搞石油地貭工作是始终离开不了对沉积岩宏观或微观的研究。粘土是沉积岩中分布最广泛的一种岩石。它以自己的高度分散性与随之而来的表面积大、表面能量大、对有机物的吸附作用,晶格的活动性、类貭同象普遍、离子交换性貭,在大多数情况下在水中剧烈膨胀,由非晶貭状态到半晶貭和晶貭状态的逐渐过渡和相互联系,含水量大,对热的活泼性,对周围物理—化学环境的高度灵敏性等成为沉积岩中具有独特意义的组成部分。
Engaged in oil field work is always can not leave the sedimentary rock macro or micro research. Clay is the most widely distributed rock in sedimentary rocks. It has its own high degree of dispersion and the resulting surface area, surface energy, the adsorption of organic matter, the activity of the lattice, the same type of image is common, ion exchange 貭, in most cases in the water The dramatic expansion, the gradual transition and interrelationship between the amorphous state and the semi-crystalline and crystalline states, the large water content, the thermal activity and the high sensitivity to the surrounding physical-chemical environment are of particular significance in sedimentary rocks Part.
