apparent resistivity curve in Jiangcang Mining of Muli Coaldield

通过统计九井田各煤类中固定碳、燃烧比、碱酸度、氧化物含量等相关参数,分析出井田内各煤层煤类不同,固定碳、燃烧比、碱酸度、氧化物含量均有所不同;影响煤类变化规律的因素有沉积环境、煤化作用两个方面,这两个方面的因素综合影响到各煤类有不同的组分,同一煤层不同层位也存在不同的组分,导致煤层电阻率出现幅值的差异,总结出影响测井中视电阻率曲线的主要因素是固定碳、碱酸度、氧化物含量。

According to the fixed carbon,burning ratio,acidity and alkalinity,oxide content and other related parameters of the 9 th mine field. We conclude that different coalbed have different content of fixed carbon,burning ratio,acidity,alkalinity,oxide content. The influential factors are palo- environment and coalification,which result in different sorts of coal with different groups,and different position in the same coalbed has different groups. These factors lead to the difference of resistance. Finally,we think that the influential factors are fixed carbon,acidity,alkalinity and oxide content.
