钠长石化

在晚成岩期的A、B亚期阶段，方沸石的钠长石化和溶蚀对储层贡献较大。

In the A and B sub-stages of late diagenetic period , the albitization and corrosion of analcime contribute to reservoirs .

个旧矿区的热液活动及热液蚀变作用很突出，花岗岩中的热液蚀变有：碳酸盐化、绿泥石化、云英岩化、绢云母化、钠长石化。

Hydrothermal alterations in granitic rocks include carbonatization , chloritization , greisenization , sericitization and albitization .

钠长石化与铁的萃取有关，而碳酸盐化则与铁的沉淀有关。

Albitization is only related to the extraction of iron , whereas carbonatization with the precipitation of the same metal .

伊利石、绿泥石、钠长石化、孔隙充填方解石和白云石为碱性流体条件下的共生组合。

And the association of illite , chlorite , albitization , pore filling calcite and dolomite is with alkaline pore fluid .

因此，斜长石的钠长石化可见于成岩早期，而钾长石的钠长石化只发生于成岩晚期。

Therefore , the albitization of plagioclase is shown in the early stage of diagenesis and albitization of potash feldspar appears only in the late stage of diagenesis .

其次，进入中成岩期，物源来自盆地东北部的储层砂岩中大量的斜长石，通过斜长石钠长石化形成浊沸石。

Second , enter the period of diagenesis , source come from the north-eastern basin of the reservoir sandstone in a large number of plagioclase by albite plagioclase petrochemical form laumontite .

结合热动力学平衡原理分析，斜长石的钠长石化基本不受成岩温度和压力的制约，而钾长石的钠长石化需要较高的成岩温度和压力作用才能进行。

Analysis based on the equilibrium activity of thermodynamic principle shows that albitization of plagioclase is not controlled by temperature and pressure in diagenesis , and that albitization of potash feldspar depends on the increase of temperature and pressure during a diagenetic process .

亮晶方解石一般呈连晶胶结物分布，钠长石分斜长石钠长石化和自生钠长石两种产状，其中均见有丰富的油气包裹体。

Crystal Calcites are generally distributed in double Double-crystal shape . Albites have two kinds , albite from plagioclases and self-albites , where large numbers of oil and gas inclusions are seen .
