岩石成因学

In comparison with the petrography and petrochemistry of hydrothermal sedimentary albitite in the Devonian of the Qinling, combined with the fact that its Lower Paleozoic belongs to a passive continental-margin rift environment on the northern margin of the Yangtze plate,the authors think that the Lower Paleozoic albitite in question is probably of hydrothermal sedimentary origin.

通过与秦岭泥盆纪热水沉积钠长石岩的岩相学及岩石化学对比，结合本区下古生界属于扬子北缘被动陆缘裂谷环境，初步认为这里下古生界钠长石岩可能属于热水沉积成因。

In order to seek the favorable reservoir, thorough research on its lithofacies paleographic, sedimentary faci-es, petrologic property, pore type and petrophysical property is carried out in Chang 6 to Chang 8 reservoirs of the Triassic period according to prospects for oil and gas exploration and development at Longdong region in Eerduois Basin.

针对鄂尔多斯盆地陇东地区勘探开发前景，为寻找有利储层，对其三叠系延长组长6—长8储层的岩相古地理及沉积相特征、岩石学特征、孔隙类型及物性特征进行了深入研究，并讨论了物性与砂体成因的关系。

On the basis of analysis of different kinds of reservoir petrologic feature, porosity, rate of percolation, we can conclude that the reservoir physical characterization in most cases controlled by depositional facies.

通过对不同成因类型储层的岩石学特征、孔隙度和渗透率等方面的分析研究认为，沉积环境、沉积微相与储层砂体物性之间有直接的关系。孔隙度、渗透率在平面上的分布在很大程度上受控于沉积环境和沉积微相。

The author analyses and studies in detail through X-diffraction test of up to date special reserver samples and find that 1:1 regulation mix layers of corrensite and allevardite exists in some piecis of the eroded volcano tuff 's sandstone at the same time, and can appear continuously in a large amount In a certain limit, authors point out characteristic of corrensite and allevardite in this district and it's mining to genesis mineralogy that related to stratum water and trace element geochemistry characteristics.

作者通过最近的海拉尔盆地特殊储层样品的X衍射试验分析和详细研究，发现1：1规则混合层矿物柯绿泥石和钠板石同时存在于海拉尔盆地含火山凝灰质蚀变储层或非储层的某些井段中，而且在一定范围内的岩石孔隙中可以大量持续出现，指出了本区柯绿泥石和钠板石的组合特征，结合该区地层水和微量元素地球化学特征以及重砂特征等研究了柯绿泥石和钠板石的成因矿物学意义和其它石油地质意义。
