【摘要】 本文从标准土样的阳离子交换容量、盐基分量和总量的测试入手,对各种方法在与抑制钙盐和钠盐的能力进行了选择性实验,结果表明,75%乙醇-0.5mol/L氯化铵法最佳。它在中性和碱性条件下,既适用于测试各种纯粘土矿物,也适用于测试泥页岩和油气层中的粘土矿物;但对酸性土的测试,还待进一步研究。更多还原

【Abstract】 From the measurement of cation exchange capacity, salt-base component and total weight of the standard clay sample, the selective experiments on various capabilities to inhibit the calcium and sodium are made, the results indicate the method of 75% ethanol-0. 5 mol/L ammonium chloride has the best inhibitory capability. Under the neutral and alkalinity, the method is adaptable not only for the measurement of different pure clay mineral, but also is adaptable for the measurement of muddy shale and clay mineral in oil and gas bearing zone. However, in respect of the measurement of acid soil, the further study is necessary.更多还原
