PEEK材料在LNMR法测煤储层渗透率中的应用

Application of PEEK Material for Measuring Permeability of Coal Reservoir Using LNMR Method

煤储层渗透率的研究一直是煤层气等相关领域研究的热点,低场核磁共振技术(LNMR)又是研究煤储层较新的方法,由于LNMR法测煤储层渗透率对制作岩心加持器材料的要求较高,为了满足此法对仪器的要求,通过实验室现有的2种PEEK材料,分3种情况进行测试,对比分析得出,黑色材料无论和纯水一起测量还是加热后测量,信号波动都较小,是比较理想的选择。

Research on the permeability of coal reservoir is always a hot topic in the research of CBM and other related fields, and LF-Nuclear Magnetic Resonance is the new method to study coal reservoir. Due to the high requirements of core holder material when measuring the permeability of coal reservoir using the LNMR method, in order to meet the instrument requirement, designs three experiments based on the two PEEK materials in the laboratory, and conducts contrastive analysis,finally, makes the conclusion that the black material has a less signal fluctuation whenever it is measured in the pure water or after heating, which proves to be an pretty ideal material.
